Nested Arrays Won't Work In GetElementById
Aug 19, 2010
I found an example code browsing on the internet that I have used to put partly transparent pictures on top of a background image (a map with several areas), The partly transparent pictures is used to change the color of an area when that area of the map is clicked (I have put a transparent image map on top.) In my css style section the display for the pictures is set to display:none I now want to extend the script to make it possible to click on an other part of the background map and change the color of that area without changing the color of the first area. My idea was to use nested arrays for this, and thus reuse the function changeImage. To test this I tried to add a new array but for some reason it doesn't work.

I can't figure out why this doesn't work:
---------------------------------------------
greeting = new Array();
greeting[0][0] = "hey";
greeting[0][1] = "bye";
trace(greeting[0][0] + greeting[0][1]);
---------------------------------------------
Shouldn't this automatically create a multidimensional array? Can someone
help me?

I cannot get the 2 getElementById functions to work and I am a beginner so I am sure it is something simple but I have not been able to fix it. I need to click on the text to change the font.

I'm a perplexed nube, and I can't understand how document.getElementById evaluates to true when no parameter is passed to getElementById. This code alerts 'foo' if (document.getElementById) {alert('foo')} else {alert('bar')}
Just to double check, this code alerts 'bar'
if (!document.getElementById) {alert('foo')} else {alert('bar')}

This seems like a total beginner thing, but I don't know why it isn't working. I'm working from examples from a sitepoint pdf. Here's my html:
Code:
<body>
<h1 id="stupid">sdfasd</h1>
<p>sdjfa</p>
[code]....
When I run an if statement, I'll get an alert letting me know that the value of target is null, but why is it null? It should contain a reference to the h1 node.

I've got here a sample of my function which is supposed to fade a
certain piece of text to another colour. This line is then located in a
for loop and it works pretty well in IE 6. However, in Firefox, and thus
I assume it will be the same in Netscape and Mozilla, it gives a problem
with the: getElementById('main_txt'). Due to that in setTimeout("",) it
requires the "" signes and thus I can not use the same ones in the
getElement part. IE has no problem with using '' in there, Firefox,
however, does. Can anyone think of how to get around this and make
firefox do this?
window.setTimeout("document.getElementById('main_txt').style.color =
'rgb("+red+","+green+","+blue+")'",delay*step);

The Javascript
Code:
document.getElementById('all_days_div').style.display = 'none';
The HTML section containing the div the Javascript should be hiding
Code:
<div id="all_days_div" style="display:block;">
<p align="right" >
Show All Days
</p>
</div>
When the JavaScript code is called, instead of hiding the div, I get the following error:"Cannot read property style of null" Do you see anything wrong with what I've written, or is my problem elsewhere?

I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. :confused:
The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing.
function testWrapper()
{
function frequencyWrapperOne()
{

I want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.
In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.

I keep getting an error stating "getElementById("ballElement") is null, but I have a div with that exact id. I have looked at the JS script before that line, but found no errors there either. Please take a minute to see if you find something.

I'm
trying to make a web page with tabs which you can navigate between
without the page reloading. I have one set of tabs working great, but
when I add nested tabs there is a problem with the 'visibility' not
being inherited and some parts stay visible in the sub-tabs. Sorry if
this is unclear.
Here's how I have it layed out: I have a <span> for each content
section of a tab. Then I have do the same thing for the content of each
inner tab. When a tab is pressed some javascript code goes through and
makes all content sections hidden and the content section for the tab
that was pressed visible. If I select a tab and then select an inner
tab it looks like is should, but when I try and select a different tab
for the outer tabs the content for the inner section doesn't go away.
I've found that this is because visibility is not inherited. My
question is if anyone has a solution for this problem. I'm sure there
is somebody that knows of some javascript trickery to do this.

I'm a greenhorn in SVG and javascripting but I'm learning by doing.
So, here my current problem question :
I have a svg document embedded in another svg document. I whant,
through functions in an external javascript file, manipulate objects
in either the child svg document or the parent document.
How do I get access to elements of the other document ?
Example : I have a document "A" containing X/Y - Axis and included
another svg document "B" with the graphs.
I whant now, as soon as the mouse cursor is over a graph in document
"B" the belonging lable which is located in the parent svg document
"A" to change color or size.
Or I whant the graph in "B" to start blinking as soon as the mouse is
over the lable in "A".
I don't know how cross document borders.
Can anyone give me a short exapmle to get me going?

Our application has a main window (call it window_1) which opens a
popup to display application data (call it window_2). This popup in
turn opens a 3rd popup with additional application data (call it
window_3). This 3rd popup window should reload window_1 when it loads
without reloading window_2.

I can alert (foo) to see the function source
Is there an alert (<something>) that will show me only the source of
function bar inside function foo ?

I really can't figure out why it's not working in IE. The only problem I can think of would be using nested loops. Here's the part of the code that isn't working. It's not generating an error, it's just not returning anything. I know you guys hate when I post entire code, so I trimmed it down as much as I can. It's referring to an already stated xml document with xmlDoc. And it's goal is to return a table of rows that meet certain criteria. If you can see any syntax errors that explorer would not like, that's really what I'm asking for.
