Hello,
I have a catalog client script where I make three glideajax calls (asynchronous).
var ga1=new GlideAjax("PUtilsAjax");
ga1.addParam("sysparm_name", "region1");
ga1.addParam("sysparm_vs_token", token);
ga1.getXML(callback1);
var ga2=new GlideAjax("PUtilsAjax");
ga2.addParam("sysparm_name", "region2");
ga2.addParam("sysparm_vs_token", token);
ga2.getXML(callback2);
var ga3=new GlideAjax("PUtilsAjax");
ga3.addParam("sysparm_name", "region3");
ga3.addParam("sysparm_vs_token", token);
ga3.getXML(callback3);
function callback1(response){
var answerStr = response.responseXML.documentElement.getAttribute("answer");
var ans = JSON.parse(answerStr);
console.log("answer region1");
console.log(ans);
}
function callback2(response){
var answerStr = response.responseXML.documentElement.getAttribute("answer");
var ans = JSON.parse(answerStr);
console.log("answer region2");
console.log(ans);
}
function callback3(response){
var answerStr = response.responseXML.documentElement.getAttribute("answer");
var ans = JSON.parse(answerStr);
console.log("answer rehion3");
console.log(ans);
}
// I want the logic below to be executed ONLY IF I have the responses from the three asynchronous glide ajax calls
// some logic ++
My first question is: Are these calls in reality asynchronous?? Because even if the third call lasts 3 sec and the first call lasts 20 sec, the third callback is executed after the first one. Do I miss something here?
My second question is: How I can execute some logic ONLY IF I have the responses from the three asynchronous calls??
I would be grateful for your assistance.
Smith.
