š¤ How to cancel/abort jQuery AJAX request?
š Hey there tech-savvy folks! Have you ever encountered a situation where you need to cancel or abort an ongoing AJAX request? Well, worry not, because I've got you covered! In this blog post, we'll address this common issue and provide you with some easy solutions. So let's dive right in! šŖ
š§ The Problem: Aborting an ongoing AJAX request
The scenario is this: You have an AJAX request that needs to be made every 5 seconds. However, if the previous request has not completed yet, you need to abort that request and make a new one. But how do you tackle this problem? Let's take a look at the code snippet provided to get a better understanding.
$(document).ready(
var fn = function(){
$.ajax({
url: 'ajax/progress.ftl',
success: function(data) {
//do something
}
});
};
var interval = setInterval(fn, 500);
);
š The Solution: Aborting AJAX Request
To abort an ongoing AJAX request, you can make use of the jqXHR
object returned by the $.ajax()
method. This object provides a abort()
method that allows you to cancel the request. You can store this jqXHR
object in a variable and use it to abort the previous request before making a new one in the next interval. Let me show you how it can be done.
$(document).ready(
var xhr; // Define a variable to store the jqXHR object
var fn = function(){
if (xhr) {
// Abort the previous request if it exists
xhr.abort();
}
xhr = $.ajax({
url: 'ajax/progress.ftl',
success: function(data) {
//do something
}
});
};
var interval = setInterval(fn, 500);
);
š Problem Solved! You're a Pro now!
And there you have it! With a few simple lines of code, you can now cancel or abort an ongoing AJAX request and make a fresh one without any hassle. šŖ
