How to call system property in catalog client script

[Devaceis]

how to call a system property on a Catalog client script? 

I have defined a system property where the Value is one catalog item (AB). And for this catalog in state field On Hold option is there.

Now Requirement if in future someone add other catalog item sys_id in system property so for that item also state field option on hold should be add.

Client script-

system properties-

if someone add other item sys_id in value so for that catelog item  on hold option should come in (sc_task) state field.

Thanks.

use this

function onLoad() {
	//Type appropriate comment here, and begin script below
	var ga = new GlideAjax('PropertyUtilization');
	ga.addParam('sysparm_name', 'getProperty');
	ga.getXML(myCallBack);
	function myCallBack(response) {
		var prop = response.responseXML.documentElement.getAttribute('answer');
		if (g_form.getValue('sc_task.request_item.cat_item') == prop) {
			g_form.addOption('state', '5', 'On Hold', '2');
		}
	}
}
