JavaScript - Trouble With Multiple Validation Forms
Hello, I'm trying to make a simple webpage with two input text boxes that when submitted when empty, I'll get an error pop-up telling me which ones are empty, both, first name, or last name. When there's only one if, the script works. But when there's multiple else ifs, nothing happens if I press submit. Can someone help me?
Code: <html>
<head>
<script type="text/javascript">
function validateForm()
{
var x=document.forms["myForm"]["firstname"].value;
var y=document.forms["myForm"]["lastname"].value;
if (x==null || x=="" && y==null || y=="")
{
alert("Please put in your first and last name.");
return false;
}
else if (x==null || x=="")
{
alert("Please put in your first name.");
return false;
}
else if (y==null || y=="")
{
alert("Please put in your last name.");
return false:
}
}
</script>
</head>
<body>
<form name="myForm">
First name: <input type="text" name="firstname"><br>
Last name: <input type="text" name="lastname">
<input type="submit" value="Submit" onclick="validateForm()">
</form>

Similar TutorialsHey there, trying to modify a basic JS validation script Ive been using for a couple of years to work on more than one form on a page, three in fact. JavaScript (in header) Code: <script type="text/javascript">
<!--
function validate_form ()
{
valid = true;
if ( document.form.name.value == "" )
{
alert ( "Please enter your name" );
valid = false;
}
if ( document.form.phone.value == "" )
{
alert ( "Please enter your phone number" );
valid = false;
}
return valid;
}
//-->
</script>
<script type="text/javascript">
<!--
function validate_form1 ()
{
valid = true;
if ( document.form1.name1.value == "" )
{
alert ( "Please enter your name" );
valid = false;
}
if ( document.form1.email1.value == "" )
{
alert ( "Please enter your email address" );
valid = false;
}
if ( document.form1.comment1.value == "" )
{
alert ( "Please enter your message" );
valid = false;
}
return valid;
}
//-->
</script>
<script type="text/javascript">
<!--
function validate_form2 ()
{
valid = true;
if ( document.form2.name2.value == "" )
{
alert ( "Please enter your name" );
valid = false;
}
if ( document.form2.phone2.value == "" )
{
alert ( "Please enter your phone number" );
valid = false;
}
return valid;
}
//-->
</script>
and the forms... Code: <form class="cmxform" id="form" name="form" method="post" action="send.php" onsubmit="return validate_form ( );">
<input name="name2" class="custominput" id="name2" size="25" />
<input name="tel2" class="custominput" id="tel2" size="25" />
<input type="image" src="/send.png" alt="Submit Form" />
</form>
<form class="cmxform" name="quoteForm" id="quoteForm" method="post" action="send.php" onsubmit="return validate_form1 ( );">
<input name="name" class="custominput" id="name" size="25" />
<input name="email" class="email custominput" id="cemail" size="25" />
<textarea id="comment" name="comment" cols="20" rows="2" class="customtextarea" ></textarea>
<input type="image" src="send.png" alt="Submit Form" />
</form>
<form class="cmxform" id="form2" name="form2" method="post" action="send.php" onsubmit="return validate_form2 ( );">
<input name="name2" class="custominput" id="name2" size="25" />
<input name="phone2" class="custominput" id="phone2" size="25" />
<input type="image" src="send.png" alt="Submit Form" />
</form>
Ive stripped the forms down to the bones, they have default values set and onfocus commands in the full code. The problem Im having is rewriting the script above seems to work fine for the middle form but on the other two it tells me to input a valid name and then submts the form. Many thanks I have two simple forms on the site, each captures an email address they are for two separate languages. However when I try to validate, only one validates and the other one doesn't Javascript: Code: <script type="text/javascript">
function checkform ( form )
{
// ** START **
if (form.email.value == "") {
alert( "Please enter your email address." );
form.email.focus();
return false ;
}
// ** END **
return true ;
}
</script>
<script type="text/javascript">
function checkform ( form )
{
// ** START **
if (form.email2.value == "") {
alert( "Please enter your email address." );
form.email2.focus();
return false ;
}
// ** END **
return true ;
}
</script>
Form 1- It Validates Just Fine Code: <form name="quote" method="post" action="contact.php" onsubmit="return checkform(this);">
<td>
<input name="email" style=" background-color:#FFFFFF; width:200px; height:13; font-size:11px; color:#666666" type="text" /></td>
<td> <input style="border:none" type="image" name="imageField" id="image" src="submit.jpg" />
</td>
</form>
Form2 Doesn't Validate Code: <form name="quote" method="post" action="contact.php" onsubmit="return checkform(this);">
<td><input name="email2" style=" background-color:#FFFFFF; width:200px; height:13; font-size:11px; color:#666666" type="text" /></td>
<td>
<input style="border:none" type="image" name="imageField2" id="image2" src="submit2.jpg" />
</td>
</form>
Hello, and thank you for taking the time to read over my thread. I'm pretty new with Javascript coding and have been working with an example script for a new membership registration form. The original form seemed to have worked for most intents and purposes but it only contained one entry for a password field. Naturally I felt it needed a conformation field and have tried to stick one in, which is where I ran into problems. I successfully made the script throw an alert box if the two forms are the same, but it then throws another alert box of undefined function as well as throwing the same undefined function alert box even if the fields are a match. Hopefully a knowledgeable person could take a quick look at this and kindly inform me of where I'm going wrong? The code contains two of my numerous attempts to make it work (one commented out, it was easier to remember different things I have tried before to leave then in but commented out, I'm sure you all are quite familiar with that idea). Anyhow, here's the code, thank you in advance. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Hey CF, I'm currently working on a website called 'eXtreme Gaming' I've almost completed it, apart from two things. - Adding two values on my checkout page for the Grandtotal (I've tried everything, but I'm too much of a noob and have probably missed something small). - Validation of forms (I don't know where to start here, I've looked on w3schools for tuts etc but I'm having difficulty incorporating it on my site) I'm going to put the code for my checkOut page only, if you are able to help me many thanks in advance.

/quote] 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. I know that Javascript is client side, but I'd like to know the best way to populate HTML drop downs in real time based on information typed in the other HTML form fields with information found on the server as opposed to the client. For instance if a user wants to select certain files located in a directory on the server, as they type in the pathname supposedly containing the files the drop downs continually refresh themselves with the server files listed in that directory (if it exists, and apache has permissions to see what's inside) as if it was showing client files instead. What would be nice is if my browser could continually query the server for some of its private information and not have to refresh itself to obtain it, whether that means the server-side would have to continually refresh itself makes no difference to me as long as the client-side doesn't have to. But I guess this is not possible because no matter what you would have to at least refresh the client-side page once? Submitting the form to a CGI or PHP script would not work because I need this functionality to help populate the form BEFORE I send it. I would like to not have to press a button to update the form every time I change the pathname and need to update the drop downs since this would be annoying. I'm open to anything that could do this or something similar not just Javascript. I'm not sure if you could accomplish this by converting the HTML page to CGI/PHP and having it continually reload itself without refreshing the page? I'm not worried about any security risks this may pose because: 1) The server is located on company intranet which is firewalled 2) I could always password protect and encrypt all transmissions, making sure only authorized users use the app Hi all - I'm having difficulty with the processing of 3 forms on my web page. We'll call my 3 forms A, B, and C. By default my page shows form A. The other 2 forms I have hidden via display:none My issue is when I have form B or C showing. Once I hit submit, say within form B for example, I'd like this form to remain for future entries/submital of data. However, instead what happens is form A appears. How do I get form B to remain, allowing for a user to submit multiple entries of data without going back to form A? Here's my code for form 'B' <div id="branches_info" style=" <?php echo $display_branches; ?> "> form method="post" action="annual_report_main.php" onsubmit="return validateBranches(this);"> <fieldset> <p><strong>Branch Location</strong></p><br /> <label for="branch_address" class="long">Street Address:</label> <input maxlength="50" type="text" name="branch_address" id="branch_address" value="<?php echo htmlentities($_POST['branch_address']);?>" /><br /> <div class="cleaner"></div> <label for="branch_city" class="long">City:</label> <input maxlength="20" type="text" name="branch_city" id="branch_city" value="<?php echo htmlentities($_POST['branch_city']);?>" /><br /> <div class="cleaner"></div> <label for="branch_state" class="long">State:</label> <input maxlength="2" type="text" name="branch_state" id="branch_state" value="<?php echo htmlentities($_POST['branch_state']);?>" /><br /> <div class="cleaner"></div> <label for="branch_zip" class="long">Zip Code:</label> <input maxlength="10" type="text" name="branch_zip" id="branch_zip" value="<?php echo htmlentities($_POST['branch_zip']);?>" /><br /> <div class="cleaner"></div> <div class="content_onecolumn"> <input type="submit" name="Branches" value="Submit to Database" class="inputSubmit" /> </div> <div class="content_onecolumn"> <input type="button" name="Finished" value="Finished" class="inputSubmit" onclick="window.open('https://www.dca.ca.gov/webapps/bppe/thankyou.php');return false" /> </div> </fieldset> </form> </div> Hello all, I am trying to update a site that has a cookie feature enabled so that a certificate can be retrieved later on.

I have been looking around on the webs but have not found anything. I can find how to add multiple fields, but what if they reside on different forms on the same page? For example, here is my code with two forms: Code: <FORM name="form1"> <b>Size</b><input type="text" size="12" value="" name="size">* <b>Qty</b><input type="text" size="4" value="" name="qty" onkeyup="convert_to_feet(this.form);calculate_lbs(this.form)"> <b>-</b> <input type=text size="10" value="" name="a1" onkeyup="convert_to_feet(this.form);calculate_lbs(this.form)"><b>mm</b> <input type="text" size="15" value="" name="xtra">* <input type="hidden" size="4" value="304.8" name="b1"> <input type="hidden" value="0" name="ans1" size="10"> <input type="text" size="5" value="0" name="w1" onkeyup="convert_to_feet(this.form);calculate_lbs(this.form)"><b>Lbs/Foot</b> <input type="text" size="7" value="0" name="tw1" readonly="readonly"><b>Total Lbs<b> </FORM> <FORM name="form2"> <b>Size</b><input type="text" size="12" value="" name="size">* <b>Qty</b><input type="text" size="4" value="" name="qty" onkeyup="convert_to_feet(this.form);calculate_lbs(this.form)"> <b>-</b> <input type=text size="10" value="" name="a1" onkeyup="convert_to_feet(this.form);calculate_lbs(this.form)"><b>mm</b> <input type="text" size="15" value="" name="xtra">* <input type="hidden" size="4" value="304.8" name="b1"> <input type="hidden" value="0" name="ans1" size="10"> <input type="text" size="5" value="0" name="w1" onkeyup="convert_to_feet(this.form);calculate_lbs(this.form)"><b>Lbs/Foot</b> <input type="text" size="7" value="0" name="tw1"><b>Total Lbs<b> </FORM> In this example, I want to sum the two fields named "tw1" (the last field on each form) into a text box. Is this possible? fyi, I have limited experience with web programming (even less with javascript). I am trying to search a database of molecules and display several columns for each returned molecule in a table in a new page (view_all.cgi). Within this table I have a button for each molecule from the database which I would like to be able to click it and view all of it's information in a new page (view_one.cgi) However, I also have a column in my table in view_all.cgi filled with check boxes so that only some of the returned molecules can be checked and then downloaded using a script (get_checked.cgi). QUESTION: How can I handle the table data so that one button sends one row of the table to view_one.cgi, while another button sends multiple columns of the table to get_checked.cgi without using nested forms? Thanks, Tom EDIT: A better question. I have the first part of my question working (sending one row of a table to view_one.cgi). So, using javascript, how can I get the status (checked/unchecked) of all the check boxes on a page and send the information to get_checked.cgi? I'm creating a paypal webpage and am having some issues with input values updating based on which item the user has selected. The boxes I need to update are the amount, item number and item name. I have the following code but it only updates the first form. If I make a change to the second set of options it updates the first form instead of the second. Any help would be much appreciated. Code:
function details(val)
{
var info = val.split("|");
document.getElementById('num').value = info[0];
document.getElementById('price').value = info[1];
document.getElementById('package_name').value = info[2];
}
<form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<select name="dy" Onchange="details(this.value);">

Normally I would just use document.getElementById to get anything I need but here is my problem: I have a zip code control that I load using AJAX. it has city, state, country, county and zip code. This gets loaded within a business application and at one point you can have both a bill to and ship to address forms on the screen at the same time, loading my zip control with the same fields, same ids and same name. This forced me to now pass in the form name that contains the control. I need to get to divs and spans within this form. Primarily as you type in a city or zip code, I am doing a hot search with a popup div that shows you results you can quickly choose from. The only time this becomes an issue is the situation I mentioned before when the zip code control is on the screen twice. I am not certain how to access the innerHTML of a span or div by way of the form name. Is this possible and if so what is the proper syntax? Here is a very basic example at its simplest form of my problem. Code: <form name="frm_billto" id="frm_billto"> <span id="myspan">Hello</span> </form> <form name="frm_shipto" id="frm_shipto"> <span id="myspan">World</span> </form> In the above example because the control was loaded twice, I now have 2 spans with the same ID. I want the innerHTML of the each span based on the form they are in. We wanted one control that we could use throughout the system that we could update in one place and the entire application be updated. Unfortunately we did not anticipate having it load more than once on the page. Thank you for any help I have a document that contains four forms. I want to run a function only in the form the user is currently in. I keep getting the "document.my_form_name is undefined" error. I've tried all sorts of ways of doing this but can't find a solution. Here's a snippet of the HTML: Code: <form id="my_form_1" name="my_form_1" action="some action" method="POST"> // in here I call the function onchange_display_sel_droplist and // pass through the name of the form </form> <form id="my_form_2" name="my_form_2" action="some action" method="POST"> bla bla </form> Here's the part of the function in question: Code:
function onchange_display_sel_droplist(my_value, my_object, my_text_obj, my_form_name)
{
// create array with all the divs found
var arr = new Array();
arr = document.my_form_name.getElementsByTagName( "div" );
// loop through array
for(var i=0; i < arr.length; i++)
{
var tagId = document.my_form_name.getElementsByTagName( "div" ).item(i).id;
// find all the divs with ID "my_selected_div__"
if ( tagId.indexOf("add_selected_div__") > -1 )
{
// hide all
document.my_form_name.getElementById(tagId).style.display = "none";
}
}
// display selected object (droplist)
document.my_form_name.getElementById(my_object).style.display = "";
}
I posted a thread a few days ago concerning a bit of javascript code to make checking one checkbox clear another one. I got some great, prompt help. However, I just got back to working on that web page, and realized that the functions only work on the first form on my web page. I have many forms and they are actively named using php. Here's are the functions (these works for just the first form on the page): Code: <script type="text/javascript">
function undo_Changes() {
if (document.getElementById("Complete").checked==true) {
document.getElementById("Needs_Change").checked=false;
}
}
function undo_Complete() {
if (document.getElementById("Needs_Change").checked==true) {
document.getElementById("Complete").checked=false;
}
}
</script>
I call them from the checkboxes involved: Code: <input name="Complete" id="Complete" value="Yes" <?php echo($Complete=="Yes") ? "checked" : ""; ?> size="4" type="checkbox" onChange="this.style.color='#FF0000'" onClick="undo_Changes()"> <input name="Needs_Change" id="Needs_Change" value="Yes" <?php echo($Needs_Change=="Yes") ? "checked" : ""; ?> size="4" type="checkbox" onClick="undo_Complete()"> Here's how my forms are named: Code: <?php $DocName = "Schedule".$count; ?>
<form name="<?php echo $DocName; ?>" action="ScheduleCode.php" method="post" id="<?php echo $DocName; ?>">
I've tried the following and it doesn't work at all: Code: <script type="text/javascript">
function undo_Changes(myForm) {
if (myForm.getElementById("Complete").checked==true) {
myForm.getElementById("Needs_Change").checked=false;
}
}
function undo_Complete(myForm) {
if (myForm.getElementById("Needs_Change").checked==true) {
myForm.getElementById("Complete").checked=false;
}
}
</script>
<input name="Complete" id="Complete" value="Yes" <?php echo($Complete=="Yes") ? "checked" : ""; ?> size="4" type="checkbox" onChange="this.style.color='#FF0000'" onClick="undo_Changes(this.form)">
<input name="Needs_Change" id="Needs_Change" value="Yes" <?php echo($Needs_Change=="Yes") ? "checked" : ""; ?> size="4" type="checkbox" onClick="undo_Complete(this.form)">
Thanks for any help. Lisa Hi all, I have multiple forms on one page with the same element name and one of them is the <span>. Below is my sample code for a simple html file for testing purposes. I have no problem accessing the <input> element, but i had problems with the <span> element. Anyone knows why? In this scenario, i won't be able to use the document.getElementById() as both <span> have the same name. Code:
<html>
<head>
Test
<SCRIPT LANGUAGE="JavaScript">
// JavaScript statements go here
function test(tmpForm) {
window.alert(tmpFrm.elements["weight"].value);
window.alert(tmpForm.elements["error"].innerHTML);
}
</SCRIPT>
</head>
<body>
<form id="form_137" name="form_137">
<input id="weight" name="weight" value="" />
<span id="error" name="error">abc</span>
<INPUT TYPE="button" id="btnSubmit" NAME="btnSubmit" VALUE="Submit" onClick="test(this.form);">
</form>
<form id="form_137_down" name="form_137_down">
<input id="weight" name="weight" value="" />
<span id="error" name="error">zzz</span>
<INPUT TYPE="button" id="btnSubmit" NAME="btnSubmit" VALUE="Submit" onClick="test(this.form);">
</form>

I made a php page with multiple forms with javascript code in it. The javascript makes an input field for the date. The problem is that the script interfers between other scripts in the other forms and i get wrong orderdate. Code: <form action='dataadd.php' name='$id'>";
$datestime=time();
echo "<input type=hidden name=dateid value='$id'>";
echo "<input type=hidden name=datestime value='$datestime'>";?>
<script type="text/javascript">
DateInput('orderdate', true, 'yyyy-mm-dd')</script>....
hello everybody! this is my first atempt in writing javascript and i have a problem which I have no idea how to solve. I want to take the values from several dropdown forms and make some calculations whit those in order to display a number. Unfortunately the script responts in a way that i cannot identify what is happening. this is a shorten example of my script. Code:
<html>
<head>
<script type="text/javascript">
function calcul()
{
var pcno = document.plithospc.listplpc.value;
var ndno = document.plithosnd.listplnd.value;
var hotline = document.hotlform.listhotl.value;
var sumhotline = 0;
if (hotline == 2)
{
sumhotline = 8*(1+0.5*pcno) + 2*(1+0.5*ndno);
}
else if (hotline == 3)
{
sumhotline = 16*(1+0.5*pcno) + 4*(1+0.5*pcno);
}
else
{
sumhotline = 0;
}
document.write(sumhotline);
</script>
</head>
<body>

does anyone knows how to fix this? thanks in advance Hi, i'm new here and I need help. I need a script that can alert in 2 ways for multiple radio button groups of "yes" and "no." I got the first question to alert the way I need (with alert #1 for yes and alert#2 for no.) However, starting from the 2nd question it alerts #1 for both yes and no. This is the script I'm working with: Code: <script type="text/javascript">
function valbutton(form) {
myOption = -1;
for (i=form.buttonset1.length-1; i > 0; i--) {
if (form.buttonset1[i].checked) {
myOption = i; i = -1;
}
}
if (myOption == -1) {
alert("Please select Yes or No");
return false;
}
if (myOption == 1) {
alert("Yes, it works!");
return false;
}
if (myOption == 2) {
alert("No, it won't work.");
return false;
}
}
</script>
The following are the 1st two sets of radio buttons: Code: <form name="myform" action="formstest.html"> <tr> <td> <input type="reset" value="Click to Reset"> <br><input type="radio" name="buttonset1" value="1" rel="none" id="r1" /><label for="r1">Click to Start Over</label><br /></td> </tr> <tr><td class="question">Question #1</td> <td><input type="radio" name="buttonset1" value="2" rel="flat" id="r2" /> <label for="r2">Yes</label><br /> <input type="radio" name="buttonset1" value="3" rel="none" id="r3" /> <label for="r3">No</label><br /> </td> </tr> <tr rel="flat"> <td class="question"><label for="flat"><span class="accessibility">If metal:</span>Question #2</label></td> <td><input type="radio" name="buttonset2" value="4" rel="uneven" id="r4" /> <label for="r4">Yes</label><br /> <input type="radio" name="buttonset2" value="5" rel="none" id="r5" /> <label for="r5">No</label><br /> </td> </tr> Is it possible to switch out the alerts for yes and no for next 4 questions? And finally, the following is the lengthy, thorough version of my question if it clarifies what I'm trying to do. I would really appreciate someone to point me the right direction. I've tried all kinds of variation to the script and I just can't seem to make it work. Thanks in advance! (Lengthy Version) I also need questions to appear (or not show) below as select radio buttons are clicked. I have 6 groups of yes and no radio buttons. I would like the first two groups to have "alert 1" when yes is clicked (and "alert 2" for no.) I would like the rest to show "alert 2" when yes is clicked (and "alert 1" for no.) (I also have all the questions hidden below question 1. Each subsequent questions appear upon clicking yes for questions 1&2, and no for the rest. I would like to keep this intact - I put that js code I downloaded at the end of this post.) Here's what I have so far... I got most of it working except after the first question, "alert 1" appears for all the clicks submitted. I've been at it for a few weeks and I can't seem to figure it out. Thanks in advance!
