Get Basic Switch To Work - GetElementById Property ?

I don't quite understand the getElementById property. Is there a way I can get it so that I click on the biography link and an alert displays?

I don't quite understand the getElementById property. Is there a way I can get it so that I click on the biography link and an alert displays?
I'm reusing a basic text sizer script and want it to focus on an element of my choice. What is fundamentally wrong with this code? The only issue is that document.getElementById(container); comes back 'not defined' in firebug, and the script doesn't make it to the alert(c) call.
The var container is passed in as 'caseDetail'. Which is a div element generated dynamically with PHP, and has the id "caseDetail". I've loaded the script dynamically inside this element itself (shame on me).
var min=8;
var max=18;
function increaseFontSize(container) {
var c = document.getElementById(container);
[Code]....
Why first or second case doesn't return the element? I debugged and I know it's id property is set in both cases, but no element return???
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "[URL]" >
<html lang="en">
<head>
</head>
<body>
<script type="text/javascript">
//// first case
//var tdiv = document.createElement("div")
//tdiv.id = "div_0"
//var element = document.getElementById("div_0")
//alert("element: " + element)
// second case
var tdiv = document.createElement("div")
tdiv.setAttribute("id", "div_0")
var element = document.getElementById("div_0")
alert("element: " + element)
</script></body></html>
check out the Social Media "more" button dropdown at:[URL]
It's supposed to grown in size, and then fade the icons up.
In IE, it grows but then does nothing.
The jQuery code:
<script type="text/javascript">
jQuery( function(){
$grown = 0;
jQuery("#more-social").click(function() {

I am using javascript to switch between a series of divs, on clicking a navigation tab the divs display property is set to 'block' and all other divs have their display property set to 'none'. That works fine, the problem I have is when I redirect to another page (e.g. a PHP script) on return to the index the divs have reset and only the default div is shown, rather than the div that was showing when the user left the page. The solution, as I see it, is two stages: Write a function to display the relevant div based on the variable passed to it, then work out how to pass this variable around various pages (post/get). I am very inexperienced with javascript and it drives me mad that the script literally does nothing rather than throwing up an error (as in PHP) but this is what I have so far in terms of a function:

Assignment:
Switch Create a HTML that uses Javascript. Create a page that tells a student the range their mark falls in if they know their letter grade. Below 50 is an "F", 50-59.9 is a D, 60 - 69.9 is a "C", 70 - 79.9 is a "B", 80 - 89.9 is an "A" and 90 - 100 is an "A+". You determine the input and output format.

If visual basic and firebug doesn't show me any error and if code doesn't work on any browser...so what should i do. I did a little boring - to read my code again to find a simple syntax errors like - writte() for exemple.
But even that does not give me anything! Is there any good recomendations how to change it all?
Look at this code:
Browser gives me out only - Please enter a valid name
I'm using a javascript file to switch out items when a thumbnail is clicked. This includes photo, title, description, price, size, quantity and add to cart button....
The original code on the html file works fine, but as soon as it is swapped by onclick, the 'add to cart' button does nothing! code...
and that adds the item to the cart just fine, but when a thumbnail is clicked on, activating the javascript file to switch out the item/elements, the 'add to cart' button no longer does anything... by the way, I am using simpleCart.js.
My switch function just goes to the default. I've double double checked the file paths of the image on the page and it's right. here's what I got:
function change2(picName,imgName)
{
switch (document[picName].src)
{

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')}
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.

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>

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);
I wanted to know if document.getElementById works while accessing form elements. I tried doing this just for testing purposes
This code doesnt work
function validateForm()
{
var val = document.getElementById("id_login").getAttribute("value");
alert(val);
return false;
[Code]...
Why doesnt document.getElementByid work with form objects.it works with all non form HTML objects..
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'm trying to move a div with the animate(); Method but doesn't work with the top css property
this is the method that I use
$('.btnControls').click(function(){
$(".itemContainer").animate({top:"200px"});
});
Which is the reason for doesn't work.?
I'm writing a script that dynamically generates a menu table. Each TD has an onclick property which serves as a link. Everything works properly in other browsers since setAttribute onclick works. However, this function does not work in IE, and you're supposed to do this instead:
elementName.onClick = "blah";
Here's my code that works in all browsers but IE:
Code:
var truePath = "document.location.href=" + "'" + "/" + urls[i] + "'";
cell.setAttribute("onclick",truePath);
cell.onclick = truePath;
For IE, if I set the cell.onclick value to truePath, nothing happens when I click on the menu. However, it works fine in Firefox and Opera because of the setAttribute function. How I could get this to work in IE? My script is complete besides this part... I hate IE. Why can't they follow the rules?
If I switch the w3schools' file with the same local file, it will not work with firefox.Does anybody know why the local file is not displayed correctly?

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.
Why doesnt the following code work in IE. There is an error on the same row as fillText. It says object doesnt support this property or method.

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.

Ive got a really simple problem but I can't figure it out. I've got a
form named bob with one text box name bobtext with a default value of
"http://". When I add onload="document.bob.bobtext.focus()" it focuses
on the text box, but at the beginning. Is it possible to focus on the
text box, but at the end of "http://"? This seems like something easy
so I'm probably making some stupid mistake.
Suppose I have a page, call in parent.html . Inside, there is an iframe,
call it child.html . I want it so that in response to a keyboard event
in either parent or child, child.html will respond in a particular way.
Do I need to use a different set of code for each html page, or can I
reuse the same code?
If the code is different, what are the fundamental differences in code?
How do I make one frame respond to events in a different frame as a
general rule?
I know there is a million of them but here's a little calculator script I made just for kicks. Feedback is always appreciated, good or bad.
I think I did a pretty good job of mirroring the windows calculator functionality.
Basic keys are mapped (optionally) to the keyboard.

I'm using XHR to make some REST requests. Right now I need to handle HTTP 401 responses.When a resource is requested such as a Javascript file or CSS file the browser will popup a prompt for username and password, which is normal behaviour.When I make an XHR request for POST,GET or PUT I get an XHR response which includes a status of 401 and no popup from the browser, this is also normal.The problem is when I make a DELETE request, I get the expected XHR response AND also the browser still pops up the username and password prompt.
