I have the following code making a GET request on a URL:
$(\'#searchButton\').click(function() {
$(\'#inquiry\').load(\'/portal/?f=searchBilling&pid=
If you want to stick with Jquery's .load() method, add something unique to the URL like a JavaScript timestamp. "+new Date().getTime()". Notice I had to add an "&time=" so it does not alter your pid variable.
$('#searchButton').click(function() {
$('#inquiry').load('/portal/?f=searchBilling&pid=' + $('#query').val()+'&time='+new Date().getTime());
});
