Difference between 2 dates in days in catalog client script

[soumyadaggula]

Hi team , 

I am trying to get the difference of 2 dates in days , I tried below script , but its not working :

Catalog Client Scripts

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

var ga=new GlideAjax('NofDays');

ga.addParam('sysparm_name','days');

ga.addParam('sysparm_start',g_form.getValue('u_date'));

ga.addParam('sysparm_end',g_form.getValue('audit_last_test'));

ga.getXMLWait();

answer=ga.getAnswer();

g_form.setValue('audit_required_timeframe',answer);
}

Script Include :

var NofDays = Class.create();

NofDays.prototype = Object.extendsObject(AbstractAjaxProcessor, {

days:function(){

var start=this.getParameter('sysparm_start');

var end=this.getParameter('sysparm_end');

return gs.dateDiff(start,end);

},

type: 'NofDays'

});

Hi @soumyadaggula 

there is no issue found on your script but there is one suggestion, rather than use getXMLWait please try with getxml like below

ga.getXML(callback);
function callback(response) {
  var comments = response.responseXML.documentElement.getAttribute("answer");
g_form.setValue("comments", comments); //Set the "Comments" field with comments in the dialog
  }

 Please try and let me know if it helpful or not.

I get this after I update :

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

var ga=new GlideAjax('NofDays');

ga.addParam('sysparm_name','days');

ga.addParam('sysparm_start',g_form.getValue('u_date'));

ga.addParam('sysparm_end',g_form.getValue('audit_last_test'));

ga.getXML(callback);
function callback(response) {
var comments = response.responseXML.documentElement.getAttribute("answer");
g_form.setValue("audit_required_timeframe", comments); //Set the "Comments" field with comments in the dialog
}
}
