Hello @Kongaleti Navee ,

Yes you can debug both scripts by adding the logs inside, please refer the below scripts with added logs.
Script Include:

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

    returnDetails: function () {
        var sys_id = this.getParameter('sysparam_caller_id');
        gs.log("SI_ReturnUserDetails - sysparam_caller_id: " + sys_id);

        var gr = new GlideRecord('sys_user');
        gr.get(sys_id);

        var usrobj = {
            email: gr.email.toString(),
            firstName: gr.firstName.toString(),
            lastName: gr.lastName.toString()
        };

        var userDetailsString = JSON.stringify(usrobj);
        gs.log("SI_ReturnUserDetails - UserDetails: " + userDetailsString);

        return userDetailsString;
    },

    type: 'SI_ReturnUserDetails'
});

Client Script:

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

    var callerId = g_form.getValue('caller_id');
    g_form.addInfoMessage("Client Script - Caller ID: " + callerId);

    var ga = new GlideAjax('SI_ReturnUserDetails');
    ga.addParam('sysparam_name', 'returnDetails');
    ga.addParam('sysparam_caller_id', callerId);
    ga.getXML(displayUserDetails);

    function displayUserDetails(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        g_form.addInfoMessage("Client Script - Response: " + answer);

        var result = JSON.parse(answer);
        setFormValues(result);
    }

    function setFormValues(userDetails) {
        g_form.setValue('u_email', userDetails.email);
        g_form.setValue('u_firstname', userDetails.firstName);
        g_form.setValue('u_lastname', userDetails.lastName);
    }
}

@Kongaleti Navee Please update your client script as follows.

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

    var ga = new GlideAjax('SI_ReturnUserDetails');
    ga.addParam('sysparam_name','returnDetails');
    ga.addParam('sysparam_caller_id',g_form.getValue('caller_id'));
    ga.getXML(displayUserDetails);

    function displayUserDetails(response) {

        var answer = response.responseXML.documentElement.getAttribute("answer");
        alert(answer);

        var result = JSON.parse(answer);
        g_form.setValue('u_email',result.email);
        g_form.setValue('u_firstname',result.firstName);
        g_form.setValue('u_lastname',result.lastName);

    }

}

Hope this helps.

can any on please tell me where did i make the mistake

[Sandeep Rajput]

@Kongaleti Navee This is the line where you made the mistake in your client script.

 ga.addParam('sysparam_caller_id',g_form.getValue(caller_id));

You didn't use quotes while using the caller_id field. It should have been as follows.

 ga.addParam('sysparam_caller_id',g_form.getValue('caller_id'));

Hope this helps.
