GlideAjax not working in client script

[Ahmad6]

Hi guys,

I've tried to follow the guide at https://community.servicenow.com/community?id=community_article&sys_id=9f7ce2e1dbd0dbc01dcaf3231f96196e to create a client script which uses script include but the script is not accessing the script include (or i'm not reading the data correctly). I have used this process in other Client scripts in slightly different manners and they work fine so i'm not sure what's happening, if I can get another set of eyes that would be greatly appreciated.

The table inherits the incident table, and uses a matrix of category/subcategory to determine the priority/SLA duration.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }

	var ga = new GlideAjax('AL_SCRIPT');
	ga.addParam('sysparm_name','getPriority');
	ga.addParam('sysparm_category', g_form.getValue('category'));
	ga.addParam('sysparm_subcategory', g_form.getValue('subcategory'));
	ga.getXML(parseAjax);
	
}

function parseAjax(response) {
	var answer = response.responseXML.documentElement.getAttribute("answer");
	g_form.addInfoMessage('priority: ' + answer);
	if(answer){		
		g_form.setValue('priority',answer);
	}
	
}

script include below:

var AL_SCRIPT = Class.create();
AL_SCRIPT.prototype = Object.extendsObject(AbstractAjaxProcessor, {
	
	getPriority:  function () {
	gs.addInfoMessage("finding priority");
	var category = this.getParameter('sysparm_category');
	var subcategory = this.getParameter('sysparm_subcategory');
	
	var gr = new GlideRecord('u_ncr_matrix');
	gr.addQuery('u_category', category);
	gr.addQuery('u_subcategory', category);
	gr.query();
	if(gr.next()){
		return gr.u_priority;
	} else return false;
},


type: 'AL_SCRIPT'
});

Try the following code in background and let me know the result,

var gr = new GlideRecord('u_ncr_matrix');

gr.addQuery('u_category', category);

gr.addQuery('u_subcategory', category);

gr.query();

if(gr.next())

{

gs.print(gr.u_priority);

}

else

gs.print( "false");

also why we have category twice ....in the glide record of the u_nsc_matrix

Hi Rahul,

The issue was with the client callable box not ticked, I've picked up on the category thing and corrected it in my code already though.

Thanks for your help.
