If there is no need for the additional function you could always just
write it like so:
$(document).ready(function() {
$('a.taglink').click(function() {
var t = $(#tags);
if(!(t.val()) {
t.val(this.txt);
return;
}
var ss = t.val().split(this.text);
if(ss.length <= 1) {
var wa = (t.attr('value')+',' +this.text).split(",");
wa.sort();
t.val(wa.join());
}
});
But then again if you're using the tagSelect function for another
purpose then stick with Christof's code :-)
