get value from call back function

[amaradiswamy]

Hi All,

I am using a glideajax call to script include to check for the class, now i need to return the answer from call back function.

So in the below script i need to get the value in check from call back function, without writing my next code in the call back function. But, i am not able to return the value as we cannot return from an asynchronous call inside a synchronous method.

var ga = new GlideAjax("XYZ");

  ga.addParam("sysparm_name","getClass1");

  ga.addParam("sysparm_CIName",g_form.getValue('cmdb_ci'));

  ga.getXML(ajaxResponse);

function ajaxResponse(serverResponse) {

var check = false

  var typeofRequest = serverResponse.responseXML.getElementsByTagName("Type");

var ciclass = typeofRequest[0].getAttribute('superclass1');

  if(ciclass != 'BusSv Names')

  {

check = true;

  }

}

Please suggest on a simple way to get the value from callback function.

Thanks and regards,

Swamy

I'm not sure if this will help but first these are my assumptions:

1) This script is in a client script. I think that because I see the use of g_form.getValue()

2) Although the next part of your script is desired to be outside of the callback it sounds like it's still dependent upon the answer that's returned from the callback

In that scenario the script that is outside of the callback I would write within a function and call that function inside the call back.

var ga = new GlideAjax("XYZ");

ga.addParam("sysparm_name","getClass1");

ga.addParam("sysparm_CIName",g_form.getValue('cmdb_ci'));

ga.getXML(ajaxResponse);

function ajaxResponse(serverResponse) {

var check = false

var typeofRequest = serverResponse.responseXML.getElementsByTagName("Type");

var ciclass = typeofRequest[0].getAttribute('superclass1');

if(ciclass != 'BusSv Names')

{

check = true;

}

if(check){

outsideScript();

}

}

function outsideScript(){

// do my stuff here

}

Or you could get rid of "check" and just use your first condition statement. Or you could pass the check variable to the outside function.

...

    outstideScript(check);

...

function outsideScript(check){

if(check == 'true'){

//do stuff here

}

}

You can write your code in the callBack function itself.
