GetElementById Not Working - How To Make It Work

Dec 27, 2010

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.

Onmouseout Not Working - How To Make It Work

Jun 9, 2009

I have a webpage with addition questions for numeracy training. I am storing the sums in a table(id="sums"), with an empty textbox(id=ans1) for the user to type the answer. After the user types an answer and moves onto the next Q, I want to activate a popup dispaying if the answer is correct or not. I am tackling this with onmouseout. The script checks the answer, then displays a confirm message if correct or and alert message if wrong. The onmouseout is not working

Code:

input type="text" name="ans1" size="1" maxlength="2" id="ans1" onmouseout="checkAns1();"

Code:

function checkAns1(){
if(document.sums.ans1.value==(document.sums.Q1R1.value + document.sums.Q1R2.value)){
var confirm("correct");

Stickies App Not Working - How To Make It Work

Mar 19, 2009

I must have a syntax error, because this function crashes the entire script (even the other functions).

function newNote()
{
allNotes = document.getElementById('notes-stickies-app').innerHTML;
secondadder = 1;

[code]...

EDIT: to get to the stickies part, click the apple menu, and click stickies. you'll see how the stickies wont drag because this script that adds new stickies has a problem.

Loop Function Not Working - How To Make It Work

Jun 8, 2009

I have a pretty simple function set up to pull XML data into my page, but there's a couple things wrong with it. I'm REALLY new to J Script and really trying my best to learn, but for some reason I'm not yet adept at googling the right results :rolleyes:At the very bottom you can see the data from the first XML entry, so it seems the function itself is working fine, but it's not looping coorectly to access all the data.Also, I want to pull it into the "shows" div of the page, but can't figure out how to put it there (seriously, I am very new with JS). The code below is not working, but the live site has it added to the body, which does show the one entry.Here's the XML function, the XML data and the HTML markup:

Shows function -

function loaddates()
{
var xmlData = document.getElementById("tourdates");
var newDates = xmlData.getElementsByTagName("dates");

Logical Operator Not Working - How To Make It Work

Jul 14, 2010

What kind of logical error am I making? I want the alert(); to execute if both of the variables (cjob and czip) are blank, but the only way I can get it to work is if I replace && with ||.

if(trim(cjob.value) && trim(czip.value) == '')
{
alert('Hello');

Does Document.getElementById Work Without A Parameter?

Jun 15, 2011

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')}

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.

Firefox & GetElementById('main_txt') Doesn't Work

Jul 23, 2005

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);

Document.getElementById('div_name').style.display Should Work?

Dec 10, 2010

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?

Firebird And GetElementById Not Working

Jun 17, 2003

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.

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!
}
}
