I think that selectedIndex will default to 0 if the selected attribute
is not set explicitly. The only workaround/hack I can think of is to
look at the innerHTML to see if it was set explicitly. Maybe something
like this:
jQuery("select").each(function(){
var thisSel = jQuery(this);
var oldVal = thisSel.val();
var setzero =
this.innerHTML.toLowerCase().indexOf('selected')
== -1 &&
this.selectedIndex==0;
thisSel.html(jQuery("option", this).sort(function(a, b) {
return a.text == b.text ? 0 : a.text < b.text ? -1 : 1
}));
if (setzero){
thisSel.attr("selectedIndex",0);
}else{
thisSel.val(oldVal);
}
});
Won't work on IE since it rewrites all of your option elements.
