Does anyone know if it is possible to find out what element in the DOM made a call? Let's say I have a table and every cell has an onClick event attached to it. Is there a way to figure out what particular cell was clicked in the DOM? I know it would be easy to use ID's and just do an getElementById(), but, the ID's are generated from the system and I can't ever be sure what number any particular cell is, so I need another way if possible.

What I am coding now is a piece of a much larger project that I am, for the moment, developing on my own. This code, relatively useless on its own, is essentially practice or proof -of-concept. Much of it will probably be used in the larger project. If at times, it seems that I am using a cannon to kill a fly, this is why.
Additionally, I do not claim credit for all the code here. Some of it is copied from other sources. I have studied it, understood it , then modified it appropriately, making it my own.
However, the code is broken. I have tested it on Internet Explorer 9.0.??? and Firefox 4.0.1. It breaks in both browsers. I have previously tested it in Chrome, but not recently. On IE I have used the built in debugger, and I have been using Firebug in Firefox. I have also used the debugger at [URL] quite frequently. JSLINT returns some 'Bad Type' errors regarding 12 lines in the html body, each having the structure: <td><input /></td>. I can find no explanation for the 'Bad Type' errors. Otherwise, according to JSLINT, the code is fine.
The predecessor to this code worked fine. I had been using inline event handlers (onblur and oninput) that called the doMath function when one enters data into the table. The values are then averaged and summed. All this is extremely basic. The problem began when I removed the inline event handlers and began to use window.onload (I believe I am using document.onload now, but the problem has not changed.)
I have adopted Douglas Crockford's 'walkTheDom' recursive function to find all tags with a particular class name. I would like to assign every element in the array returned by this function an event handler.
This is the problem: This script simply cannot find the body node of the DOM ( and, seemingly, none of its child nodes either). Initially I tried 'document.body', which failed. I then began with 'this' (essentially 'document') and tried walking the DOM to get to it ('body') eventually. This, too, failed. I tried array index notation to refer to it(I forget the specific syntax), and most recently, I've given it ('body') an id and referred to it directly using 'document.getElementById()'. These most recent attempts also failed.
After hours of figuratively bashing my head against the wall looking at code and probably even more time doing research online, I am extremely frustrated. As often seems to be the case, my problem is probably simple
I have included most of the code, even though it is a little long. This way you may easily copy the code and reproduce the problem yourself. I do not often post to forums, and, more relevant, I have no idea where the error may be located.
Potential problem areas are in RED.

The .find() method does not seem to match on input fields by using a class. The ti This problem seems to be only visible on input fields. The following is a demonstration of the issue:

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 have an iframe that includes a button:
<input type="button" value="close this window" onclick="window.close();" >
I would like to detect the iframe close event from the parent window, I
was using this code but I did something wrong because the temp function
is fired every time the parent page loads:
function temp(){
alert('the iframe was closed');
}
function setup(){
var myIFrame = document.getElementById("iframe1");
if (myIFrame.addEventListener) {
myIFrame.addEventListener('onclose', temp(), false);
}else if (myIFrame.attachEvent) {
myIFrame.attachEvent ('onclose',temp);
}else{
myIFrame.onclose=temp();
}
}
window.onload=setup;
how can i know the original element that raised the event if that event is propagated up the tree ?
View 6 Replies View RelatedAs far as I understood, stopPropagation() is supposed to stop events bubbling 'up' though the element tree (through parent elements). Eg. If I use stopPropagation() on a click event on an anchor element in a list, the event would not be triggered on the list. In my code I have a popup div, that needs to have stopPropagation(), as a click on the document (everywhere other than the popup) will hide it. When I add an element to the popup that has a live click event, the live click event is never called, even though it is a child element of the popup. Shouldn't the live click get called first? If I remove the stopPropagation all is well.. some code:
$('#a_test_link').live("click", function(e){
e.preventDefault();
alert('done!');
});

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:
Is there a generic way to fire an event when the state/value of a checkbox is changed by another event - i.e. not a user action. In this scenario, I have a set of checkboxes with a "select all" checkbox. I have the code written such that checking or unchecking the "select all" checkbox updates the state of all of the checkboxes below.
The extra requirement here is that some of these checkboxes have "children". So, when you check one of these, its children are automatically checked as well. So, what I need to do is check the main "select all" checkbox, which would then check all of the immediate children, which would then check all of their immediate children. I tried both an onchange and onclick event, but neither seem to be firing.
<html>
<head>
<script src="/scripts/jquery/jquery-1.3.2.min.js" type="text/javascript"></script>
<script>
[code]....
look at this script :
$(function(){
$('input').bind('keypress',null,b).bind('change',null,a);
});
function a(){
[Code].....
this script bind both keypress and change of the text box to functions b and a. at keypress event handler if user type a char on input box the value of input box change to x and the user char discarded. In this case we expected to run the onchange (change) event because the textbox value is changed BUT this doesn't happen.
I have an object that has a click event I'm trying to trigger. However in the click event I have the following if statement:
if(event.button != 0){return true;}
This if statement allows right clicks to go through and activate but it also prevents me from triggering the event. Any ideas on how to prevent this? If I remove the if statement from the first click function everything works as intended.Here's my example code based off of the trigger event examples:

currently on our site we have and expanding <div> that responds to both the onmouseover and onmouseout events. It works wonderfully.
The UX people now would like the expanding <div> to open with the onclick event and then as soon as the mouse leaves the expanded div, it would close. I have tried using the onmouseout event in conjunction the onclick event but it does not work (the div persists).
The DOM Level 3 specification has a section (1.2.2.2) that talks briefly about "groups" of event listeners. What does this mean? Is this similar to attaching event listeners with a namespace, as in jQuery: "event.my_namespace"?

All i want to do is have the onclick fire when mouse clicks on the background only. Currently it fires when either element is clicking.( it fires through the foreground element)How to i prevent this while maintaining a child parent positioning relationship?
I want to be able to prevent an event from running while another is in progress. For example, on this page [URL]
if you click "Next" a number of times quickly, it stores all the clicks in a queue and will continue to run all the clicks way after u finished clicking, how can i prevent another event being added to a queue while an event is running?
Code:
<script ... javascript >
document.onmousemove=(hit_test);
function hit_test(evt)
{
if (!evt) evt = window.event;
if (evt) document.getElementById("a").innerHTML = evt.clientX;

I create buttons from an array of objects that such as:
buttons = [{ text: "button 1", action: 1}, {text: "button 2", action: 2}];
I then loop thru the array to assign the text and bind the click event after having created the buttons with IDs of "button_<index>".
for( var index in buttons ) {
$("#button_"+index).html ( buttons[index].text )
.click( function() { clickButton( buttons[index].action ) } );
}
The text appears correctly in the button, but every button defined only fires the list bound click, in this example the action equal to'2'whether I push "Button 1" or "Button 2".My actual case has four buttons, all firing the event for the fourth button.I've tried not chaining the .click(), going thru the loop twice once for the .html and once for the .click, neither of which made a difference. If I hard code each button .click, it works fine.
