JSon Callback

[welshgaz]

Hi Guys,

I'm slighty missing something here on the JSon callback support...

I've written this segment of code...

<script type="text/javascript">
	function processresults(obj) {
		alert(obj);
	}
</script>
<script type="text/javascript" src="http://www.applicationaddress.com/app/Data?data=12&output=json&callback=processresults" />

This data servlet will then return a JSon object such as...

{"items":[{"url":"http://www.address1.com","page":0,"pagetitle":"Address 1"},{"url":"http://www.address2.com","page":3,"pagetitle":" Address 2"}]}

but the processresults() function is never being called ie. the alert is never raised.

What am I missing here, do I need to add something specific into the servlet code ?

Thanks

sorted... The issue was the JSon returned object wasn't wrapped in the javascript function code i.e. the object should have been

processresults({"items":[{"url":"http://www.address1.com","page":0,"pagetitle":"Address 1"},{"url":"http://www.address2.com","page":3,"pagetitle":" Address 2"}]})
