Is there any way to find any AJAX request is running on page (on $(window).load
event) ?
I want to apply some event when all ajax request completed.
I have tried
.ajaxStop(function(){ })
but I want to put this block( ajaxstop
) when AJAX request exist on page.
Any help would be appreciated.
Make sure this functions is the first thing loaded to the browser:
(function(open) {
XMLHttpRequest.prototype.open = function(method, url, async, user, pass) {
this.addEventListener("readystatechange", function() {
//Put your code here
}, false);
open.call(this, method, url, async, user, pass);
};
})(XMLHttpRequest.prototype.open);
Each time an ajax response is retrieve, the following listner functions is called, and is in there that you should put your code:
this.addEventListener("readystatechange", function() {
//Put your code
}, false);
Note: This code was extracted from this answer which was used to intercept all ajax requests and from this answer you don't need to pass the parameters on functions:
(function(open) {
XMLHttpRequest.prototype.open = function() {
this.addEventListener("readystatechange", function() {
// put your code here!
}, false);
open.apply(this, arguments);
};
})(XMLHttpRequest.prototype.open);
Put this at the beginning:
var ajax_running = false;
$(document).ajaxStart(function() {
ajax_running = true;
});
Then you can later use:
$(document).ready(function() {
if (ajax_running) {
$(document).ajaxStop(function() {
// do something
})
ajax_running = false;
}
});
You can do something like this, which creates a function that will tell you how many active requests are pending.
const activeAjaxRequests = (function(send) { var active_requests = 0; XMLHttpRequest.prototype.send = function(body) { active_requests++; this.addEventListener("readystatechange", function() { if(this.readyState === 4) active_requests--; }); send.call(this, body); }; return ()=>active_requests; })(XMLHttpRequest.prototype.send); var active_requests = activeAjaxRequests(); console.log(`There are currently ${active_requests} active ajax requests.`);
