I have many forms on a page. When a user click on a new or upate link, releated forms shows up in a dialog box and i validate it .

I am trying to convert some of my javascripts into a class and am
running into difficulties which i think are related to variable scope.
Basically I have a constructor function for a calendarInput class that
takes 4 parameters, the first is a reference name/number for this
input. I also have some functions for importing my PHP classes into
Javascript using AJAX (properties only. still trying to get methods
working but that's another story!). The relevant function is called
call_object_method(classname, methodname, createparams, methodparams,
post, callbackfunction). This creates an instance of the specified PHP
class using the parameters in createparams. It then calls the
specified method using the parameters in methodparams. The result is
passed back to the javascript function specified in the callbackfunction parameter (ie the value of xmlhttp.onreadystatechange is set to callbackfunction before xmlhttp.send() is called)
The function i am trying to fix is called show (x,y) which creates the
html for the calendarInput and displays it at co-ordinates x, y.
So, my code is as follows:
function calendarInput(calendarid, target, displaytarget, value)
{
this.calendarid = calendarid;
this.target = target;
this.displaytarget = displaytarget;
this.value = value;
this.show = function(x, y)
{
<!--// bunch of init and prepping code. includes creating
createparams and methodparams arrays //-->
call_object_method("cms_calendar", "getcalendarview",
createparams, methodparams, false, this.showcallback);
}
this.showcallback = function()
{
alert(this);
<!--//code to create html//-->
}
}
I know i've cut out most of the innards of this. This is because I
have already tested these functions and had the calendarInput working
outside of a class, hence am pretty sure that this is ok (plus it runs
to almost 1000 lines these days!!). My problem is that when I call the
show method, the alert on the first line of the callback function
returns the function showcallback instead of (as i was expecting) the
instance of the calendarInput object. Whilst this kinda makes sense I
can't figure out how to reference the Object instead. I have tried
'this.parent' but this returned undefined. I have tried changing the
way i reference the callback function (ie the final parameter of
call_object_method) but no joy.

so, I can pass a value from a select list to another function which then decides which function to call, but I want to cut out the middleman, and make the values the function calls, and call them directly on the onchange... I imagine something like this:
<select id="select" onchange="this.value">
<option selected value="function1()">Funtion 1</option>
<option value="function2()">Function 2</option>
<option value="function3()">Function 3</option>
</select>

I have two jQuery scripts running on the same page. One of them dynamically assigns height parameters to the wordpress page. The other is a slideshow script which makes images transition from one to the next in a slideshow.When the slideshow is inserted into the wordpress page, it works fine, but in IE7 there is extra page height whenever there is a slideshow on the page. In other browsers it is fine, and on other pages that dont have a slideshow the page height is fine.Looking at the source code, it seems that the dynamically assigned div height paramaters that are injected into the slideshow divs by the jQuery slideshow script are getting involved in other divs on the page, influencing their height.It seems that the slideshow script is interfering with the page height script. how can I make it so they dont entangle? Here is the page height jQuery script that assigned dynamic height to the "art-content-layout-row" div (the div that controls page height)
Code:
/* begin Layout */
jQuery(function () {
if (!jQuery.browser.msie || parseInt(jQuery.browser.version) > 7) return;
[code]...
When looking at the html source in the page, the slideshow script inserts this jQuery unique number beside the dynamically added div parameters in the slideshow divs like this:
cyclew="666" cycleh="555" jQuery="130236363678267"
It turns out that this same unique number is assigning itself to the art-content-layout-row div which is supposed to be controlled by the other script.I am wondering if the fact that these unique id numbers being the same is causing the issue, as though the system is thinking that these two scripts are somehow the same one?Both scripts are in different directories and called separately in the page footer.

If slideToggle()'s parameters were expanded to include a separate callback for sliding up and sliding down. Or for backwards compatibility, perhaps include an optional boolean parameter in the callback to more easily discern between a slideUp and slideDown operation.

I am struggling to find examples on the web that implement Javascript
callback functions of an embedded Real Player.
There are lots of examples for Visual Basic, but I couldn't find any for
Javascript.
I am looking for any basic example.
For example, showing a javascript alert when a Real Player error is
triggered. (with examples for both Netscape/Firefox and Internet Explorer)

I am writing a small module which will have several different aspects to it, all based around ajax calls. I want to allow the main ajax functions i.e beforeSend, success, complete etc (I am using jQuery) to be customizeable.I currently have an options object in the module which can be extended with an options object passed to an init function. In here, I am passing a 'callbacks' object with nested ojects for each different type of action as in...
var insertCallbacks = {
before : function() {
},
success : function() {

for some time I always found a workaround for this kind of problem. But somwhow, it feels wrong. So I'd like to know, if there's a common way to solve something like this[code]...
I'm defining the function and if the value of 'obj' hasn't until the function really gets called, this can work. But it just feels so wrong do have always global variables just to access them inside of a callback.[code]...

I use the getJSON request to fill a select (with cities names) after the user have choosen his region.
I paste some code:
The problem is that callback is never called. I used firebug and i have seen that when i change region the getJSON function is called and my script (python) return this JSON:
Why my callback is not called? I can't even get the alert ('callback time!'). I thinked that my json could be broken, but firebug net console read and parse it very well, so i think is valid JSON.
I also tried to split up the function declaration from the getJSON request, but it's no use.

Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.

I prefer to keep all my scripts in an external '.js' file. I am currently loading the external '.js' file from the header. Problem is I would like to declare a global variable in the external file, but I keep getting an error about the object does not exist.
Can someone tell me where or how to declare a global variable in an external file that is available after the page is loaded.

can anybody put forward a sensible argument javascript's behaviour of
creating a new global variable whenever I assign to a previously undeclared
variable. I can't beleive this is just for the sake of convenience (surely
we learned this much from basic).
here's my proposal: all "global" (document scope) variables must be declared
by 'var' outside a function block.
failing that, does anyone know any patterns or tricks I can use to make sure
I don't create a new global variable when I accidentally misspell a variable
name?

How do i declare a default value in a function? I have a simple function
function color_input(id,token){
if (!empty(token)){
document.getElementById(id).style.backgroundColor = '#2A2A2A';
document.getElementById(id).style.color = '#DDC58C';
[Code]....
You will notice that the #2 parameter is missing in the html call. Sometimes i don't have it to send. in PHP i would just set the functions second param like token=''
function color_input(id,token=''){}
How do i set a default param in a JS function?

How do i declare an empty array?
I need to iterate through a group of arrays and search for a user-chosen word every time.
The problem is i can't declare how many array elements will be needed, such as: new array = (12), because some words inside my arrays, occur more than others.
So i need to decalare an empty array with x number of possible values.

Well, I've been working with JS for three years and have a great experience here. But! I still have no really acceptable answer to the following
question:
What is the principle difference between declaring methods/properties
in the constructor function body and via prototypes.
Are there any real GURUs? Let's discuss the issue.
