Articles about ajax

Asynchronous programming is an essential aspect of JavaScript, allowing developers to handle time-consuming tasks without blocking the execution of other code. Traditionally, JavaScript used callback functions to manage asynchronous operations. However, callbacks can lead to callback hell and make code difficult to read and maintain.

JavaScript has many built-in functions that allow you to create custom events. In this article, we'll take a look at some of these functions and see what they do.

Are you confused why you are getting this error? This error is caused when you are trying to perform an AJAX call from one site to a different site. Because Javascript is a client-side application it requires additional security to help protect the users from malicious code, e.g. calling a different site without the user knowing.

The JsHelper in CakePHP 2.x has replaced the AjaxHelper from CakePHP 1.x. I recently tried to implement the JsHelper without very much success; perhaps if I would have read the documentation more closely it would have been quite obvious what my mistake was. So in case you're like me and often skim over long documentation of a helper when you just need one function, in my case: $this->Js->submit() then you can often miss very important information. This article will hopefully help clarify

it. If you want to further enhance some stuff I highly recommend Organizing data with the jQuery Sortable plugin.
