Callback function used for g_form.getReference is not working in portal

vanessaheux · ‎09-24-2019

Hello,

I have a country variable in a request item which is automatically filled thanks to the country of the location (location which is another variable in the same request item).
When location is filled, country is automatically filled.
This works thanks to a catalog client script. It only works on the platform but not in the portal.
I know that g_form.getReference can’t be used in catalog client script and so we need to create a callback function.
I created it but I still have the problem : ok on the platform but not in the portal.
Here is the catalog script I wrote:

function onChange(control, oldValue, newValue, isLoading) {
var caller = g_form.getReference('user_location', doAlert); // doAlert is our callback function
}
function doAlert(caller) { //reference is passed into callback as first arguments
g_form.setValue('user_country',caller.country);
}

Do you have any idea why it is not working in the portal ?
Thanks
Vanessa Heux

if above solution not working , replace the code with script include + glide ajax .

try now with below sample code.

Sample Code:

Script Include:

var getCountry = Class.create();
getCountry.prototype = Object.extendsObject(AbstractAjaxProcessor, {

	getCont : function(){

		var cnt = this.getParameter('sysparm_user_name');

		var gr = new GlideRecord('cmn_location');
		gr.get(cnt);
		var cmn = new GlideRecord('core_country');
		cmn.addQuery('name',gr.country.getDisplayValue());
		cmn.query();
		if(cmn.next()){
			return cmn.sys_id;
		}},

	type: 'getCountry'
});

Catalog client script:

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

	//Type appropriate comment here, and begin script below
	var caller = g_form.getValue('user_location'); // make sure about the variable name
	var ga = new GlideAjax('getCountry');
	ga.addParam('sysparm_name', 'getCont');
	ga.addParam('sysparm_user_name',caller);
	ga.getXML(HelloWorldParse);

	function HelloWorldParse(response) {
		var answer = response.responseXML.documentElement.getAttribute("answer");

		g_form.setValue('user_country',answer); // make sure about the variable name
	}

}

Note: Validate the variable name in above client script.
