Example of SCRIPT DEFER
This page has an example of <SCRIPT DEFER>. The external script that follows this paragraph takes at least ten seconds to load, much like a very long script might take. If your browser doesn't support then the entire rest of the page has to wait for the script to load.
<SCRIPT
SRC="../cgi-bin/delscript.js"
DEFER
></SCRIPT>
This is stuff after the script. If you see this text before you see the "Hi there!" alert box, then
works on your browser.
