.... any help? ..Much thanks Everyone! Similar TutorialsI have a simple html form with 2 text fields and submit button 1 user name 2 pwd/token and 1 checkbox 'First time user' if 'first time user' is selected then the 'Submit' button to be enabled only if the customer puts exactly 6 digits on pwd/token. if it's unchecked then the submit button to be enabled only if the customer enters 10 digits(pin_token code) please send me code will be very thankful for your help Hey guys, First shot at JS so please be gentle! I'm trying to get this script to clear the default value of my input elements on focus. It works well the first time, however, if a user inputs some fresh text, selects something else, then selects the same input element again, it will clear the text they entered. Make sense? Here's the script (thanks in advance!!): Code: <script language="JavaScript">
function clickFocus(input){
input.className = 'focus';
if (input.value = input.defaultValue){
input.value = '';
}
}
function unFocus(input){
input.className = 'entered';
if (input.value == ''){
input.value = input.defaultValue;
input.className = 'normal'
}
}
</script>
<form action="confirmation.php" method="post" enctype="multipart/form-data" name="form" id="form" onsubmit="return checkForm(this)">
<input type="text" name="name" value="Name" onfocus="clickFocus(this)" onblur="unFocus(this)" />
<input type="text" name="email" value="Email" onfocus="clickFocus(this)" onblur="unFocus(this)" />
<input type="text" name="subject" value="Subject" onfocus="clickFocus(this)" onblur="unFocus(this)" />
<textarea type="text" name="message" onfocus="clickFocus(this)" onblur="unFocus(this)" rows="5">Message</textarea>

Hello. I've been teaching myself HTML and CSS for a while, and now I've moved into the world of Javascript (but I'm still very much a beginner). For practice, I've been building a sample sign up form for a mock website, and I'm having problems with the birthdate section. The idea I had was to have MM, DD, and YYYY be the default values of my 3 textboxes (as an example for users), then set the value to nothing when the box gained focus. That all works fine, but I ran into problems when I tried to write an if statement to set the value back to MM, DD, or YYYY if the value was still nothing when the user clicked away. As it is now it just replaces the text inputted into the textbox (which of course is not good). Any ideas for what the problem might be? Code: <form name="signup" action="javascript:void(0);" method="post">
<table>
<tr>
<td>Date Of Birth:</td>
<td>
<input name="DOBmonth" type="text" value="MM" size="2" style="color: #555555;" onFocus="clearDOBmonth()" onBlur="restoreDOBmonth()" />
<input name="DOBday" type="text" value="DD" size="2" style="color: #555555;" onFocus="clearDOBday()" />
<input name="DOByear" type="text" value="YYYY" size="4" style="color: #555555;" onFocus="clearDOByear()" /></td>
</tr>
<tr>
<td></td>
<td><button name="Submit" type="submit" style="font-size: 1em;">Sign Up</button></td>
</tr>
</table>
</form>
<script type="text/javascript" language="javascript">
<!--
document.signup.DOBmonth.value="MM";
document.signup.DOBday.value="DD";
document.signup.DOByear.value="YYYY";
function clearDOBmonth() { document.signup.DOBmonth.value="";}
function clearDOBday() { document.signup.DOBday.value="";}
function clearDOByear() { document.signup.DOByear.value="";}
function restoreDOBmonth()
{
if ('document.signup.DOBmonth.value = ""')
{
document.signup.DOBmonth.value = "MM";
// alert(document.signup.DOBmonth.value);
}
}
//-->
</script>
Another side question, if I set a variable equal to the value of a textbox, then change the value of the variable, does that also change the value of the textbox? or is the variable no longer associated with the textbox. Example: Code: var a = document.form.textbox.value; a = blue; does document.form.textbox.value = blue? or is var a now completely independent of the textbox value? Thanks! Hi, I have a form that when you click submit gives a warning box asking if to continue code below Now when I type in the text field and press enter it doesn't submit nor does it pop up the warning box, how would I do this Code for submit button Code: <script LANGUAGE="JavaScript">
<!--
function submitMyForm()
{
var agree=confirm("ARE YOU SURE ?");
if (agree)
return true ;
else
return false ;
}
// -->
</script>
Code: <form action="admin-delete.php" method="post" name="cp_delete" id="cp_delete"> <input type="text" name="cp_delete_bg" id="cp_delete_bg"> <input type="submit" name="submit" value="submit" onclick="return submitMyForm()"/> </form> I'm sort of new at JS and trying to have an option to clear the fields by pressing the clear fields button, but nothing happens. This should be correct but for some odd reason it's not.. In addition, I have to edit my fuction doSubmit so once submitted an alert box with all the information is in it.. Does that make sense So the alert should be: John Does 462 Smith St Johnston, NC 44524 Email@com 214-854-6555 Etc Code: <script>

super thanks!!!!!! -pumpkin I need to learn how to clear form fields when a user clicks on them. Here is the site in question: http://www.yourvancouvermortgagebroker.ca/apply They used to work, but then I changed the field value and now it doesn't work on some of the fields (whichever ones I changed). Here is a link to the .js file: http://www.yourvancouvermortgagebroker.ca/js/apply.js ok, i'm sure you all will laugh at this, but it seems really bizzario to me. i have two small routines worked out. routine G gets a value out of the db and brings it back to the browser script. routine P puts a value into the db from the browser script. they both run fine. but......... you have to turn the browser totally off and restart it after retrieving a value out of the db (?) why? is this some kind of "clear memory" i need to be doing. its like the last value i retrieved thru the server is stuck in memory and keeps coming up, and it won't flush out until i turn the browser off and restart it. is this a Javascript problem or a PHP problem? i dont' have a clue, maybe i need to somehow flush the memory in the PHP file after i echo() back the result.? is that normal? thanks, Paul I need to clear the default value from a textarea when a user clicks on the textarea and then replace it if the user clicks away from the textarea without modifying it. I have managed to accomplish this with the textfields in my forms but I am struggling to get the textarea element to mimic this behavior. Here is the script I am using: Code: addEvent(window, 'load', init, false);
function init() {
var formInputs = document.getElementsByTagName('input');
for (var i = 0; i < formInputs.length; i++) {
var theInput = formInputs[i];
if (theInput.type == 'text' && theInput.className.match(/\binput\b/)) {
/* Add event handlers */
addEvent(theInput, 'focus', inputText, false);
addEvent(theInput, 'blur', replaceDefaultText, false);
/* Save the current value */
if (theInput.value != '') {
theInput.defaultText = theInput.value;
}
}
}
}
function inputText(e) {
var target = window.event ? window.event.srcElement : e ? e.target : null;
if (!target) return;
if (target.value == target.defaultText) {
target.value = '';
}
}
function replaceDefaultText(e) {
var target = window.event ? window.event.srcElement : e ? e.target : null;
if (!target) return;
if (target.value == '' && target.defaultText) {
target.value = target.defaultText;
}
}

I have it working on the text field but no the textarea. Help! I have a page with a form on it and a button that opens a new window for them to verify the data. What happens is that when the window opens, the form gets cleared out. This is with FireFox (IE has issues too!) Now this code has actually work fine for several years, now all of a sudden it's an issue. Possibly browser update issues? Here's a VERY stripped down version that shows the problem: Code: <HTML>

Ideas??? This is some of the script that I have and it works well. The story is that I have a drop down list and depending on the selection a different set of text is displayed below the list. Code: if (Val == "general")
{
document.getElementById('Link0').innerHTML="<font size=2><a Href='http://www.web1.com/'>web 1</a>"
document.getElementById('Link1').innerHTML="<font size=2><a Href='http://www.web2.com/'>web 2</a>"
However when the selection runs this part of the code:- Code: if (Val == "duties")
{
document.getElementById('Link0').innerHTML=""
document.getElementById('Link1').innerHTML="<font size=2><a Href='http://www.web2.com/'>web3</a>"
The "web 3" text is placed under where the 'Link0' text would have been if there had been some. So basically what I need to do is set the 'Link0' text to nothing and have the 'Link1' text sit in its place. I know I could just put the 'Link1' text in the 'Link0' element but I have other controls on the screen that mean I need to run it as it is. I hope that is clear, cheers Daniel. I have created some online software which uses form data to submit to another page. The problem is that I have other submit buttons in the same form which submit to different pages (depending on which button is pressed). The first submit button works fine but all the others only work once. Code: <input class="cssbutton" type='submit' value='Button1' onclick="wbform.action='page1.php'; target='mainFrame'; return true;"> <input class="cssbutton" type='submit' value='Button2' onclick="wbform.action='page2.php'; target='_blank'; return true;"> <input class="cssbutton" type='submit' value='Button3' onclick="wbform.action='page3.php'; target='topFrame'; return true;"> <input class="cssbutton" type='submit' value='Button4' onclick="wbform.action='page4.php'; target='topFrame'; return true;"> <input class="cssbutton" type='submit' value='Button5' onclick="wbform.action='page5.php'; target='_blank'; return true;"> <input class="cssbutton" type='submit' value='Button6' onclick="wbform.action='page6.php'; target='_blank'; return true;"> Any ideas my friends? Hi all Is using the real form submit button a problem in any way? Can it actaully send a form when a person uses 'enter' in a text field. When I use this submit, it triggers my validation which is great. Code: <input type="submit" value="OnSubmit validate" /> However this way doesn't seem to trigger my validation although It may solve the above form send problem (if that realy exists). How do I get it to act the same as real submit so it will trigger validation like onsubmit above? Code: <input type="button" value="Send Feedback" onclick="this.form.submit()" /> LT does any of that make sense? all ideas helpful and appreciated I've got the following 2 fields in my form: <input type="file" name="filename" id="filename" value="filename"> <input type="submit" name="submit" value="Upload Image" /> Now I want to hide both of them as soon as the submit button is pressed. Problem is that I'm a javascript noob and I can't find it with google :S Can someone help me? Hi there, this is my first post. I'm very new to javascript and have been programming a "beer counter" that simply counts +1 into a text object after every click. After I got this to work I copied the code in order to make a clear button / function. I've been having problems, even though the code seems to be identical. This is likely an obvious question, pardon my inexperience. <html> <head> <title>Beer Counter</title></head> <body><script language="Javascript"> var beers = 0 var output ="" function beer() { beers = beers + 1 output = document.getElementById('output') output.value = beers } function clear() { beers = 0 output = document.getElementById('output') output.value = beers } </script> <input type='button' value='Crush' onclick='beer()'; /> Beer count:</input> <input type='text' id='output' name='output'; /><br/> <input type='button' value='Clear' onclick='clear()'; /> </body> </html> I'm working with datepickers to select a date range for my travel site (so they are a departure date and a return date). There are two datepickers and I can't get the min date on the first calendar set to today, and I also can't figure out how to get the date fields to clear if the user clicks the browsers refresh button - please help! Here's the javascript code I'm currently trying to run: $(function() { var dates = $("#datepicker1, #datepicker2").datepicker({ defaultDate: '', minDate: '+0m +0w +0d', // this isn't working to set the earliest selectable date to today maxDate: '+0m +0w +365d', // but oddly enough this one works to make sure users can't select a date farther than a year out numberOfMonths: 2, beforeShow: function() { var other = this.id == "from" ? "#datepicker2" : "#datepicker1"; var option = this.id == "from" ? "maxDate" : "minDate"; var selectedDate = $(other).datepicker('getDate'); $(this).datepicker("option", option, selectedDate); } }).change(function(){ var other = this.id == "from" ? "#datepicker2" : "#datepicker1"; if($('#datepicker1').datepicker('getDate') > $('#datepicker2').datepicker('getDate')) $(other).datepicker('setDate', $(this).datepicker('getDate')); }); }); // this is the function I wrote to try to clear the fields when browser refresh is clicked but it doesn't do anything function clearInp() { document.getElementById('datepicker1').value = ""; document.getElementById('datepicker2').value = ""; } Here's the corresponding HTML code: <form method="POST" name="myForm2" class="calendars"> <input id="datepicker1" type="text" name="departure_date" class="dates" size="15" maxlength="25" /> to <input id="datepicker2" type="text" name="return_date" class="dates" size="15" maxlength="25" /> </form> Thanks in advance! Hi- I have a table with numerous textareas that I am able to clear once - the first time the textarea is clicked the default value is cleared and everything is OK. However, at a certain point the user might press a 'Clear' button linked to a function I wrote to reset the values back to the defaults. At this point clicking into the textarea does not clear it. Below is a typical textarea: Code: <textarea rows= "2" cols="15" class="Klabel" id="ta5" onfocus="this.value=''; this.onfocus=null; setbg_color('ta5','#EFA746')" onchange="setbg_color('ta5', '#EBF5FF')">
Type a label
</textarea>
Below are the relevant functions. The Clear function mentioned above just runs 'setbg_color' and 'set_value' for each textarea and sets them to the defaults. Code: function setbg_color(id, color){
document.getElementById(id).style.background=color;
}
function set_value(id, celltype){
document.getElementById(id).value=celltype;
}
Is there anyway to essentially reverse the effects of the this.onfocus=null; statement? I tried something like this.onfocus=true; but that didn't work. An update - I haven't answered the reversing null question but an acceptable solution is to reload the page from within javascript as per http://www.mediacollege.com/internet...ge/reload.html Thanks -Jim ps - As part of my research I came across this http://mvied.com/blog/unobtrusive-input-clear-focus/ which does a smoother job of clearing the textareas but does not solve my question. Hello all. Complete newbie to this and to be quite honest, completely out of my depth. Ok, I have the following set up on my page - the page essentially uses three different search methods to bring back data in a gridview. 1. A cascading drop down list (ddlBuyer, ddlSub, ddlProd) and an associated radio button radBuyer. 2. An autocomplete textbox (tbxProdAC) that sources product information and an associated radio button (radProd) 3. A text box whereby users specify the number of products they wish to see and (txtHowMany) a subsequent sub category radio button list that breaks the products down further (radTopx) What I would like to do is essentially make the page so that a user can only user one of the above methods and the radio is focused according to what the user first specifies. For example, if they wish to use the ddl method, they should click ddlBuyer, ddlSub and ddlProd and the focus is placed upon the radBuyer. Along side of this, any information that may have been entered into tbxProdAC or txtHowMany is cleared. Alternatviely, should a user use the drop down method then wish to use the third method specified above, once a user clicks in txtHowMany, the ddl should revert back to their original values. I would like to achieve this in the c# code behind and I currently have the following code on my page load event/ I have got to the point where I am going round in circles (mainly because I don't know what I am doing!) so I would appreciate a few pointers. Code: ddlProd.Attributes.Add("onchange", "return SetRadioFocus('" + radBuyer.ClientID + "');");
radTopx.Attributes.Add("onclick", "return SetRadioFocus('" + radTopx.SelectedItem + "');");
tbxProdAC.Attributes.Add("onclick", "return SetRadioFocus('" + radProd.ClientID + "');");
ClientScript.RegisterClientScriptBlock(this.GetType(), "MyScript", @"
function SetRadioFocus(target)
{
document.getElementById(target).checked = true;
}"
, true);
If someone can help me, I would be extremely grateful and it would save me from smashing my head further into my desk. Please excuse my ignorance, brand spanking new to this and feeling more than a little thick. |
