JavaScript - Need Help With A Simple Single Field Javascript Login Form
Hello i need help with a simple single field javascript login form, i am building a small website for I and my classmates.
i want it to be able to redirect each user to a specific page when a corresponding passcode is entered, i know its unsafe but we dont plan on keeping valuable information on the site, i dont know about MSQL and dont even wish to use it, the code works at this level but am unable to add users since i dont understand javascript if someone could help me i will be very grateful thanks in advance /*here is the code i got so far*/ <tittle> Enter Passcode to proceed </title> <h1 style="font-family:Comic Sans Ms;text-align="center";font-size:20pt; color:#00FF00;> </h1> <form name="login"> Passcode: <input type="text" name="userid"/> <input type="button" onclick="check(this.form)" value="Login"/> <input type="reset" value="Cancel"/> </form> <script language="javascript"> function check(form)/*function to check userid */ { if(form.userid.value == "JohnDoe") /* checkes userid */ { window.open("johndoe.php")/*target page */ } else { alert("Invalid Passcode, please try again!")/*error message*/ } } Similar TutorialsCan someone help me I am trying to get these two values, firstname and lastname to both go into the same output box on a form. I want them to show up alongside one another like so nameform.output2.value=firstname + " " + lastname; but the values are assigned within seperate if statements as you can see below.. so I dont know how to get them to merge.. I am kinda new with javascript so any help will be very useful. Thakns very much. Code:
function checkform(nameform){
var firstname=new Array();
firstname[0]="johndefinition";
firstname[1]="jamesdefinition";
var lastname=new Array();
lastname[0]="smithdefinition";
lastname[1]="simpsondefinition";
if (document.getElementById("namebox").value.indexOf("John")!=-1)
{nameform.output2.value= firstname[0];}
if (document.getElementById("namebox").value.indexOf("James")!=-1)
{nameform.output2.value= firstname[1];}
if (document.getElementById("namebox").value.indexOf("Smith")!=-1)
{nameform.output2.value=lastname[0];}
if (document.getElementById("namebox").value.indexOf("Simpson")!=-1)
{nameform.output2.value=lastname[1];}
}
Hello all. I have created a snippet of javascript code that will do the following: 1. read the window URL 2. depending on the window URL, a word will be placed into a hidden form field. 3. Person submits form...etc., etc. Here is what I have. Let's say that I have a single landing page with a simple form on it. I would like to reference the referred URL by pulling a part of the window URL into a hidden field of the form. Let's say the three URLs a http://www.whatever.com/index.htm?id=ref1 http://www.whatever.com/index.htm?id=ref2 http://www.whatever.com/index.htm?id=ref3 I have created a javascript that takes the exact URL and check for equality. If the URL is equal, it will place the corresponding id into the hidden form field. See my code below. Code: <script type="text/javascript">
var lead_source = window.location.href
{
if (lead_source == "http://www.whatever.com/index.htm?id=ref1")
{
document.writeln("<input type=hidden name='lead_source' id='lead_source' value='ref1'>");
}
else if (lead_source == "http://www.whatever.com/index.htm?id=ref2")
{
document.writeln("<input type=hidden name='lead_source' id='lead_source' value='ref2'>");
}
else if (lead_source == "http://www.whatever.com/index.htm?id=ref3")
{
document.writeln("<input type=hidden name='lead_source' id='lead_source' value='ref3'>");
}
}
</script>
What I am looking to do is modify the code to only look at the "id" variable, not the entire URL. That way, if I add any additional items to the URL I will not have to change the code. I guess I am looking for an extra step of parsing the URL...maybe. Thanks for your help Hello all, I am working on my website at http://www.productreviewsbytyler.com, and I have a little box with one input field for e-mail address collection. I am a novice who doesn't know what is the optimal solution for just collecting the data entered into the field. I have heard of scripts that test e-mail addresses. Confused Hi everyone, im new to javascript and I have created two forms.. a value will be put in the first field and the second field should display either $20 or $35 depending on the value of the first field. Im doing something wrong here.. but I cant see what. Any help is appreciated. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Distance from Depot</title> </head> <body> <form id="distanceform"> <ul> <li> <label for="Distance from EverWarm Depot">Distance from Depot (km):</label> <input type="text" id="distance" class="large"/> </li> </ul> </form> <input name="Button1" type="button" value="calculate" onclick="deliverycost()"/> <form id="deliverycostform"> <ul> <li> <label for="Delivery Cost" >Delivery Cost:</label> <input type="text" id="deliverycost" class="large"/> </li> </ul> </form> <script> function deliverycost() { /* Here is the delivery cost: less than or equal to twenty kilometres is $20.00 greater than twenty kilometres is $35.00 */ var distance = document.forms["neworder"]["distance"].value; if(distance<20) { document.getElementById('deliverycost').innerHTML="$20"; } else { document.getElementById('deliverycost').innerHTML="$35"; } } </script> </body> </html> Hi all, I am new to JS and usually learn by studying code posted online and modify it to have it do what I need. Recently, I used a totaling plugin for an online ordering form which does the below: item1 qty(user input text) * preset price = total price item2 qty(user input text) * preset price = total price item3 qty(user input text) * preset price = total price -------------------------------------------------------- grand total -------------------------------------------------------- The JS code which passes the grandTotal variable is as below: Code: function ($this){
// sum the total of the $("[id^=total_item]") selector
var sum = $this.sum();
$("#grandTotal").text(
// round the results to 2 digits
"₹" + sum.toFixed(2)
);
}
The problem I have is the above grandTotal displays the final value when put into a table like below: Code: <td align="right" id="grandTotal"></td> But I am unable to make it work by passing it into a variable within the form fields. I would like to do something like this: Code: <input type="text" name="grandTotal" id="grandTotal" readonly="readonly" /> Can somebody please help me fix this? Any help will be greatly appreciated. Thank you. Hi guys, I have a simple calculator on my website which has a few options selectable by radio buttons. When the user adds selections - the total price of their order is automatically calculated and displayed in a <div> for them to see. The client then can deselect options or add according to their budget. The code which deals with this is as follows (just sections of it but you get the point ....) In the <HEAD> Code: <script type = "text/javascript">
var allprices = [];
var index = 0;
function chkrads(frmName,rbGroupName) {
var chosen = "";
var radios = document[frmName].elements[rbGroupName];
for (var i=0; i <radios.length; i++) {
if (radios[i].checked) {
chosen = radios[i].value;
}
}
if (chosen == 0) {printprice = 0}
if (chosen == 1) {printprice = 99}
if (chosen == 2) {printprice = 150}
if (chosen == 3) {printprice = 250}
if (chosen == 21) {printprice = 200}
if (chosen == 22) {printprice = 300}
if (chosen == 30) {printprice = 50}
if (chosen == 41) {printprice = 50}
if (chosen == 42) {printprice = 70}
if (chosen == 43) {printprice = 90}
if (rbGroupName == "size") {index = 0}
if (rbGroupName == "colour") {index = 1}
if (rbGroupName == "frame") {index = 2}
if (rbGroupName == "glass") {index = 3}
if (rbGroupName == "hook") {index = 4}
if (rbGroupName == "delivery") {index = 5}
allprices[index] = printprice;
var totalprice = 0;
for (var i =0; i <allprices.length; i++) {
if (!isNaN(allprices[i])) {
totalprice = totalprice + allprices[i];
}
}
document.getElementById("result").style.display = "block";
document.getElementById("result").innerHTML = totalprice;
}
</script>
Then in the <BODY> Code: <form name= "myform" style="font-size:11px; font-family:Arial, Helvetica, sans-serif;">
<input type = "radio" name = "size" value = "0" onclick = "chkrads('myform', 'size')"> <b>0</b>
<input type = "radio" name = "size" value = "1" onclick = "chkrads('myform', 'size')"> <b>1</b>
<input type = "radio" name = "size" value = "2" onclick = "chkrads('myform', 'size')"> <b>2</b>
<input type = "radio" name = "size" value = "3" onclick = "chkrads('myform', 'size')"> <b>3</b>
<br /><br /><br /><br />
<input type = "radio" name = "colour" value = "0" onclick = "chkrads('myform', 'colour')"><b>No</b>
<input type = "radio" name = "colour" value = "21" onclick = "chkrads('myform', 'colour')"><b>black</b>
<input type = "radio" name = "colour" value = "22" onclick = "chkrads('myform', 'colour')"><b>Multi Colour</b>
<br /><br /><br /><br />
<input type = "radio" name = "frame" value = "0" onclick = "chkrads('myform', 'logo')"><b>No</b>
<input type = "radio" name = "frame" value = "30" onclick = "chkrads('myform', 'logo')"><b>Yes</b>
<br /><br /><br /><br />
<input type = "radio" name = "glass" value = "0" onclick = "chkrads('myform', 'glass')"><b>No</b>
<input type = "radio" name = "glass" value = "51" onclick = "chkrads('myform', 'glass')"><b>Yes</b>
<br /><br /><br /><br />
<input type = "radio" name = "hook" value = "0" onclick = "chkrads('myform', 'hook')"><b>0</b>
<input type = "radio" name = "hook" value = "41" onclick = "chkrads('myform', 'hook')"><b>1</b>
<input type = "radio" name = "hook" value = "42" onclick = "chkrads('myform', 'hook')"><b>2</b>
<input type = "radio" name = "hook" value = "43" onclick = "chkrads('myform', 'hook')"><b>3</b>
<br /><br /><br /><br />
<input type = "radio" name = "delivery" value = "0" onclick = "chkrads('myform', 'delivery')"><b>No</b>
<input type = "radio" name = "delivery" value = "61" onclick = "chkrads('myform', 'delivery')"><b>Yes</b>
</form>
This all calculates the cost and then supplies the answer into this code: Code: <div id="result" style="display:none;"><strong></strong> <span id="totalprice"></span> </div> This all works exactly as I want - my question is this .... I have added an HTML contact form at the bottom of the page which goes off to a Form2Email PHP script. (All working fine) I really want to autofill one of the sections of this form "QUOTED PRICE" with the value calculated by my earlier product calculator. The form looks like so: Code: <form id="ContactForm" method="post" action="FormToEmail.php" class="input2"> <label>Name: <input name="name" type="text" id="name" value="" size="" maxlength="80" class="input"/></label> <br /><br /> <label>QUOTED PRICE: <input name="QUOTED PRICE" type="text" id="QUOTED PRICE" value="" size="" maxlength="80" class="input"/></label> <br /><br /> <label> <input type="submit" class="submit" name="submit" id="submit" value="submit"/> </label> </form> Does anyone know how to achieve this?! It would be a massive help! Hi all, Please keep in mind: this is the first code I have ever written -- much of it with help from this forum and the skeleton from other corners of the JS community. Thanks! But now for the problem... I'm developing am income tax calculator, and everything is going swell. Currently the user can type in their adjusted gross income (AGI), hit submit, and learn the amount of income tax they would pay, their tax rate, and their income after tax. I've played around with the events to get the submit button to work in FF, IE, Chrome and Safari -- and I've gotten the enter button to work before with some stock code, but here's the catch: when the user presses enter, i want the focus to leave the input box. I don't care where it goes (submit button, I suppose?) but i need it to leave the input field so the onfocus="clearText(this);" event can fire when they return to type in a new income. Any ideas? Thanks in advance. Code: <script language="javascript" type="text/javascript">

Hi Coders... I'm building a 'really simple' JavaScript program to help editors write SEO-friendly META titles and META descriptions. The idea is you have 3 text boxes, each on a separate line: BOX 1 - META TITLE [ i.e. "Cool website page" ] BOX 2 - FILE NAME [ i.e. "This is a really cool web page about cool stuff"] BOX 3 - META DESCRIPTION [ i.e. "cool-web-page" ] As the editor types in the boxes, a serp listing is displayed as it would appear on Google (and ideally how it would appear on Bing and Yahoo): Cool website page www.coolwebsite.com/cool-web-page This is a really cool web page about cool stuff Kudos to any one who could point a JavaScript newbie in the right direction I'm trying to make an xhtml form that validates itself through a javascript function. I have the form up but for some reason I can't get it to validate. I'm not even sure if I linked things correctly. Here's what I have: the xhtml file <?xml version = ″1.0″ encoding = ″utf-8″ ?> <!DOCTYPE html PUBLIC ″-//W3C//DTD XHTML 1.0 Strict//EN″ http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd> <html xmlns = "http://www.w3.org/1999/xhtml"> <head> <script src="gas24.js" type="text/javascript"></script> <h2> Registration Form </h2> <title> Javascript Form Validation Homework </title> </head> <body> <table border=""> <form name="validation_form" method="post" onsubmit="return validate()"> <tr> <td> <t>Name: <input type="text" name="YourName" size="10" maxlength="10"/> </td> </tr> </br> <tr> <td> E-mail Address: <input type="text" name="YourEmail" size="10" maxlength="24"/> </td> </tr> </br> <tr> <td> Password: <input type="password" name="YourPassword" size="10" maxlength="10"/> </td> </tr> </br> <tr> <td> Re-Type Password: <input type="password" name="passwordConfirmed" size="10" maxlength="10"/> </td> </tr> </br> <tr> <td> Your Gender: <input type="radio" name="MaleBox" Value="Male"> Male <input type="radio" name="FemaleBox" Value="Female"> Female </td> </tr> </br> <tr> <td> Comments: <input type="text" name="Comments" size="100" maxlength="500" value=""/> </td> </tr> <tr> <td> <input type="submit" value="Submit"/> </td> </tr> </form> </table> <p></p> </body> </html> The javascript file: I've tried two things. This: <SCRIPT LANGUAGE="JavaScript"> function validation() { var x=document.forms["validation_form"]["YourName"].value; if (x==null || x=="") { alert("First name must be filled out"); return false; } } And this: function validation() if ( document.validation_form.YourName.value == "" ) { alert( "Please type your name."); valid = false; } if ( document.validation_form.YourPassword.value =! "document.validation_form.Confirm.value" ) { alert ( "Please confirm your password." ); valid = false; } I would greatly appreciate it if somebody could tell me what I'm doing wrong. Hello, On my client's site: www.twdcycling.com he wanted a place where people could make suggestions for his blog. I accomplished the simple form using a textarea field and even put a little text that clears on clicks and reappears on blur. When you go there--go to the bottom left. It also actually works. The problem is that (besides the fact that so far no one has cared to make a suggestion) somehow the form is (this is what I believe) being submitted automatically. I don't believe a human is clicking submit. When I click submit w/o clicking in the field the default text that I have in the field already gets submitted in the generated email. So I now need to work on my validation in my php file that sends the email. For background I obtained my php file from html-form-guide.com here the file is in its entirety: Code: <?php
if(!isset($_POST['submit']))
{
//This page should not be accessed directly. Need to submit the form.
echo "error; you need to submit the form!";
}
$name = $_POST['name'];
$visitor_email = $_POST['email'];
$message = $_POST['message'];
//Validate first
if(empty($name)||empty($visitor_email))
{
echo "Name and email are mandatory!";
exit;
}
if(IsInjected($visitor_email))
{
echo "Bad email value!";
exit;
}
$email_from = 'tom@amazing-designs.com';//<== update the email address
$email_subject = "New Form submission";
$email_body = "You have received a new message from the user $name.\n".
"Here is the message:\n $message".
$to = "tom@amazing-designs.com";//<== update the email address
$headers = "From: $email_from \r\n";
$headers .= "Reply-To: $visitor_email \r\n";
//Send the email!
mail($to,$email_subject,$email_body,$headers);
//done. redirect to thank-you page.
header('Location: thank-you.html');
// Function to validate against any email injection attempts
function IsInjected($str)
{
$injections = array('(\n+)',
'(\r+)',
'(\t+)',
'(%0A+)',
'(%0D+)',
'(%08+)',
'(%09+)'
);
$inject = join('|', $injections);
$inject = "/$inject/i";
if(preg_match($inject,$str))
{
return true;
}
else
{
return false;
}
}
?>
It does have some validation code, and it also is set up to handle more parameters than I needed. I tried to just pare it down to the one simple thing (I just need the user to type anything they want into my text area) My reasoning is that I should be able to go get some simple validation snippet to make it so that if there is the possibility something is causing the form to just "fire off" w/o a human clicking, the validation shouldn't allow it to send, cause the text field is empty. But one would think if that is happening my default text would allow it to send, but oddly enough, no! when I get the email (last one at 5:49 am) it was a blank email! So its like some robot is doing two things: clicking in the field to empty it and THEN clicking submit! Weird, I know. But the validation code would fix this if only I knew how. (But on another note, if I try to send an empty box my default text pops back in when I click submit--proving that its happening automatically. I tried all morning yesterday to implement a snippet from several sources. Here's a couple of examples of what I added: Code:
function emptyvalidation(entered, alertbox)
{
// Emptyfield Validation by Henrik Petersen / NetKontoret
// Explained at www.echoecho.com/jsforms.htm
// Please do not remove this line and the two lines above.
with (entered)
{
if (value==null || value=="")
{if (alertbox!="") {alert(alertbox);} return false;}
else {return true;}
}
}
I didn't modify this code at all....maybe where I went wrong here. Should "value" correspond to text area name "message"? (about the only thing I didn't try) Here's another one --this one from W3 schools: Code: function validateForm()
{
var x=document.forms["myForm"]["fname"].value;
if (x==null || x=="")
{
alert("First name must be filled out");
return false;
}
}
this is how it was on the source site, all I changed was "myForm" and "fname" to "blog_suggestion" But when testing both these snippets separately what happened is that on submit I just go to my php page (which is just blank) I'm assuming code I'm adding is crashing the script somehow. And then of course no thank you page and no email sent. Finally here is my current php page in its entirety, followed by the form code on the home page... Code: <?php
if(!isset($_POST['submit']))
{
//This page should not be accessed directly. Need to submit the form.
echo "error; you need to submit the form!";
}
$message = $_POST['message'];
//Validate first
if(empty($message))
{
echo "Please enter a suggestion before clicking submit.";
exit;
}
$email_from = 'f7digitaldesign@gmail.com';//<== update the email address
$email_subject = "SOMEONE HAS SUBMITTED A SUGGESTION FOR THE BLOG!";
$email_body = "\n $message".
$to = "f7digitaldesign@gmail.com";//<== update the email address
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
//Send the email!
mail($to,$email_subject,$email_body,$headers);
//done. redirect to thank-you page.
header('Location: thank-you.html');
// Function to validate against any email injection attempts
function IsInjected($str)
{
$injections = array('(\n+)',
'(\r+)',
'(\t+)',
'(%0A+)',
'(%0D+)',
'(%08+)',

I tried to modify the validation I got w/ this to produce the "echo" message "Please enter a suggestion before clicking submit." But let's be honest, by now you know I don't know what in the heck I'm doing (it doesn't seem to matter). Form code: Code: <form name="blog_suggetion" method="post" action="send_form_blogidea.php">
<span class="bloginfotext" ><textarea name="message" rows="14" cols="12" onfocus="clearValue(this, 'Please submit ideas for our blog here—we’d love to hear from you!')" onclick="this.value='';" onblur="if (this.value == '') {this.value = 'Please submit ideas for our blog here—we’d love to hear from you!';}" ></textarea></span>
<div style="font-size:6px; color:#FFF;">sdsadfds</div>
<input type="submit" name='submit' value="submit">
</form>
Any time spent and help offered for this is greatly appreciated!! Also if you need to/want to test the field, I don't care--send me a message. I'll know someone cares! Brian I am very new to javascript and really can't figure out what I am doing wrong. I am trying to make a 1 page store that allows you to type in an item and select the color and size you want for that item. If you don't fill in a field, an alert message should tell you that. If all the fields are filled in, a "thank you for purchasing ____________" message should appear in a text area at the bottom of the page. This is my current code: Code: <html>
<head>
<script>
function processform()
{
if ( document.form1.item1.value == "")
{
alert("No Item Chosen")
}
else
{
chosen = ""
len = document.form1.c1.length
for (i = 0; i <len; i++) {
if (document.form1.c1[i].checked) {
chosen = document.form1.c1[i].value
}
}
if (chosen == "") {
alert("No Color Chosen")
}
}
else {
itemname = document.form1.item1.value;
itemcolor = document.form1.c1.value;
itemsize = document.form1.size.value;
document.form1.txtarea1.value = "Thank you for purchasing a " + itemsize + " " + itemcolor + " " + itemname;
}
}
</script>
</head>
<body>

<br/><br/>

<textarea rows="2" cols="40" name = "txtarea1"> </textarea>
</form>

</html>
When I press the purchase button, no alert message is shown, nor does anything get displayed in the textarea. What am I doing wrong? Hi everyone, I am converting a program that displays the payment options as a list of check boxes to a drop down list. I have tried using onBlur(), etc. but the program is displaying my error that says I didn't select a payment method. Here is the code, thanks for any hints or help! Code: <html>
<head>
<title>Order form</title>

{
if (document.payform.elements['item[]'][x].checked)
{
subtotal=subtotal+parseFloat(document.payform.elements['item[]'][x].value);

I have built a signup form which has several text inputs and text areas. Their labels are set as their values. When the user focuses on the field, the label text is cleared to accept text input. When focus is changed to another field. The field checks if text has been entered. If it has not, it then resets the value back to the default label value. For example: Code: <input type="text" name="company_name" size="50" class="textInput" value="Company Name" onfocus="if(this.value=='Company Name')this.value='';" onblur="if(this.value=='')this.value='Company Name';" /> What I would like to do is have some simple javascript which checks the fields on submit. If any of the required fields still have the default label value, then I would like to change the colour of the label value in the input to red and disable the form submit until the value is corrected. Most of the inputs and text areas will accept any text, though one is an email text input. I don't think any fancy validation is needed for this email input , other than checking to be sure a '@' has been entered. Since the website that this form will be contained in runs jQuery, I have looked into some plugins for form validation. However, these seem to be over-complicated for what I need. I want to keep this as simple and light as possible. Oh, and also, I am not allowed to use anything php based as this is not allowed to run on our servers for security reasons... Any advice or suggestions are much appreciated! hiiii, im new to javascripts . Can anyone help me to know that a javascript which is validating a phone number accepts only digits but if the text field is left empty it should accept the entry as an empty entry.... plz share knowledge u will be more knowledgeable Hi there, I have this listbox that I want the user to select only one choice at a time. How do I disable the multiple selection feature in javascript? <select id="lstBxEmail" name="listBoxEmail" multiple="multiple" style="width: 580px;"> <option>Java</option> <option>PHP</option> <option>Perl</option> <option>Javascript</option> <option>C#</option> <option>Powershell</option> </select> <select id="lstBxEmail" name="listBoxEmail" multiple="multiple" style="width: 580px;"> <option>Java</option> <option>PHP</option> <option>Perl</option> <option>Javascript</option> <option>C#</option> <option>Powershell</option> </select> Hi guys,I was thinking about the code to : write something inside the text box and if the word entered is equal "hero" for example the box next to it will turn green means correct, otherwise it will turn red means wrong,and if nothing entered it stays white. I really like to know how we code that in javascript using functions, without any CSS or anything else. That means we have 2 objects a text box and a rectangle for feedback color. Remark: there is no button at all, the validation will be each time you are typing. A Bonus question : if someday we decide to change the color with pictures , is it possible to do that? Thank you very much for your help, much appreciate it. Hi all, I am creating a simple 3 field calculator that calculates net, vat and gross. The user has to input 2 of the 3 fields, hit calculate and it should fill the 3rd field. I have so far succeeded with the net field (enter in gross and vat) but the other 2 throw up spurious results! I have worked out these equations (they work on a calculator) Net = G - (( G * V ) / ( V + 100 )) VAT = (( G - N ) x 100 ) / N Gross = N + ( N x ( V / 100 )) Heres the code for the javascript Code: <script type="text/javascript">
function netvatgross_calc() {
var net = (Number(document.calc.gross.value))-(((Number(document.calc.gross.value)) * (Number(document.calc.vat.value)))/((Number(document.calc.vat.value))+100));
var net = net.toFixed(2);
document.calc.net.value=net;
var vat = (((Number(document.calc.gross.value))-(Number(document.calc.net.value)))*100)/(Number(document.calc.net.value));
var vat = vat.toFixed(2);
document.calc.vat.value=vat;
var gross = (Number(document.calc.net.value))+((Number(document.calc.vat.value))/100)*(Number(document.calc.net.value));
var gross = gross.toFixed(2);
document.calc.gross.value=gross;
}
</script>
Here's the work in progress I am also wanting to add some code to throw up an error if less or more than 2 values have been entered. What am I doing wrong? Any help greatly appreciated! Cheers Dan Can we have two onFocus javascriptscript events for single HTML Tag? Thank you..
