Page_Validators array returns the same metadata that we receive in custom validation function. It means that you can receive the associated control identifier something like this Page_Validators[0].controltovalidate
.
<script>
$(function () {
// process all validators and their controls
$.each(Page_Validators,function (i,v){
if(v.controltovalidate) {
$("#"+v.controltovalidate);
}
});
});
</script>
