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.
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
I wanted the product picture to change based on what was picked. I was
able to have it change the picture, but if you pick a new item after
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"/>Â </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.

View 2 Replies View RelatedForms (onChange?)
Oct 11, 2005I'm making a form and I need it to do this:
From a drop-down box, the user chooses their country.
- User selects a country other than Australia, nothing happens.
- User selects Australia, another drop-down box appears with Australian states
* If they select a state other than Victoria, nothing happens
* If they select Victoria, another drop-down box appears with Region
I'd like the subsequent drop-down boxes to be either inactive and unclickable (technical terms here ) or not visible at all until the above conditions happen.
OnChange And Submission
Nov 22, 2005I've built a validation function which works great when you submit a form by clicking a button. However now I want to submit the form when the value of a input textbox changes. Actually it works fine to submit the form on the event onChange but it doesnt validate.
This is my code:
<form method="post" action="put_cart.asp" name="form1" return validera(this)">
<input name="product_id" value="<%=rs_mycart("Product_id")%>" type="hidden">
<input type="hidden" name="the_cart" value="yes">

View 3 Replies View RelatedGetting OnChange To Work With FF And IE?
Nov 2, 2011I've developed a support page where users can drop in help tickets with javascript doing client side testing of the fields for missing data etc and php for server side handling and posting to an email address. There is also a section to add supporting images, videos etc of the bug/issue using the <input type="file" /> tag.
Although I could have done server side file size checking, I didn't want my users to wait half an hour to up load a 10Mb video just to be told it was too large to send via email.
So my client side solution was to have a function fire when a file is selected:
Code:
<input type="file" id="attachment1" name="attachment[]" onchange="findSize(1)" />
The id is name 1 because I have javascript to allow the user to add multiple "Select a file" boxes, dynamically adding 1 to the id number each time. The name is an array for the server side handler of the multiple files (if any). The onchange you see fires "findSize(attachmentRef)".
Code:
function findSize(id) {
var maxFileSize = 5242880; //5mb in bytes
var idNumber = id;
var fileInput = $("#attachment"+idNumber)[0];
[Code]....
This is the findSize function that feeds back to the user instantly if the file is too big for processing - saving headaches all round. I use some jQuery to work out which file input we are looking at and to test the size of the file. If the file is too big, an alert flag is written into the form to prevent the user from hitting submit (one of my client side test conditions for checking the form confirms that this flag is 1 not 0).
Issue: The code works fine on my test browser - Chrome. But in my next step test (FF 7.0.1 and IE9) nothing happens. I can locate and add a file for upload, but the onchange doesn't fire. Or is it something in my function that is causing the bug? I'm using jQuery 1.4.4 for your info.
how to implement onchange with different browsers - something about IE and FF differing in what they mean by a change and when it happens; but I admit I'm a bit lost. Can any one spell out a solution ABC fashion?

Hot Swap Using Onchange Form
Jul 23, 2005I have seen this technique on a couple websites, but haven't been
clear on how it's done. What I am looking for is to have a form with
x-options. The technique is that when the first option is selected it
auto updates the other options to correspond. For example if I was
looking for specific cities in a state. Once a state is selected I am
only given specific cities. The end result is to combine this with
php and mysql, but I am sure if I understand the javascript aspect I
can run with it.
IE Not Detecting OnChange Properly

Jul 23, 2005In JavaScripts checks for an onChange event against the value of the

Event never fired after you changed the text first time , suppose we

If we put some other value then it became fired...
It wouldn't fire if we put the same value...
I don't want to use onBlur etc... Isthere any solution with onChange

entered is incorrect and reset it back to previous correct value. How could i do it using onchange event of the text box.
