How do I start my literal object as a function like you do when you use the new Object method.
e.g. var fn = function(){ ...code...}
var func = new fn();
I'm trying to achieve this using the literal object method like:
var fn ={
key: ''
}
I've started learning writing javascript objects with literal notation...
Instead of the usual syntax...
The problem is that it's hard for me to adapt procedures which I'm used to within the normal syntax for the literal notation. E.g:
Is this variable global or local? If it's local, how do I declare a variable globally? I also wonder if it is possible to bind events to objects from within the object? And if I'm correct - jQuery is coded this way, but how can they then make use of their selector:
When it is an object defined with literal notation that doesn't have a constructor?
I have the following code which attaches a function to events in x number of comboboxes (x will probably always = 4, but I do not want to hard-code this). I wish to pass the value of i to the function being attached as well as the value of tempData. In other words, I want the parameters in function to be the value, not a reference variable.
In the current example, I am using the hard-coded variable ci. This I want to be replaced by a literal created when the event handler is attached (the value of the loop variable i). Also, notice that I get the filter value in the event handler (assigned to the variable ct). I would like to replace this code with the value of tempData which would also be determined when the evenet is attached (it is the same value in this case, but it keeps the onChange event from having to do this each time it runs).
var props = {
col_0: "select",
col_1: "select",

Below is a stripped down example of code I'm using to count links in a
list. My intent with the ShowLinkNumber() function was to display the
number of the current link. (e.g. click on link 2, and the message "2"
pops up; click on link 4, and you see a "4.")
For reasons I can't trace, my function always displays the last number
in the list. Why does it do this, and can anyone suggest a way to
achieve my goal without adding markup? Code:
I've been banging on this for a couple hours even though I'm sure it has a less-than-five-second fix. Hopefully somebody will glance at it and point out the obvious thing I'm missing.I'm using the onchange event of an html select element to trigger an array prototype function that looks for a value in an array and returns the indices of the array that contain that value, or FALSE if the array doesn't contain the value. For this example, here's the array being set up:
var instids = new Array();
instids[0] = 5;
instids[1] = 6;

Am I able to pass a function literal (at least I think that's what it's called) to a jquery event handler, and retrieved the event details in the function?

I'm using the uploadify jQuery plugin from here: [url] & am having some problems.
Everything is working correctly but the uploadifyUpload() function doesn't appear to be triggering. It is not accessing the add_list.php script whatsoever.
Here is my code from my header..
Code:
It correctly shows an alert box with "Correct" so I know it's getting in there to run it, but it just isn't running.
Shouldn't need to see this, but here is the errorCheck() function if interested..

Lastly this is the HTML code that calls it.. stripped out a lot of uneeded code for clarity.

what is the best way to setup one literal to be the prototype for another?So far I can only think of making a copy into a constructor.
Code JavaScript:
var meths = {
// creates a constructor function populated with a shallow copy of child
// the prototype for the new instance is set to the parent.

Must you use the keyword "new" whenever creating a new object? I was sure the answer to this was yes, but a friend was telling me in this example:
var newDate = new Date();
alert(newDate);
The word "new" is unnecessary and that the system date would be assigned to newDate regardless. Is this true for all objects? Some of the time? Never? I've always understood that "new" was necessary and never questioned it.
I want a specific function to be available to multiple objects.In the script, if it says 'document.Form.Input.value' with 'Form' being the form name and 'Input' being a form element, how can I change this so that I can have two different forms with elements and the function will be able to work for both?

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 have a frame called 'HEADER'. From this frame I would like to innitiate a Javascript Function in a frame called 'CONTENT'. ( function SearchWindow() {....} )
Is this possible and what should the script look like?
parent.content... is as far as I got. But I can't find the right function/variable for calling a function.
The root of the problem is a searchwindow is opened from Header. And in the searchwindow people can click on links... afterwhich the content-frame should change (with an PageID). But I can only get the HEADER frame to respond.
I would like to find all elements within my DOM that begin with "test". Any idea on how I would go about this?

<div id="test1">Blah</div>
<div id="test2">Blah</div>

I'm having a bit of trouble with javascript... I'm searching for a string that starts with another string
code:
for (x in products ){
s = products[x].id.toString(10);
v = "/";
[Code]....
the variables are integers but since i'm searching for the beginning only i turned them into strings...
the problem occurs when I add the it turns out gibberish..
p.s. if there is a faster way to do it without turning the variables to string also would be great to know.
i'll go straight to the point, i have 8 rows and 3 columns, i want to populate each <td> starting from:
row 0 column 0 a value of 1
row 0 column 1 a value of 2
row 0 column 2 a value of 3
row 1 column 0 a value of 4
row 1 column 1 a value of 5
...
row 7 column 2 a value of 24
let's say starting point is at row1 col1:

I have gone through many scripts and functions to find breadcrumbs. While some work, they do not give me the exact function as I need. Due to the layout of my hosting service, I am allowed many websites - however they are all within the same filestore space. At the moment I have 3 small websites that I use for testing and when experimenting with breadcrumbs it includes those websites with the new one I'm experimenting with, meaning Home isnt the homepage of that specific website, but rather the home of my entire file system. For example;
websitehost.co.uk >>username >>website3 >>home >>page1
rather than
home >>page1
Has anyone come across any scripts or functions that allow me to do this - I have hunted around but the majority of the examples I have found produce the problem stated above.
The code I currently have implemented is the code found: [URL]
I have read the code and comments and set the 'domain name' variable to [URL] hoping that it would start at that page, but it does not.
I know you can use the onload statement to start a javascript when the page has loaded, but is there a statement that can start a javascript as soon as the page starts to load?
