Return value from a call back function

[Snow Tomcal]

Hi All,

I have a client script that use GlideAjax.

I want to return a value from the call back function, does anyone know how to implement this?

my script:

function funcationName (number) {

var ga = new glideAjax('ScriptName');

ga.addParam('sysparm_name', 'function_name');

ga.addParam('sysparm_number', number);

return gs.getXMLAnswer(callBackFunction);

}

function callBackFunction(response){

response = JSON.parse(response);

return response[0] == 'name' ? true : false;

}

Thanks In Advance 🙂

Hi ,

It's good first you create an exmp. as per doc.

https://docs.servicenow.com/en-US/bundle/utah-api-reference/page/app-store/dev_portal/API_reference/...

Use function like

var ga = new GlideAjax('HelloWorld'); // HelloWorld is the script include class 
ga.addParam('sysparm_name','helloWorld'); // helloWorld is the script include method 
ga.addParam('sysparm_user_name',"Bob"); // Set parameter sysparm_user_name to 'Bob' 
ga.getXML(HelloWorldParse);  /* Call HelloWorld.helloWorld() with the parameter sysparm_user_name set to 'Bob' 
      and use the callback function HelloWorldParse() to return the result when ready */

// the callback function for returning the result from the server-side code
function HelloWorldParse(response) {  
   var answer = response.responseXML.documentElement.getAttribute("answer"); 
    alert(answer);
}

The returned value is okay but when I try to use it in the original function it's value is undefined.

@Snow Tomcal 

whatever further processing you want to do after the ajax do it in callback method only.

What's the point in adding that logic outside the callback?

I'm using more than one GlideAjax so I want to combine the logic in the main function
