That should be more compatible than using the try..catch method and
would mean the filename you use for jQuery wouldn't matter:
<script type="text/javascript" src="jquery-latest.js#_jq_JQ"></script>
or
<script type="text/javascript" src="jquery.js#_jq_JQ"></script>
or even
<script type="text/javascript" src="elephant.js#_jq_JQ"></script>
You could even use jQuery itself to do this:
new function(){
var match;
jQuery("script").each( function() {
if(match) return false;
match = /#_jq_(.*)$/.exec(this.src);
if (match) window[match ? match[1] : '$'] = jQuery;
});
};
