JavaScript - Function To Read-in External "xml" Datafiles On For Loop

I'm building a t-shirt shop whose interface includes a gallery of designs in an IFrame. When the user clicks on a design, a dedicated page is loaded into the IFrame which shows all the available products associated with the design the user clicked.

I've put each design's image and associated page as the first and second elements of a nested array, and am using a for loop to then load all the images into the page that's shown in the IFrame when the web-site loads. It's looking beautiful, but here's the rub I've been stuck on for two days now with no solution in sight...

The array, "designImages", has 37 elements (ie. designImages[0]... designImages[36]). When I click on a design image on the page, any design image, the browser (all browsers, so I can't blame Microsoft for this one ), loads the page for design #36. I've tried all sorts of things, but still cannot tell if the issue is because the dynamically generated divs are being reassigned the value [36] after the for loop's executed, or if the div id's are okay but somehow the code is rooting for [36], the last element of the array anyway.

I need someone's help in enabling a click on #4 to load the page for #4, etc, etc. Here's the code below.

Thanks.

Code:

/* designImages[x][0] = the image source on the page;
 * designImages[x][1] = the destination url on clicking the image;
*/

		var designImages = new Array();
		designImages[0] = new Array ( "Assets/DesignImages/Img00 - CosmicCircle.png" , "ProductGalleries/Img00.html" , "Cosmic Circles" , "Mark Lavin");

Hi, this is the first part of a long code and I have three questions wondering if anyone could help me..
1. What is the benifit of having the above code with "window.onload" and "for loop" and loop through the forms if I only have ONE form in html?

2. What is this line of code "document.forms[i].onsubmit" saying? Does it mean "Execute function() when submit button within form[i] has been pressed?"

3. function() - Does this empty function mean "run every following function below"?? Thank you!!

I am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt".
Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from:
[CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want
prefs = new gadgets.Prefs(), // Pulls from the user's preferences
yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences
title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc.
[CODE]
Thank you so much! I seriously could use as much help as possible!

Hello,
recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags!

I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)?

Any comments?

Hi all, I'm having a bit of a problem..

I need to disable the submit button on body onload, and i need to re-enable it when "i agree" is checked.

the problem is, it wont do this..

it literally stays disabled, even after check mark..

Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games.

Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges).

I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site?

Regards,
Steve

ok so

Code:

document.write("Goodbye!");

works but I put ^ that inside a function

Code:

function SayHello ()
(
document.write("Goodbye!");
)

and it stops working? I know the function call works because when I place some code to display an image in SayHello function, it displays the image.

I tried to explain it pretty well in the comment tags, thanks!

I'm trying to get the following function working

Code:

function jump(document_root, mode, cat, id, qs)
{
    var response = confirm("Are you sure that you want to completely delete this record");
    if(response)
    { 
        var url = document_root+"/"+mode+"/"+cat+"/"+id+qs;
        window.location(url);
        return true;
    }
    else
        return false;
}

It called with the following

Code:

<a href="" onclick="jump('/tradedoubler_admin/web', 'Pages', 'Delete', '011' ,'');">Delete</a>

But the redirect isnt working i get the following error :

Code:

Error: uncaught exception: [Exception... "Cannot convert WrappedNative to function"  nsresult: "0x8057000d (NS_ERROR_XPC_CANT_CONVERT_WN_TO_FUN)"  location: "JS frame :: http://192.168.1.99/tradedoubler_admin/web/scripts/pagejump.js :: jump :: line 7"  data: no]

Is any one familiar with this error? It's suppose to be a pop up box that asks if the user really want to delete this record, if he clicks yes it redirects to delete it, but if not it doesn't do anything.

Hello im having trouble with my onclick button specifically the "doall" is there a problem with my function or the button?
Console says ReferenceError: doAll is not defined but I have set the function doAll so I don't get what's wrong.

Hi,
My webpage can work normally in IE but not in Safari(e.g. when I clicked on some buttons like 'Delete' button, the page opened in Safari stays the same while it should delete the object chosen).

When I tried debugging on Safari, after clicking the 'update' button, this
message error appeared: "TypeError: Result of expression 'this.form.fireEvent' [undefined] is not a function". I believe this code makes the incompatability between the 2 browser:
Code:

    	    function DeleteClick()
        	{
        		var frmSWO = document.getElementById("form");
        		var answer = confirm("Do you really want to delete?")
				if (answer != 0)
				{
					frmSWO.action = "/domsWeb/mtd/doms/web/operation/eDepotMNR/controller/manageWorkOrder/DeleteJobOrImage.do";
        			frmSWO.method = "post";
        			this.form.fireEvent('onsubmit');
        			frmSWO.submit();
				}   		
        	}

Any suggest how should I amend the script for it to work on 2 browser concurrently?
Thanks all!

Title basically says it. I need to get the object that was just clicked, to insert into a JavaScript function. I've tried "function('this')" and similar things, but it doesn't work. I'm sure this is REALLY easy to do, but I don't know it and I have no idea what to search for.

Thanks

Hi, I am a beginner in programming however I am close to completing this task for my uni course and I know what method is needed "toLowerCase()" yet I am not sure on where it needs to be placed.

QUESTION:

Apart from any logical mistakes this thing i have created might have , my question is this.Why upon pressing the last button and calling the "scor(j)" function , no alerts pop up?Thanks in advance. I'm completely stumbled by this as i have no clue as what might be wrong.But then again , my experience is extremely limited
