Object And Method Can Not Be Found In IE?
Aug 4, 2011
Code:
var testi_box = {
spread: function(num) {
var main_obj=document.getElementById('testis');
$('.bg').stop().animate({opacity:1},800);
$(main_obj).stop().animate({height: 420}, 800);
var objs=main_obj.children;
[Code]...
So, I have this object that is set to fire its method the moment a user hovers their mouse over a particular div on my page. IT works just fine in all other browsers but IE7 or below. When i look at the error in IE it says that testi_box is undefined. But clearly it is defined. So, I'm lost. Is there something that I am missing?

The onload event appears to be firing before all the content of my
window loads or something. In the stripped down example below, my
browser tells me that it cannot find the object "thisThing." What
gives?
<html>
<head>
<script type="text/javascript">
window.onload = document.getElementById("thisThing").style.background =
"red";
</script>
</head>
<body>
<div id="thisThing" style="height:40px; width:50px;
background:blue">
</div>
</body>
</html>

I have a "button" that calls formA, which in turns calls formB, all done through javascript. As a button: <input type="button" value="Preview" onClick="popupform();"> works perfectly. Of course the user doesn't want some ugly standard button. They want this beautiful image to show instead (personally, I think the .gif they made looks like barf, but that's besides the point...sorry). When I substitute
<input type="image" src="/preview/preview_button.gif" name-"preview" alt="Preview Your Item" border="0" onClick="popupform();"> everything works as it should, except the original form, the one that has the button/image on it, becomes a 404 Object not found. The popupform() sets a bunch of cookies, and calls formB. FormB is a .php which reads the cookies and does some other stuff. Not that it should matter, but I am running everything locally in Vista using the XAMPP Apache Friends Edition and going through localhost (because formB is a .php)

I am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.
My code is as follows;
Code:
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?

I'm working on a drag and drop HTML editor, in which blocks can be positioned. I need to build a controller which listens to mouse events and takes appropriate action (a state machine). The system is built using prototypes and objects. The Controller class looks like this (I removed some methods for simplification):
Code JavaScript:
/**
* Creates a controller for a document
*/
function Controller() {[code]....
The method 'handleMove' is entitled to handle a mouse move on the overlay. Because the 'this' keyword would not point to the Controller object I've written a wrapper according to the W3C EventListener interface (http://www.w3.org/TR/DOM-Level-2-Eve...-EventListener). This wrapper holds a reference to the object in which the method resides that's handling the event, so that the important 'document' attribute can be reached. This document holds the document that is being edited (it's of a custom type, and not to be confused with the document as in document.body)
The problem I now have is as follows. IE doesn't seem to be able to work with event handlers following the EventListener interface, but just functions. I need to get the object's reference there as well though, but this can't be done using an anonymous function, as at the moment it will be run it will be in a different scope, and not be able to reach the controller any more.Just using a global holding that reference variable, a method I used before, is not sufficient, as there may be multiple instances of the editor running on the same page.I have no problems in FFox, Opera, and Safari. Just IE because it uses an alternative event listener model.

I 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?

$.getX();
$(function(){getX()});
$().function().getX();
$("myHtmlObj").click(function(){getX()});

This is the first time i'm really using javascript objects (well the first time i've written my own one) so the problem is probably a very simple one...
I've got this:
Code:
When i change the country from the dropdown box i get an error "hometown.setCities is not a function" but the thing is that i can call this in other ways eg from the address bar (javascript:hometown.setCities()) and it works perfectly.

I'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?

I'm trying to write a little script that disables the submit button on a form, changes the text of the button, and then submits the form.
Can anyone tell me why this works ok:
<input type="button" value="Submit" onClick="this.disabled=true;
this.value = 'Submitting...' this.form.submit();">
But when I try to make a function it doesn't work:
<script language="JavaScript">
function DisableButton(b) {
b.disabled = true;
b.value = 'Submitting...'
b.form.submit();
}
</script>
<input type="button" value="Submit" name="submit"
onClick="DisableButton(this);">
When I try this the button text is changed and the button is disabled, but the form doesn't submit. In IE I get an error that points to theline that says:
b.form.submit();
and the error:
Object doesn't support this property or method
What's the difference between doing this code directly in the onClick event and doing it in a function?

I am trying to use some really simple jquery in a rails 3 app. I am trying to get a function to run whenever a rails 3 js callback is fired, the function is to add or remove css classes from link elements. But so far I keep getting errors in the console (chrome) stating that the object defined by my css selectors doesn't have the addClass and removeClass methods.Here is my code:
$(function($) {
var resetArtistTabStates = function () {
$("#artist-tabs li a".addClass("current"));
[code]....
The ajax:success event come from rails.js jquery file, which contains the following:
callRemote: function () {
var el = this,
method = el.attr('method') || el.attr('data-method') || 'GET',
[code]....

There's something I can't understand. If I do:
Why does jQuery return elem1 and not the created element ? Returning the created element does much more sense to me since:
a) I already got a reference to elem1 if I need to do further manipulation.
b) I got a references to the 'div' element I've just added.
The way jQuery does it, I'll never get a references to the element I've added.
Can anybody clarify this for me? Is it a 'jquery way' to work this?

I'm trying to send my array object through ajax using the jQuery .get method, but when it sends, ids show up as multiple parameters and I'm not sure if that's the way to do it.
Here is my code:
var val = [];
$(':checkbox:checked').each(function(i){
val[i] = $(this).attr('id').substring(6);
});
$.get("/assets/ajax/pm_change_status.php", { s: sess_id(), 'ids[]': val } );

I am creating an application that uses as much Object Oriented code as I could (mostly to learn it).
I have an object called 'photo' that contains two Image() objects 'fullImage' and 'thumbnail'. All is fine and dandy, I can read the thumbnail and the full image, and their associated properties just fine.
But what I can't seem to do is make the thumbnail's onclick event refer to one of the object's methods.
Here is a greatly simplified version of the object's code.
Code:
So, the thumbnails div gets populated with the thumbnails fine. But for the life of me, I cannot figure out how to make the onclick call the photo object's "editPhoto" method.
Will the way that I am creating the objects using the same name for each one, result in only the last one created being accessible. If so, do I need to create an array of objects so I can uniquely identify each one?

I am trying to preload some sounds for a website I am working on... Originally I used the embed tag but that caused problems in Opera and did not validate... So I've switched to the object tag which now works in everything except IE8...
<object id="sound_lock" class="embedded" data="sounds/iphone/system/iphone_sound_lock.wav">
<param name="autostart" value="false" />
</object>
I had to put in a class to hide the sound files because tey were appearing with controls in Opera...
.embedded { visibility: hidden; }
Lastly here is the javascript code that plays the sound when required... Works in latest FF, Opera, Safari and Chrome but not in IE8... IE8 generates an 'object doesn't support this property or method' error...
var thisSound=document.getElementById(soundObj);
thisSound.Play();
I'm assuming this is because IE8 can't get the id from the object tag but can't find a work around... I want to make sure all the code validates appropriately so I am trying to avoid the embed tag..
