JSON.parse() not working in Service Portal?

[patricklatella]

Hi all, 

seeing several posts about different ways to parse a JSON in a client script to populate fields on a catalog item in Service Portal.  Not sure why my script below isn't working, anyone see what I'm missing?  thanks!

Script Include:

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

getUserInfo: function(){

var user = this.getParameter('sysparm_user');//value passed from client script
var userInfo = new GlideRecord('sys_user');//table where desired variable lives
userInfo.addQuery('sys_id',user);//field of desired variable on table
userInfo.query();

if(userInfo.next()){
var obj = {};
obj.var1 = userInfo.company;
obj.var2 = userInfo.email;
var json = new JSON();
var data = json.encode(obj);//JSON formatted string
return data;
}
},
type: 'u_Ajax_User_Info'
});

Client Script:

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

var getUser = new GlideAjax('u_Ajax_User_Info');
getUser.addParam('sysparm_name', 'getUserInfo');
getUser.addParam('sysparm_user',g_form.getValue('requested_for'));
getUser.getXML(setValues);
}

function setValues(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
answer = JSON.parse(answer); //Transform the JSON string to an object
g_form.setValue('business_unit',answer.var1);//field on form
g_form.setValue('email',answer.var2);//field on form
}

Excellent, great to know and thanks again Jim!

Here are my final scripts if you want to copy and paste them back one more time into a response I'll mark your reply as correct.

SCRIPT INCLUDE:

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

getUserInfo: function(){
var result = {};
result.company_id = "";
result.company_name = "";
result.email = "";

var user = new GlideRecord('sys_user');
if (user.get(this.getParameter("sysparm_user"))){
result.company_id = user.getValue("company");
result.company_name = user.company.getDisplayValue();

result.email = user.getValue("email");

}
return JSON.stringify(result); //return the results as a JSON formatted string
},
type: 'u_Ajax_User_Info'
});

CLIENT SCRIPT:

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

//call script include to retrieve values from the [requested_for] user record
var getUser = new GlideAjax('u_Ajax_User_Info');
getUser.addParam('sysparm_name', 'getUserInfo');
getUser.addParam('sysparm_user', newValue);
getUser.getXMLAnswer(setValues);

function setValues(response) {
result = JSON.parse(response); //Transform the JSON string to an object
g_form.setValue('business_unit', result.company_id, result.company_name);
g_form.setValue('email', result.email);
}
}
