document.getElementById(cis) has no properties

DD Tab Menu II
http://dynamicdrive.com/dynamicindex1/ddtabmenu2.htm

I am getting an error running on the script listed above. The error I'm getting is saying:

document.getElementById(cis) has no properties

Here is the code related to this error. Italicized is the only part of this code that refers to 'cis'. I did place the second portion of the code as well, but there is also no mention of 'cis' there either. I thought at first this had to do with a tag needing to have an id of cis but I really have no idea why this error keeps popping up. Any help would be much appreciated.

Thanks guys.

No mention of "cis" there. It's "cid."

In reply to the...

No mention of "cis" there. It's "cid."

Yes, I'm a moron...I meant the error is:

document.getElementById(cid) has no properties

Anywhere I mentioned cis replace with cid.

Ah, OK. What does the tag look like where you use expandcontent()?

In the javascript...

function expandcontent(cid, aobject){
if (disabletablinks==1)
aobject.onclick=new Function("return false")
if (document.getElementById && turntosingle==0){
highlighttab(aobject)
if (previoustab!="")
document.getElementById(previoustab).style.display="none"
document.getElementById(cid).style.display="block"
previoustab=cid
}
}

In the HTML...

<a href="#" onMouseover="expandcontent('LINK1', this)">Link1</a> | <a href="#" onMouseover="expandcontent('LINK2', this)">Link2</a> | <a href="#" onMouseover="expandcontent('LINK3', this)">Link3</a> | <a href="http://url/" onMouseover="expandcontent('LINK4', this)">Link4</a> | <a href="" onMouseover="expandcontent('LINK5', this)">Link5</a>
</div>
<div id="Navcontainer">
<div id="LINK1" class="tabcontent">
<a href="#" target="_self" id="cid">SubLink1</a> | <a href="#" target="_self" >SubLink2</a> | <a href="#" target="_self" >SubLink3</a>
</div>
<div id="LINK2" class="tabcontent">
<a href="#" target="_self" >SubLink4</a> | <a href="#" target="_self" >SubLink5</a> | <a href="#" target="_self" >SubLink6</a>
</div>
<div id="LINK3" class="tabcontent">
<a href="#" target="_self" >SubLink7</a> | <a href="#" target="_self" >SubLink8</a> | <a href="#" target="_self" >SubLink9</a>
</div>
<div id="LINK4" class="tabcontent">
<a href="#" target="_self" >SubLink10</a> | <a href="#" target="_self" >SubLink11</a> | <a href="#" target="_self" >SubLink12</a>
</div>
<div id="LINK5" class="tabcontent">
<a href="#" target="_self" >SubLink13</a> | <a href="#" target="_self" >SubLink14</a> | <a href="#" target="_self" >SubLink15</a>

Is that last div ever closed?

Yes, the last div is closed. The thing I find hard to figure out is what 'cid' is for. I don't show it listed as any id anywhere. If I knew what part of the code the cid was for I would at least know where to look for the error.

This bold line is the specific line that is giving the error in the browser.

function expandcontent(cid, aobject){
if (disabletablinks==1)
aobject.onclick=new Function("return false")
if (document.getElementById && turntosingle==0){
highlighttab(aobject)
if (previoustab!="")
document.getElementById(previoustab).style.display="none"
document.getElementById(cid).style.display="block"
previoustab=cid
}
}

The part of the code you have there is the only part that has access to cid, for a start, as it's a function argument. The place to look for the error is in your HTML, as you've pasted it above. The first argument you're passing to expandcontent() (at some point) isn't valid. Do you have a line/character reference, or could you provide a link to the page in question?

That is a link to the page that has the error. I did figure it had to do with the HTML in reference to an id that would have been cid, but since that is not the problem, that's why I'm having the issue.

Aha.
The problematic ID is here:

Code:

//Set tab to intially be selected when page loads: //[which tab (1=first tab), ID of tab content to display]: var initialtab=[1, "sc1"]

Element with ID "sc1" obviously doesn't exist. If you don't want a tab to open initially, simply find and remove the following line:

Code:

expandcontent(initialtab[1], tabobjlinks[initialtab[0]-1])

It's in do_onload().

Awesome. It works, thank you very much Twey.

And just to clarify that I understand what you're saying. B/c sc1 hasn't been selected you basically cannot have it initially selected...that being because it doesn't exist until it is selected?
11-19-2005, 07:50 PM
Twey

No... you can't have it initially selected, quite simply, because there is no element with the ID "sc1."

Okay, yes, I understand now. I had been looking at a bunch of other scripts trying to figure out this issue and saw others using sc1 and forgot it wasn't in the script I was using.

Thank you again though, I really appreciate it.
