Mozilla - Access Event Object ?
Jun 15, 2011I have a JS method register in a TD element as below:
Below is the Js Method:
The JS method works fine in IE but in mozilla throws an error that event is undefined.
I cant pass the event object from HTML while registering the method as HTML is written by someone else and I cannot change that. All I can change is the JS method.
How can i access the event object in JS method.
The 'event' Object And Event.clientX
Oct 29, 2004Code:
<script ... javascript >
document.onmousemove=(hit_test);
function hit_test(evt)
{
if (!evt) evt = window.event;
if (evt) document.getElementById("a").innerHTML = evt.clientX;
}
</script >
which works nicely;
I understand that the 'event' object is a globally accessible object in IE but not in Mozilla; instead in Mozilla the 'event' object is sent, by default, as the first parameter in a call to a function; is this true? ...

My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?
JQuery :: Calling .trigger() On A Object Outside Of An Event
May 12, 2011Trying 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?

JQuery :: Propagated Event Object Is Missing Properties?
Aug 30, 2010This object was passed to my click event handler. Why are so many properties missing? The click event came from an <a> in a <li>, propagated down to the <ul> on which the handler was set.
If I click on the <ul>, the event object looks "normal".

JQuery :: Creating New Element /w LIVE Event By Passing Object Map?
Apr 4, 2010So, I read about the new method of passing an object map containing element properties when creating a new jQuery object (as discussed at the bottom of this article). The article says that it supports ALL events, but only gives examples of simple events that require no parameters. I'm trying to implement a live event using the following and can't get it to work:
var link = $('<a />', {

JQuery :: Object Expected Error In IE - Ready Event Disappears
Nov 21, 2011Have been hammering away at this problem for a couple of hours and found that the 'type' attribute of the jQuery script files is set to 'application/javascript'. This works in Firefox but not IE. When changed to 'text/javascript' the IE error on $(document).ready event disappears. As yet no apparent side effects have occured. This is the only scenario where I have seen 'application/javascript' ever used so why this instead of 'text/javascript'?
View 1 Replies View RelatedJQuery :: Object Loses Event Binding In Internet Explorer?
Feb 26, 2010I am working on a script to allow the user to click on an image to turn table header locking on and off. Everything appears to work fine, with the exception of one quirk that is occurring when I run the test page in Internet Explorer (7, in this case). If you click on the icon once to turn on header locking, it works. If you then click the icon again, it turns off header locking, as it is supposed to. But after that, you can no longer click on the icon. It is as if it loses the event binding. I am not removing or in anyway creating a new instance of the icon (although I did try using live() instead of click() just to be safe). Also, if I run this same page in Firefox, I do not have this problem. You can see the example page and view the complete source at [URL]

Object Method As Event Listener
Oct 16, 2006I want each instance of an object to be able to listen for input events.
When the event occurs, a method of the object should be called, such
that "this" is in scope and refers to the object instance.
Is this possible? Example:
function MyConstructor(element)
{
//element is some HTML element
this.addListeners(element);
this.foo = "Bar";
return this;
}
MyConstructor.prototype.addListeners = function(element)
{
element.addEventListener("keypress", this.doSomething, true);
}
MyConstructor.prototype.doSomething = function(e)
{
alert(this.foo.length); //Error: this.foo has no properties
alert(this);
//shows the HTML element that triggered the event
}
Is there any way to get "this" to refer to the object in the event listener?

Onclick Event For OBJECT Element In IE
May 3, 2006I can't set onclick event properly for OBJECT (flash) element properly. onclick just don't bubble outside flash object. Could this be caused by AS getUrl() function?
I tried to attach thru .htc, tried transparent IFRAME on top of object, etc. Nothing seems to work.
Is there any reasonable way to attach onclick to OBJECT element or flash movie by using JS or plain HTML? Should I do something for event bubbling?
Reference To The Object An Event Was Attached To?
May 30, 2006If I have several links with onClick events pointing to the same function, how can I get a reference back to the link that was clicked?

View 5 Replies View RelatedBinding Object Method To Event
Jun 24, 2002I'm trying to build a Validation object, where you pass an object id and event name in the constructor. Then, you call an add_rule method to add validation rules. The constructor code looks something like:
function Validation(id, event, ...)
{
this.object = document.all[id];
this.event = event;
var obj = this.object;
obj[event] = this.validate;
}
So the actual validation function is dynamically bound to the appropriate event. The problem is that when the validate method is called, "this" no longer refers to the Validation object; it refers to the object to whose event it was bound. So, for instance, in the following code, the validate function's "this" refers to frmSubmit, not objValidate:
objValidate = new Validation ("frmSubmit", "onsubmit", ...);
Of course, I need to refer to the actual validation object's properties, but I can't figure out how. Any suggestions?

Object References When Using Bound Event Handlers
Feb 27, 2007THE QUESTION: How do I get a reference to my Object when processing an
event handler bound to an html element ?
CONTEXT:
Sorry if it is a bit long.
I am developing a JS calendar tool. One of the requirements is that the
calendar will need to display a varying number of months (1..3)
depending on the calling page. Imagine 1, 2 or 3 calendar pages side by
side as required.
I have built a grid object that will contain one month's dates with the
day names at the top. The calendar object inherits the grid object as an
array of "calendar pages" - one grid per month and the calendar provides
the content for each grid. I will use the grid object for another
completely different object later and so I want to use good OOP
encapsulation. The grid is a table generated on the fly and is "dumb" as
far as what it is used for.
I have attached an onlick event to each cell of the grid. Using OOP
priciples I want the calling program (the calendar object in this case)
to provide a function to handle the click and the grid object will
provide to the calendar the row and column of that cell as well as the
grid number (so the calendar can work out which date was clicked since
it knows what the data means and the grid doesnt). Code:

Getting An Object Instance Reference In An Event Handler
Jan 3, 2006I've been playing around with JS for a while, but I've not ever found fantastic learning resources. I'm comfortable with other programming languages, so I'm very interested in OOP programming for JS, and I've started to use tools like the Prototype library for that purpose.
However, one problem has consistently caused me problems whenever I'm writing a JS Class. How can I get a reference to the specific class instance from inside an event handler that I create with a class method. Let me give an example of what I want to do:
(This code is using the Prototype library...)
myClass = Class.create();
myClass.prototype = {
makeLink: function(obj) {
// Out here, "this" refers to the instance of the myClass Class
obj.innerHTML = ''
obj.onclick = function() {
// In here, "this" refers to the clicked on element.
// How do I get a reference to the instance of myClass in here?
}
}
Here's the best way that I know how to do this right now. It seems to work in Firefox alright, but doesn't seem to work in IE:
myClass = Class.create();
myClass.prototype = {
makeLink: function(obj) {
obj.innerHTML = ''
self = this; // Save a reference to class instance as "self"
obj.onclick = function() {
// Self is evaluated to instance reference at time of assignment to onclick
self.linkClicked();
}
linkClicked: function() {
// Do something useful here
}
}
Is there a more elegant way to do this? I could just create all of my event handlers for objects outside of the class in procedural code where I already have a reference to the class object, but I like to wrap these things up inside the class, because sometimes they get significantly more complicated than this very simple one. Anybody have any solutions? This has to be a common design pattern...

Capturing Onclick Event For Flash Object?
May 7, 2010Probably covering well trodden ground here but so far I haven't found any reliable solution and "it can't be done" seems crazy. Here goes:I have some Flash and non-flash banners that are to be embedded into my page - all managed by a simple CMS. The Flash movies are not created by me as they are for 3rd Party advertisors, and I do not want to be doing any Flash programming myself as it's not my thing and I don't have the resource to do it. As with the JPEG/GIF files - I just want to be given the file and then embed it.
What I want to do is produce some MI based upon when the various banners are clicked - things like how many clicks and who clicked them (users are logged into the web site so I can track them). Simple enough for JPEG/GIF banners capturing the onclick event but for Flash it seems that the Flash movie prevents (or overrides) the onclick event from registering.This seems crazy! I want my application logic (in this case logging user activity) to be independant of the media content - especially as I am not in control of the media content.Googling and experimentation shows that for IE I can seemingly use "onfocus" but this is not very satisfactory and of course I need a cross browser solution.This seems like such a simple concept that at the time of specifying the requirements it didn't occur to me that this might not be possible.... but it seems that I may be wrong!
