How to access selected value of the dropdown in "processing script" in UI page

[Jahnavi6]

Hi, I need the selected dropdown value in the processing script, so that, based on the selected value, i need to redirect to some other page. Here is my HTML code:

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
	<g:ui_form>
		<select id="sel" name="sel" onchange="show(this)" style="width:400px">
			<option value="">-- Select --</option>
		</select>
		<g:ui_spacer />
		<g:dialog_button_ok ok_id="ok_button" />
		<input type="hidden" name="univValue" id="univValue" value="" />
	</g:ui_form>
</j:jelly>

Client Script: 

$j(function() {
	var ga = new GlideAjax('FetchUniversities');
	ga.addParam('sysparm_name', 'getUniversitiesList');
	ga.getXML(callbackMethod);
	

});
function show(ele) {
	alert(ele);
	document.getElementById('univValue').value =  ele.options[ele.selectedIndex].value;
}

function callbackMethod(response) {
	var answer = response.responseXML.documentElement.getAttribute('answer');
	answer = JSON.parse(answer);
	try {
		var ele = document.getElementById('sel');
		var data1 = answer.data.identityProvider.providers;
		for (var i = 0; i < data1.length; i++) {
			ele.innerHTML = ele.innerHTML +
				'<option value="' + data1[i]['idp'] + '">' + data1[i]['name'] + '</option>';
		}
	} catch (e) {
		return;
	}
}

Processing Script: 

gs.info("checbox value is : " + univValue);
if (univValue != '') {
       my_target = 'newpage.do';
} else {
       my_target = 'navpage.do';
}
response.sendRedirect(my_target);

It looks like the "onchange" function is not firing, and in the console i'm getting "actionOK" is not defined error when i click on "OK" button.

Thanks for your reply. I've got it fixed by changing the onchange function name from "show" to "somethingelse". 

Thanks!

Did you accidentally marked your own response as correct.

Would you mind marking my response as correct and helpful if I was able to help/guide you.
