I started a thread here document.getElementById not working but it looks as though even the suggestions made were valid I still have a problem.

I have a couple of checkboxes. When i view the page source here there are. document.getElementById('chk1') is the only one that is not null. How could that be?

<input id="chk0" value="JobStages###StageCode~JobCode###DRAW~1005" onclick="addRemoveRow(this.value,this.checked)" style="border-width:0px;padding:1px;margin:0px;height:14px;"  type="checkbox" />

<input id="chk1" value="JobStages###StageCode~JobCode###FEAS~1005" onclick="addRemoveRow(this.value,this.checked)" style="border-width:0px;padding:1px;margin:0px;height:14px;"  type="checkbox" />

<input id="chk2" value="JobStages###StageCode~JobCode###N/C~1005" onclick="addRemoveRow(this.value,this.checked)" style="border-width:0px;padding:1px;margin:0px;height:14px;"  type="checkbox" />

EDIT: Pretty much the complete code

You are probably executing the javascript before the DOM nodes are available.

this will not work

<script type="text/javascript">
  // trying to retrieve #chk1 before it exists in the DOM!
  document.getElementById('chk1');
</script>

<input id="chk1">

Whereas either of these will

<input id="chk1">

<script type="text/javascript">
  // #chk1 exists in DOM, this works
  document.getElementById('chk1');
</script>

or

<script type="text/javascript">
  // Force execution to wait until window is done i.e, DOM is ready
  window.onload = function()
  {
    document.getElementById('chk1');
  }
</script>

<input id="chk1">
EDIT

I copied your entire chunk of HTML from above, added this to the end of it

<script type="text/javascript">
alert([ 
    document.getElementById('chk0')
  , document.getElementById('chk1')
]);
</script>

and opened it in IE7. The alert produced [object],[object] which means it worked and found both nodes. Not sure what to tell you.

innerHTML JavaScript Property: Learn to Use JS innerHTML, know that there is an element with the specified id. You need to use "document.getElementById" function - notice the last "d" is lowercase

I know this post is old, but I found it while looking for help on a similar issue: .getElementById was not working for me with input type=text. Works fine for select controls, and works fine for me for input type=text on other pages in my system, but I was pulling out my hair for hours trying to get it to work on this one stupid page... Called from window_onload, not a dom issue, blah blah blah.

I still don't know why it's not working, but I was able to successfully use .getElementsByName as a replacement. May not be ideal but it should definitely get you moving forward again. Hope this helps.

TypeError: document.getelementbyid() is null, appropriately defined, or there are some mistakes in JavaScript code. Im new at this. Im working with the following and trying to use $(document).ready() but it wont work. Heres what I am adapting and I can get it to work fine: window.onload = function() { var headline = document.getElementById(headline), subhead = document.getElementById(subhead); TweenMax.stagger

I agree with the other answer, you are probably trying to access the dom before its loaded. Try this

window.onload = function(){alert(document.getElementById('chk1'));}

See how that works for ya

document.getElementById not working / Display, code is executed before the page is fully loaded, so its not able to find the element. My previous code was working i firefox and IE As you said, i made changes in function, but still its not working. What is the problem for simple enable and disable?

just a hunch, but maybe ie8 doesnt like it when the input dont have a name (especially since they are checkboxes)

Are you using the .checked property of the checkbox to see if it is checked or not? Take a look at this example. It explains how you may evaluate a checkbox's check state.

  • Can you post your complete code?
  • Not possible I don't think. As I stated in the example I can access the middle checkbox (chk1) so if what you were saying was true I would not be able to access any of them. This is a v strange problem to me
  • I know that Peter I tried that myself. On the face of it everything looks ok. I guess i should have phrased my question something along the lines of , what can cause a document.getElementById to fail , e.g. invalid characters in the id etc
  • ...and, since getElementsByName returns and array you will need to reference an index to get and set values, such as: var txt = document.getElementsByName(textbox_name)[0].value;
  • +1 for sharing your solution :)
  • Same issue here, no problem with the onload, doesn't even work in Googledev tools 5 minutes after the page loaded.. Switched to getElementsByName and works like a charm! Thanks
  • I'm trying to access the element in a js function which is a handler to a button click event. I'm only pressing this once the page is fully loaded. Nothing else is called before button onclick event
  • It doesn't matter that it's deprecated if the browser he's testing still uses it. IE6 for example could have trouble.
  • Name is only deprecated for the elements a, applet, form, frame, iframe, img, and map. Not deprecated for use with the input tag.
  • @Jason what are you talking about? name isn't deprecated for form elements.
