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

Let us assume we have a function in Script Include :

demofunction: function () {

var element = this.getParameter('sysparm_parameter');

return 'Hi, This is bind with answer atrribute';

}

Now in client script -

function myCallBack(response) {

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

alert(answer); // Output "Hi, This is bind with answer atrribute"

}

Here "response" is an XML document which contains an attribute "answer" and the value returned from the demofunction binded with the answer attribute.

So response.responseXML.documentElement.getAttribute("answer") gives us the value returned from the script include function.

Award Correct Answer if my Solution Works, Mark helpful if it helps...

This link should better explain you, check the GlideAjax section:

The response you get after a server side call(glideajax), will be stored in a format of XML.

You need to parse the response to get the answer attribute:

XML Hierarchy:

response -> responseXML -> documentElement -> Answer(place where the result are stored)

so gowrisankar,

response or answer is fixed keyword here or we can use any varaible name

Yes,

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

var answer -> is a variable you define, even you can define var result

response.responseXML.documentElement.getAttribute("answer"); -> here answer is a value in XML Tag that we receive after server call.
