JQuery :: Click-Event Is Not Registered

Jul 4, 2011

In my current work i try to put several links onto an image. I do this with AJAX:

$('.panorama').load("getContents.php", {id : "5"});

This inserts several links into my container "panorama". They look like that: <a class='poi' style='margin-top:141px; margin-left:365px;' href='#6'></a>

The problem is, that a click on those links is not registrated by my java-script
code. I tried it this way:

$('a.poi').click(function(){
var hash = $(this).attr("href").substr(1);
console.log(hash);
if(hash)

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:

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...?

Cancel OnChange Event

Jul 23, 2005

I Have a text box in a jsp that is pre populated. The text box should accept only numbers and it should be greater than a minimum value (this value depends on the user settings). If the user enters a value less than the minimum value, i should pop up an alert saying that the value
entered is incorrect and reset it back to previous correct value. How could i do it using onchange event of the text box.

OnChange Event And Focus()

Jul 23, 2005

Am I right in assuming that you can NOT set focus() back to a field in
its onChange event? Is there another way - I have validation that I
would like to set the focus back to the invalid field onChange?

Eg:
<input type=text" name="tstfld" onChange="window.alert('Changed!');
this.focus()">

OnChange Event Not Working In IE Properly / Fix It?

Aug 19, 2009

I have the following code which works fine in FF but not in IE. code...

In FF, when you change the Fund dropdown to be Romanian Floods, the location dropdown disappears and the location_box text box appears which displays the second part of the value (Romania). If you select another value from the Fund dropdown again, this box disappears and the location dropdown box would appear again. This is exactly what I need it to do.

In IE, whenever you select anything in the Fund dropdown (doesn't matter whether it is Romanian Floods or anything else), the value in the Fund dropdown disappears and thus when I press submit it doesn't work!

Using An Eventlistener To Cancel An Onchange Event

Nov 15, 2006

I've got to write some javascript to listen for a select 'change' event. Unfortunately, the select box has an onchange event as well. For example:

<select name="test" onchange="document.form.submit();">

Here's my event listener:

function handle_submit() {
return false;}

function addListeners() {
if (document.addEventListener) { document.form.test.addEventListener('change',handle_submit,false);
}}

window.onload = addListeners;

Now, the event listener does capture the event, but I want to cancel the onchange event within the select box. Is that possible?
