Accessing The Class From Event Trigger
Feb 13, 2009
Bit of a problem I've not been able to solve after a couple hours. I'm new to Javascript classes and objects and really a Perl programmer so this has been giving me a headache. I've attached the code below but in a nutshell I have an object that writes code to a div upon instantiation and attaches events to several controls. When the event fires it runs a function attached to the class via prototype.
Problem is, the "this" obj from this event now refers to the control (e.g button) so there is no way to get back to the class. If you look at " alert(this);" line this should output the Class object, instead it refers to the button

I'm using jquery to make it easy for AJAX calls.
So I create a class: function cMap(mapID){//vars and stuff}
I go and prototype a function: cMap.prototype.loadMap = function(){ //jquery AJAX call }
Now in the jquery $.ajax({...}); call, I use an anonymous function on the "success:" call: success: function(data){ this.member = data; }
My problem is that inside this anonymous function call I'm trying to call a class member of my cMap class to store the data in from the AJAX call, but it's out of scope. So the JS console in FF/Chrome throws errors about bad value/doesn't exist.
How can I access this class member from inside an anonymous function? Or at least what's a good way to go about doing all this?

Suppose I have the following HTML code:
<div class="one">
<a href="http://jquery.com/">jQuery</a>
</div>
<div class="two">
[Code].....
Basically I want to recognize which <div> tag was double clicked, and hide the corresponding link that is nested within that specific <div> tag.
The only way I can think to do this currently is to basically copy and paste a whole bunch of jQuery code for each <div> tag and it's sub-elements (links in this case).

Is there anyway to trigger an onChange event without actually clicking etc.
I want to trigger it from a method. It sounds silly but I'm taking some code over from another developer and if I could do this it would save me days of re-writing!!!

I have a disabled field which can be changed by using search help showing the select option. After the user selects his wish, the disabled field contains his selection. I need to trigger an event automatically right after the disabled field is changed. This function triggers the event I need:
BBPSCForm_Submit('SC_REFRESH')
the code at the disabled field looks like this:
<input type=text title="`#GL_ACC`" name="`T_SCREEN_ACCLIST-G_L_ACCT[j].name`" value="`T_SCREEN_ACCLIST-G_L_ACCT[j].value`" maxlength="64" size="11" disabled>

I got this problem with live() event.I have used it as follows.
$(".addressDiv span").live("mouseover", function(){
//clickable function here......
------------------------
});
I have used the live() event to trigger the function on mouseover in the dynamically added elements. But the problem i got is that once the live event is called it takes the class of the element and stores. And when the class of that particular element is changed dynamically the live() event does not detect the new classed added dynamically, instead it takes the former class. Live() event does not update the class.

I'm trying to write my first plugin using jquery, it's a form validator, and at a certain point it binds an handler to the submit event for that form:
var that = this;
console.log(this.element);
this.element.bind(evt+"."+this.widgetEventPrefix, function() {
console.log("form event triggered");
[Code].....
the problem is, when I click the submit button of the form, the event is NOT triggered, nor is the form submit, and I do not understand why...
for now, I've found this workaround:
this.element
.find(":submit")
.click(function() {
$(this).closest("form").submit();
[Code].....
but I don't really like it, 'cause it seems so "dirty" to me...
why the form submit is broken and how to "repair" it?

Trying to figure out what was happening in a snippet in the jQuery docs. The snippet I refer to is here , documenting event objects.
The code:
Has me a tad confused. I know that e is an event object that calls keydown event for keycode 64 but what I am unsure of is how it is being triggered. There is no context to it, if you use .trigger() that way is the event called upon the loading of the object? If not when is .trigger() being called?

I cant figure out why a trigger event fires in the following function:
But not in this function:
When using FF 4 or CHROME 10, it seems to work fine in IE9. I have validated that the second function is pulling the proper elements when selecting the toFire variable, but the trigger just doesnt seem to fire. Value is always true or false, never undefined and the Click event that is being fired in the second function is the same that is being triggered in the first function.
