OnDrag Handler In FireFox?
Oct 20, 2005
I am trying to handle my mouse movements myself in my JavaScript
application which is ok except for the following problem.
If I happen to click on an image and then move the mouse, the "no-drop"
icon appears as the browser is starting to drage the image url
somewhere. When this happens, I no longer recieve any mouse events in
my JS app. This can be prevented in IE by adding an event handler for
the onDrag event that simply returns false. This prevents IE from
continuing to try and drag the image and instead it continues to send
mouse events.
However, I cannot find a way to do this in Firefox. Can anyone help?

I am successfully using this code to cause an event to fire when the user clicks inside any of the text inputs in my form:
Code:
govindaAddEventHandler(document.getElementById("input_" + arrWhichFieldsFilterable[i]),"click",getMouseCoords); // govindaAddEventHandler(obj, eventName, handler)
...which relies on this:
Code:
function govindaAddEventHandler(obj, eventName, handler) {
if (document.attachEvent) {
obj.attachEvent("on" + eventName, handler);
[code]....
The problem occurs when I change it from an on"click" event to an on"focus" event. In the latter case (onfocus) it does not work on Firefox, but only in IE8. Why is that? How can I add an event handler for onfocus in firefox?

I have added an event listener to a LI item in the DOM:
liNode.addEventListener("mouseover", mouseOn, true);
The mouseOn function:
function mouseOn(e) {
// Test for IE or Firefox
var e = (!e)?window.event:e;
var yPos;
[Code]...
I would like to pass in another parameter to the mouseOn function in addition to the event that is passed in automatically. Is there a way to do this?

I'm seeing surprising behavior, consistent across Opera, Firefox, and IE.
An event handler is changing the value of an element, and there is apparently
no Change event being generated for the element. A simple illustration is,
make an INPUT element with an onchange; type in a new value, the Change
event handler is called. But make a button whose Click handler changes the
value, and the Change handler does not get called.
It appears that events are not generated while an event handler is running.
Can this be true?

How can I interrupt the enter key so it won't trigger unwanted events on my
web page? I have tried this:
var defaultEventHandler = obj.getEvent("onkeydown");
var myEventHandler = function(event){
if(event.keyCode==13){
alert(obj.getProperty("selection/index"));
}
else{
defaultEventHandler.call(this, event);
}
}
obj.setEvent("onkeydown", myEventHandler);
But it won't even enter the function.

When using variables in click handlers, is there a way to use the value of the variable when the handler was setinstead of run? For example:
var links = new Array;
for (i = 0; i < 5; i++) {
links[i] = document.createElement('span');
$("body").append(links[i]);
[Code]....
All five of the "Click here!" create an alert with the number 5, which was the last value iwas. How can I have each click function use the value of iwhen it was looping through (0, 1, 2, 3, 4)?

I have simplified the problem - see image.[URL]I instantiate object obj1 which inturn instantiates subObj1. subObj1 is a slave to obj1. obj1 registers a handler function called method1 with subObj1 so that subObj1 can tell obj1 when it has finished.For example: call subObj1.subMethod2() to get the sub object to do something.subObj1 calls subMethod1 when its finished with its task, which inturn causes method1 to be called.
If I call method1 directly from obj1 'this' refers to obj1.However when method1 gets called by the subObj1 through the event handler mechanism,I find that 'this' has been changed to refer to subObj1.This is a problem as now method1 has lost all connection with its object obj1.If I define method1 within the 'Class1' function, I can get it to work if I use the 'var me = this;' trick, but if you have lots of methods within Class1() with further nesting this can get a bit hard to read.So, can someone tell me how to deal with 'this' changing. I.e. I want 'this' to refer to obj1 within method1.
<html>
<body>
<script type="text/javascript">
[code]....
On another note, there seems to many ways of defining methods (e.g using 'prototype' etc etc) and I gettting sick and tierd of a 'trial and error' approach to get things working. Can anyone recomend a good resourse that sets out the best way to design with javascript so I dont keep running into these issues.

I got following document:
When you click the main button, will one of the six images get a background image, and you can then press the image with the background image, and get your "reflextime".
But it won't work. When I press the image, were the new background image has shown, you can click on it and get your time - why?'

I'm having a problem with the returning a php variable from my ajax php handler.
I call the handler...
if(ajaxRequest.readyState == 4 || ajaxRequest.readyState == 0){
var ajaxDisplay = document.getElementById('ajaxDiv');
var refreshID = "";
var timeout = "<?=$timeout?>";
ajaxDisplay.innerHTML = ajaxRequest.responseText;
//Change Refresh Timeout Based on Remaining Song Length
refreshID = setTimeout("DoRefresh()", timeout);
DoRefresh() function is the ajax function. What am I doing wrong?

I try to add a function to be triggered also within an event (which already has a function). I coded it, unfortunatelly one line of the code should be different for IE and Moz. I try to find a common way without using a browser detector... Any ideea? The red line works for Mozilla, the blue one for IE:
function addFunc(){
var e = document.getElementsByTagName('*');
for(var i=0;i<e.length;i++){
if(e[i].getAttribute('onclick')||e[i].getAttribute('onclick')!=null){// Moz || IE
//var f = new Function(e[i].getAttribute('onclick'));
var f = e[i].getAttribute('onclick');
e[i].onclick=function(){f();otherFunction()}
}}} Code:

I need to convert
<div onmouseover="mousehand(event,'outerjob123');">
to a javascript call, ie.
x = document.createElement("div");
id = 123;
x.onmouseover = mousehand(event, 'outerjob' + id);
However, the syntax doesn't seem quite right, can someone enlighten me?

I modified a particular page in the following way:
I ran an init function on window.onload, which iterated thorugh the checkboxes on the page and assigned an event handler function - let's call it validate() to each checkbox.
I tested it in the big 5 browsers and ran into a strange issue in I.E. only -
let's say there are the following checkboxes code...
When I click on "box1" the function is not called. When check "box2" the function is called but by "box1", when I click on "box3" the function is called by "box2" and so forth...

I'm finishing up the front-end of an events management application, but I'm running into a problem with my javascript.
Here's the scenario: I have the php application returning all event details into a JSON object.
The object structure looks like this:
Code:
Each event title listing on the calendar grid is assigned "#" plus the event's ID for it's link, just for testing purposes--no problems.
Eventually, I want the user to get a yui container (modal) with the event details, but when I add the onclick handler to the links, the id that gets passed for each of the links is the same, 60 (which is the ID of the last iteration in the loop).
Here is my code:
Code:
I've tried using the var keyword to localize the id, but that produced the same problem.

I'm writing a base class for a project and one of the class's prototypes encapsulates cross browser event listening. One point of confusion is that removeEventListener requires that you know the handler. I don't have this info because I'm creating anonymous functions, so how do I do it?Here's the code:

Our project has thousands of web pages.
We have certain default chores we would like to occur as part of the
onload handling for all of these pages.
Rather than modify every page to say
window.attachEvent("onload",defaultChores);
is there some neat way to perhaps tap into the page-loading process so
that the above attachEvent call gets performed implicitly ?
Perhaps this involves some sort of server intervention. That is a
possibility for us, as we have access to the server as well (it's
typically a tomcat server), although admittedly if this is the only way
to do this, then this discussion should quickly migrate out of the
javascript newsgroup and into some sort of web server one.

I'm creating a drop down menu so that when a user clicks on the drop down arrow and then hovers over one of the options, a bubble comes up and does a validation. The thing is that everything works fine in Firefox, but not in IE or Chrome. The problem is that the .mouseover() function doesn't work on the <option> tags in IE and Chrome, but it works fine in Firefox because apparently FF is the only browser that supports it.

I have a form with a text box. As you know, if a user has previously entered data into that text box from the same machine, then a dropdown list appears in the browser showing previously entered values. That's fine; however I have an OnKeyUp event on this box so if a user selects from the dropdown list then the event isn't triggered. Is there any way to recognise this action as an event? None of the normal event handlers appear to do it.
