GlideAjax

[desaiakash0]

I've created a GlideAjax script to automatically populate the location field whenever a caller is selected. However, the location is displayed correctly initially but then disappears automatically. Additionally, attempts to display the location through an alert message result in 'null' being shown.I have attached the screenshots of Script inlcude code, client scirpt code and output window.

I'm seeking assistance to resolve this issue.

Do you have any other client scripts or UI policies affecting this field/variable?

[Zach Koch]

In your Script Include, it needs to look like this as you have to use this.getParameter('<your_parameter>') to get your param

getCallerLocation: function() {
    var userID = this.getParameter('sysparm_caller_id');
    var userRecord = new GlideRecord('sys_user');
    userRecord.addQuery('caller_id', userID) //or whatever field you are using this data to search on if it's not caller_id
    userRecord.query()
    if (userRecord.next()) {
        return userRecord.location.name;
    } else {
        return 'Record not found';
    }
}

Here is a great link that breaks it down
