Explain each step that needs to be done on script include side to use it for GlideAjax?

Hi @sandeepgujj ,

Let me explain you with one real time example.

Suppose we got a requirement from client stating While creating incident if user select VIP caller, then set the priority critical.

To achieve this you need to do following.

1. Create one client script to make Ajax call.
2. You need to write script include to write your logic. Make sure script include is client callabl.

Client script code:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    //Type appropriate comment here, and begin script below
    var ga = new GlideAjax('UserUtils');
    ga.addParam('sysparm_name', 'checkVipUser');
    ga.addParam('sysparm_caller_sys_id', newValue);
    ga.getXML(ValidateVipUser);
    function ValidateVipUser(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        
        if (answer=='true') {
            g_form.setValue('priority', 1);
            g_form.setValue('urgency', 1);
            g_form.setValue('impact', 1);
        } else {
            g_form.clearValue('priority');
            g_form.clearValue('urgency');
            g_form.clearValue('impact');
        }
    }
}

Explanation:

Server Side code:

var UserUtils = Class.create();
UserUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    checkVipUser: function() {
        var caller = this.getParameter('sysparm_caller_sys_id');
        var gr = new GlideRecord('sys_user');
        gr.get(caller);
        return gr.vip;
    },
    type: 'UserUtils'
});
