JQuery :: OnChange Event - Web Application - Each Blur Event Makes A Call Webserver To Store Value Of Textfield

Jan 21, 2010

I'm currently facing a weird issue with the onchange event. I have a web application where each blur event makes a call the webserver to store the value of the textfield. I only want to trigger that ajax call when something has changed, so i track the onchange event on each textfield to set a flag if something has changed.

The onchange event always fires to first time when i click outside of a textfield even if i didn't change anything in the field.

I narrowed it down to the following: A prefilled textfield always fires the onchange-event the first time you leave the textfield. An initially empty textfield does not fire the onchange event.

Sample code (IE 8 on Windows 7 computer):

script:

HTML:

Handle Objects And The 'this' Keyword When Using Event Listeners?

Feb 24, 2009

So I know all about the caviats of the 'this' keyword when calling object functions from event listeners:

Code:
var foo = {bar: true, zoo: function() { return this.bar; }};
foo.zoo();
> true
a = foo.zoo;
a();
>

And I know that I can get around this by using an anonymous function so that 'this' is preserved in it's original context:

[Code]...

But then someone pointed out this article on memory leaks when using anonymous functions to call object methods because the anonymous function gets access to ALL variables in the enclosing environment and my not be properly disposed of by the garbage collector [URL] So that lead me to think about using a "3rd-person" approach to referencing object properties from within object methods.

Handle A Callback Event Before It Performs The Default Href Function?

Mar 1, 2010

how to handle a callback of an event, before it performs the default href function.

<code>
<a href = '<?php $url ?>' onclick = myFunction(); return true;>Click Here</a>
</code>

I want the onclick event to finish completing and then perform the default href function, which is denoted by the "return true". The javascript "myFunction()" opens a window in a pop-up and it has a submit button in it. I would like to wait till this page loads in the pop-up window and only after the user clicks on the close button, the default href function needs to be carried out. I cannot figure out on how to get the callback from this event.

this.value = this.value.replace(/[^0-9.]/g,'');

Ok, so the above code will do the regex when the contents of the textbox changes, but it does not seem to call the checkPrice function I've placed after it does the regex.

I have the above on Change code in a .keyup event and it works as expected.

OnChange Event Is Not Working

Jul 23, 2005

In JavaScripts checks for an onChange event against the value of the
textbox at the time of the last onChange event. Since an onChange
Event never fired after you changed the text first time , suppose we
put the same value in the text box then no event is fired.

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
Event...?

Eg:
