Example

This example shows how to determine the origin of the onmousedown event when event bubbling is used.

Sample Code
<BODY onmousedown="alert(event.srcElement.tagName)">
<TABLE BORDER=1>
  <TH>Click the items below with your mouse.</TH>
  <TR><TD><BUTTON>Click Me</BUTTON></TD></TR>
  <TR><TD><INPUT TYPE=text VALUE="Click Me"></TD></TR>
  <TR><TD><SPAN>Click Me</SPAN></TD></TR>
</TABLE>

   the onmousedown event has fired.
</BODY>
