Gs object not working in client script

[naziya]

I am trying to use GS object in my client script but I am getting the error :-

'The object "gs" should not be used in client scripts'

How can I use gs in my script?

gs is documented here:

GlideSystem - ServiceNow Wiki

[loudari_karim]

The GlideAjax class allows the execution of server-side code from the client. GlideAjax calls pass parameters to the script includes, and, using naming conventions, allows the use of these parameters.

See GlideAjax - ServiceNow Wiki  

var HelloWorld = Class.create();

HelloWorld.prototype = Object.extendsObject(AbstractAjaxProcessor, {

  helloWorld: function() {

    return gs.example();

    }

});
