Anything Better Than OnChange - User Changes Information In A Textbox As Appose To What OnChange Does?
Jan 28, 2011Is there something that will update as soon as the user changes information in a textbox as appose to what onChange does, which is update once the focus has been taken off of the textbox? I am writing a custom cart and I am using AJAX to update the price according to how many they are ordering, I was hoping to have it update the price as soon as the user put in the volume, but it doesnt update until the user clicks somewhere else on the page.
View 3 Replies View RelatedOnChange Without Appending OnChange Directly To Element?
Feb 10, 2010Can I target the element and base an onChange outside of directly calling it in the element tag?
Due to the nature of my script, the best I can do is wrap a tag around the element.
example of what I am trying to do
Code:
<script>
document.form.field1.onchange = function();
<script>
And if this might work, can I call it in the head or must it come after the element.

View 10 Replies View RelatedJQuery :: Uncheck And Check (re-check) A Radio Input On Page Load?
Oct 4, 2011Here is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?
Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.

Code To Check Quantity For Button, But It Will Not Check For Enter Key?
Nov 9, 2011I am a php programmer and not a Javascript programmer and I am trying to help a friend out with his shopping cart. The original programmer (who wrote this years ago and is no longer around) has a button that looks up the quantities in the database for the submitted items, and then displays a prompt if you selected a quantity that is less than the minimum purchase amount.The issue is if the user enters a smaller amount than allowed and hits the enter key instead of the "Buy" button, it allows the order.how to use the current code to also check for an Enter key submission.I can handle the PHP and the db lookup for minimum quantities. Here is the page code and the Javascript code.
Code:
<a href="javascript:checkQuantity(document.form<?php echo $formCount; ?>,

Check Before Posting The Form (including A Botdetect Check)?
Jul 18, 2009I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.
[Code]...
It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.

Triggering Onchange
Jul 23, 2005I understand that the onchange event occurs when the value of a
form element changes (and after the element loses focus).
But what about the case where the value of a text box (for example)
is changed from a javascript function? Is an onclick event triggered
in such a case? I find that this is not happening in IE.
Onchange Et Firefox...
Jul 11, 2006I have a big problem with a simple event : onchange!
If I write this page:
<html>
<body>
<form id="vu">
<input id="var01" name="var01" size="5" onchange="return false;"/>
</form>
</body>
</html>
everything is ok in IE (I can't leave the input zone !) but nothing happens in Firefox!
It looks like the event is not fired or...
Do you have any clue?
Calendar And Onchange
May 23, 2007I have a button that opens a calendar and populates a text box. I use
the onclick event to open the calendar.
Now the textbox has a onChange event that calls a function. The
onChange fires perfectly if I type the date on the textbox, but if the
calendar changes the date on the field then the onChange event doesn't fire.
I even try the following, but it seems that both functions run at the
same time and the value on the field is never picked up.
Onchange Function Goes Only Once
Jun 14, 2007I was working on a site that uses Google Checkout buy now buttons, and

that, it keeps the same picture. Here;s the code:

Onchange Work With DOM
Jul 20, 2005I've written some kind of menu to display a diagram with input fields
for a budget plan. A user should be able to change values, which are initially filled by
a database value, and get all corresponding values filled by the
program.
//value given by database
showText[k].setAttribute("value", eval("liste[i][TEXT" + k + "]"));
//onchange event for the user to change the value
showText[k].setAttribute("onchange", "calculate('cost" + i + "')");
//function to recalculate corresponding values
function calculate(myId) {
if (myId == "initial") {
...
}
else {
myId = myId.slice(4);
//getParents(myId) returns corresponding values for myId
var myParents = getParents(myId);
for (var i = deep; i >= 0; i--) {
var sum = 0;
for (var j = 0; j < myParents.length; j++) {
...
for (var k = 0; k < children.length; k++) {
sum +=
parseFloat(document.getElementById(eval("'cost" + children[k] +
"'")).getAttribute("value"));
}}}}}}
My Problem is:
IE and Netscape always use the value initially entered by the database
and not the new value entered by the user.
Is there a timing or DOM problem?
Onchange Instead Of Onclick?
Jun 1, 2011I have the following code running on my site...
Code:
<script type="text/javascript"> function test_func() { alert("You clicked the map."); } </script> <form action="#"> <input type="button" onclick="test_func();" value="Test"/> </form>
It works fine, but I want the form to call test_func onchange instead of onclick. I want to add an input type='text' named call_func that when changed, will call the test_func function.

Sep 23, 2003does anyone know of a way of forcing the onChange() event of a control (it happens to be a <SELECT> if that is relevant) to fire off? (That is apart from the obvious one of changing the value with the mouse / keyboard!!!!)
I have some code which alters the currently selected element in a list and I need the list's onChange to then be fired off. The code is designed to work with many different lists, so I can't hard-code the same functionality into my code that is normally provided by the onChange.
I've tried ....element.onChange() and .....element.Change() but neither of these seem to work.
