How to return GlideAjax value

[Muhammad Arif B]

Hi, I have UI Action where need to display alert of based on resp value. But the problem cant get the value from mycallback function, Here my script :

function closeComplete(){
         if (checkFile() == "1"){
              alert("reason A");
         } else if (checkFile() == "0"){
             alert("reason B");
         }else{
             return false;
         }
}


function checkFile() {
        sys_id = g_form.getUniqueValue();
	
	var ga = new GlideAjax('AjaxFSMClosureValidation');
	ga.addParam('sysparm_name', 'callFuntionFileValidate');
	ga.addParam('sys_id', sys_id);
	ga.getXML(mycallback);

	function mycallback(response) {
		var resp = response.responseXML.documentElement.getAttribute('answer');
		return resp;
	}
	return mycallback;
}

Is there any way to get the value of resp and return to function closeComplete?

Hi @Muhammad Arif B,

function checkFile() {
         var sysID = g_form.getUniqueValue();// variable was not declared
	
	var ga = new GlideAjax('AjaxFSMClosureValidation');
	ga.addParam('sysparm_name', 'callFuntionFileValidate');
	ga.addParam('sysparm_sys_id', sysID);// it should always start 'sysparm' and also avoid predefined keyword in snow like sys_id and change the sysparm_sys_id in script include where you getting the value this.getParameter('sysparm_sys_id');
	ga.getXML(mycallback);

	function mycallback(response) {
		var resp = response.responseXML.documentElement.getAttribute('answer');
		return resp;
	}
	return mycallback;
}

Please try this code as per updated one.

Hi @Muhammad Arif B ,

try :

function checkFile(callback) {
    var sys_id = g_form.getUniqueValue();

    var ga = new GlideAjax('AjaxFSMClosureValidation');
    ga.addParam('sysparm_name', 'callFuntionFileValidate');
    ga.addParam('sys_id', sys_id);
    ga.getXML(function(response) {
        var resp = response.responseXML.documentElement.getAttribute('answer');
        callback(resp);
    });
}

checkFile(function(response) {  
    console.log(response);
});

Hi @Muhammad Arif B 
You cannot return from an asynchronous call inside a synchronous method
You need to bring you if/else statement to "mycalback" function

function mycallback(response) {
    var resp = response.responseXML.documentElement.getAttribute('answer');
     if (resp == "1"){
          alert("reason A");
     } else if (resp == "0"){
         alert("reason B");
     }
}

Hi @Muhammad Arif B,

function closeComplete(){
         if (checkFile() == "1"){
              alert("reason A");
         } else if (checkFile() == "0"){
             alert("reason B");
         }else{
             return false;
         }
}


function checkFile() {
        sys_id = g_form.getUniqueValue();
	
	var ga = new GlideAjax('AjaxFSMClosureValidation');
	ga.addParam('sysparm_name', 'callFuntionFileValidate');
	ga.addParam('sys_id', sys_id);
	ga.getXML(mycallback);

	function mycallback(response) {
		var resp = response.responseXML.documentElement.getAttribute('answer');
               alert('Script inlcude answer' + resp); //check what is returning 
		return resp; 
	}
	
}

Note:  no need to write return mycallback; as you are already retuning resp and after Return no code will run so try the above and let me know if it doesnt work  ?
