I'm trying to make a very simple page where you click on a <td> in order to change the color. However, I find that if I handle the "ondblclick", the space I have in the <td> gets automatically selected. Since I've specified the ondblclick event handler, I'd assume that this would overload the "double click selects a word" in the <td>.

Reproducible: Always

Steps to Reproduce:
I'll attach a html file demonstrating this problem. To reproduce, simply double click on the table element.
Actual Results:  
the space in the <td> gets selected along with the <td> changing color.

Expected Results:  
the <td> should just change color.

I see the same thing you see.  I'm using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20051209 Firefox/1.6a1.  I also see the same behavior using IE7.

Setting up an event listener never automatically cancels the default action, as far as I know.  Returning false or calling event.preventDefault() from the event listener, however, usually does cancel the default action.  I think it's a bug that returning false doesn't prevent the default action (word selection) for double clicking.  Even calling event.stopPropagation() from a capturing dblclick handler doesn't prevent word selection.

As a workaround, you can make your table cell be truly empty, and make the cell appear by putting style="empty-cells:show;" on the table.  That doesn't seem to work in IE7, though.

Summary: using "ondblclick" event on a <td> in a table shouldn't cause text selection → ondblclick event should be able to cancel word selection (e.g. using preventDefault)

Note that you'll only see the undesired behavior in IE if your cursor is over the &nbsp; when you double-click.
