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 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.

Should I use both name and id
<div name="abc" id="abc"> for using getElementById in NS?
I've been trying to follow the example from the sitepoint book on DHTML to change the href property of a link, but it doesn't work no matter what I try. Here's the code in the HTML file: Code:
View 1 Replies View RelatedI 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.
View 7 Replies View RelatedMy document had the following nested DIV structure, with a possible

How do I refer to multiple elements with IDs such as question1,

document.getElementById('question').innerHTML

I came across a third party script I want to learn how to configure as
well as learn more dhtml in the doing. I'm not much of a JS guy yet
but I'm working on it.
This script works fine in IE6 but is a dead fish in FireFox. There is
no support offered on the site where it came from.....
Is there any wildcard, like *, for addressing all the element ID's on the
page at once, like if you want to hide all layers at once. For example:
document.getElementById('*').style.visibility = 'hidden'
I know the above doesn't work but you get what I'm driving at right? Is
there anything like that for that method or in javascript in general?

I'm trying to access a form value by using getElementByID and in NS i
end up with a null reference.
The following HTML is the form component that gives me headache:
<form name='task' ...>
....
<select name='prioritySelect' class='selectwidth'>
<option value=''>Choose one</option>
<option value=Ƈ'>Critical</option>
<option value=ƈ'>High</option>
<option value=Ɖ'>Medium</option>
<option value=Ɗ'>Low</option>
</select>
....
</form>
And the related javascript code:
if(document.getElementById("prioritySelect").disabled == false)
{ ... }
When digging into this I can get the desired information by using
document.task.prioritySelect, but that should not be necessary, right?
I hope that anyone knows how to deal with this problem..

Why? And how do I correct?
Is it just me, or do variables not work in getElementById? For example:
document.getElementById("div"+divnumber)...

View 2 Replies View RelatedI've built a table on the fly within a js function. In another function I'm trying to get the value of a cell in a particular row on that table. I've retrieved the cell object but cannot get it's value :
var claimDate = parent.expenseDisplay.document.getElementById("row"+lineNo+"Date");
now I thought that the following would give the the data
var cdate = getObject(claimDate).value;
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.

getElementById Bugs
There are two getElementById bugs up for discussion:
1. getElementById is case-insensitive but it should be case-sensitive.
2. getElementById searches NAME attributes as well as ID attributes but it should not.
My tests show that IE 6 and down have both bugs, Opera 9.02 has bug #2, Opera 7.54 has neither bug, and FireFox 1.5.0.7 has neither bug.
My proposed solution relies on something I noticed while testing in IE: "document.all" is case-sensitive altho it too searches NAME as well as ID attributes.
I would really appreciate if some different people could help me verify these findings in different browsers and on different platforms.
There has been another proposed solution - but I really don't like removing the ID attribute.
I want to set up a large section page with perhaps as many as several hundred items showing thumbnail image, link to item page, and info in text about the item. The sections will be dynamically generated on the server side from a database of items. I need to be able to use JS to grab the content of selected DIVs into an array for disp[lay in a right column. So I am thinking to set up a JavaScript that can read an array of DIVs that have been selected by the user checking a checkbox within each individual one they want added to their collection. This MUST be done in JavaScript, not server side.
I might assign each a sequentially IDed DIV like <div id="itm1"> and <div id="itm2"> and so forth. Can I use wildcards both for CSS styling of an unknown number of DIVs and for reading reviewing an unknown number of them using getElementById?
I don't think getElementByTag will work because there are other DIVs I do not want, and GetElementByName won't work because Name is not a valid attribute for a DIV. Or should I assign each of the IDs a class, and use getElementsByClassName? What's the most logical appraoch?
here is the code:
Code:
<body onload="loadStream()">
<script type="text/javascript">
