ID Property Set But GetElementById Not Working
Apr 12, 2011
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>

"<body>
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?

There is a main page. in that mainpage there is a iframe and in that iframe (id = DocFrame) there is a textbox (id="fileuploadedcnt") which i am trying to access. there is no error. ofcourse i have given name and id to the textbox. Below is the code

Code:
I've got the content div to auto stretch to fill the content size, but the blocks at the side don't follow thru. I'm using some Javascript code I found here to fix that, and it does in IE6 and Opear6, but not in Firebird. For some reason it won't read the actual height I've already specified (in any browser), but specifically in Firebird it won't adjust the size.

Why does'nt the arrayvalue work?
I'm sure its foo. Is it some string conversionproblem. I've tried a lot but nothing works.
Code:
function handleResponse() {
if(http.readyState == 4){
var response = http.responseText;
var update = new Array();
if(response.indexOf('|' != -1)) {
update = response.split('|');
document.getElementById(update[0]).innerHTML = update[1]; //Dont work.
//document.getElementById('foo').innerHTML = update[1]; //Works!
}
}
}

I am using a text link to submit a form with the following funciton:
<a href="#" onmousedown="javascript: getElementById(form1).submit();>CLICK HERE</a>
It works beautifully in IE but not at all in Firefox. I use the same piece of code to submit a form using an image and it works with the image.
Any one have any idea how to fix this in Firefox/Mozilla?

First a little background. I have a client (in-house) who insists that our training pages (launched from within iframes on a parent page) be able to load .wmv files with variables for the width and height parameters so we don't have to recode when videos are switched. Flash videos are not an option.
I've searched the net and have received several suggestions and even code snippets from several sources but the only one that comes close to working is this one:

The following code displays the name for all three elements in IE, but fails
for the1st and 3rd in Firefox. What could be going on? I tried SPAN instead of DIV doesn;t work either. (What I finally want is to set style.invisibility for the text in that DIV) Code:

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 am trying to show and hide different div objects on a webpage all with different ID's as you can see. Only the first object will work "('killstreakwin')", or any that is put first, none of the others work after that. It's not the HTML side, it's definatly the javascript function. I've tried to use a loop but I don't know how to implement it into something like this.

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 have two objects that I am trying to merge together using $.extend().
As long as I only use objects 1 level deep everything merges correctly.
objOne = {
face: "book",
captain: "crunch"

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 am trying to alter css using javascript as well as use the innerHTML
function. I have pasted below 3 forms that access getElementById in
slightly different ways (I wanted to rule out that it was the method.)
All 3 work fine on IE but only work momentarily on Firefox. For
example, one form has text that changes from red to black when the user
clicks the button. In IE it changes. In Firefox it changes for a
split second then goes back to black. Code:

I have this problem and when I came looking for help, I checked out the other thread like this but I couldn't get it to work. Here is the function -
PHP Code:
function newForm(focus, field)
{
if ( focus == 'no' )
{
if ( document.getElementById(field).innerText == '' )
{
document.getElementById(field).innerText = '____________'
}
}
if ( focus == 'yes' )
{
if ( document.getElementById(field).innerText == '____________' )
{
document.getElementById(field).innerText = ''
}
}
}
and here is the form -
PHP Code:
<b>Field 1:</b> <input type='text' name='field1' class='textbox' value='____________' onFocus="newForm('yes', 'field1')" onFocusOut="newForm('no', 'field1')" /><br /><br />
<b>Field 2:</b> <input type='text' name='field2' class='textbox' value='____________' onFocus="document.form.field2.innerText=''" onFocusOut="document.form.field2.innerText='____________'" /><br /><br />
field1 uses the function but field2 uses just onFocus and onFocusOut but as you can see, it won't work.

Works fine in FF, Safari . . . but not with IE. The error is "Object doesn't support this property or method".I have narrowed it down to this line (and a few like it)name = escape(document.getElementById('name').value);The escape() is not the issue, same with or without.I am trying to capture the text value from the field with id='name'. I have found discussions about this problem with IE, but not a solution. This must be easy, just trying to get a cross browser solution to load a JS variable with an <input> value.
