RE: getElementById failing

[Greg Keogh]

I just noticed that the IDs don't match. In the rendered page I see this:

 

function NoteCheck()

{

  var text =
document.getElementById('ctl00_ContentPlaceHolder1_UMAuthRepeater_ctl01_conv
erseCtl_conitemCtl_textNote');

  var btn =
document.getElementById('ctl00_ContentPlaceHolder1_UMAuthRepeater_ctl01_conv
erseCtl_conitemCtl_btnConSave');

  var len = text.value.length;

  btn.disabled = (len == 0);

}

 

<td><input ...
id="ctl00_ContentPlaceHolder1_UMAuthRepeater_ctl02_converseCtl_conitemCtl_te
xtNote" onFocus="NoteCheck();" onKeyUp="NoteCheck();"
style="height:60px;width:300px;" /></td>

  

So my JavaScript logic is probably still correct, but the IDs don't match. I
also tried <%=textNote.ClientID%> style syntax instead of string.Format, but
it makes no difference. I've not seen this mismatching ID problem before,
but at least I now know why it's crashing, but don't know the underlying
cause or cure.
