Re: [OT] DOM & JavaScript

Interesting indeed... How about trying this... change the two lines that 
dynamically add the mouse handlers to:

row.onMouseOver = "this.className = 'hilite';";
row.onMouseOut = "this.className = 'rowNormal';";
I'm not 100% sure what the capitalization should be of the property your 
setting (i.e., row.onMouseOver vs. row.onmouseover vs. something else), 
but give that a shot... any time I've done dynamic table creation I 
don't remember ever using setAttribute() at all, I think I've written 
code like the above.

Hmm... I notice that the JSP code is referencing onMouseOver, while your 
Javascript is trying to set the attribute onmouseover... I wonder if the 
capitalization difference is an issue?  Certainly, if setAttribute() 
takes case into consideration that would do it.  You said the lines were 
identical when you looked, but could it be you glossed over the 
difference in capitalization? (I may have too).

Greetings,
Once again I call on my trusted community for insight !
I'm adding a row to a table dynamically. All is working well except for 
one thing the Mouse events.

Here is the code for adding a row to the table.
There is more code that adds the cells to the table (not shown).
...
// Only add a row when changing the last row of the table
if ("s"+(rowWithData) == selectId) {
       var row = table.insertRow(lastRowInTable);
       var className = "rowNormal";
       if (lastRowInTable % 2 == 0) {
               className = "rowAlternate";
       }
       row.className = className;
       row.setAttribute("onmouseover", "this.className = 'hilite';");
       row.setAttribute("onmouseout", "this.className = '" + className 
+ 

"'");
...
}
Here is the JSP code that creates the table row (at least one row is in 
the page), here the mouse events are working:
<tr valign="top" onMouseOver="this.className = 'hilite'" onMouseOut=
"this.className = '<c:out value='${rowClass}'/>'" class="<c:out value=
'${rowClass}'/>">

If I add an alert that dumps the innerHTML of the table after the 
row/cells are added and I compare the two rows... 
They are the same.
Why are the mouse events added dynamically not recongnized ?

BTW, using IE 6.0.2900.2180.xpsp_sp2_rtm.040803-2158
TIA,
Glenn
