This method brings a lot of consistency to the API, and we recommend that you use this method, as it simplifies the jQuery code base. As of jQuery version 1.7, the on () method is the new replacement for the bind (), live () and delegate () methods. : The state information is invalid for this page and might be corrupted. The on () method attaches one or more event handlers for the selected elements and child elements. in your case this might be before the ready event is called, thus rendering your handler to load (which is appended after document.ready) useless.

Note that you’ll also have to check the readyState in this solution, like explained above, to make sure the callback will still be executed even if the event has already fired.In general, jQuery has made Ajax very easy by providing low-level interface, shorthand methods and helper functions, which all gives us great features of handling Ajax requests in our ASP.NET Webs. The jQuery Load method is the simplest yet powerful enough to fulfill all your AJAX requirements. This also results in a time delay, as it’ll wait for all assets to be loaded. ready() tutorial $ ( function ( ) ) Īlternatively you could use the load event, like jQuery does, as this will work in any browser. But what does this mean? When you’re executing JavaScript code inside the section of an HTML document then this would make sure that the code is executed when the browser has loaded all following elements (e.g. The ready method makes sure that code is only executed when all DOM elements are safe to be manipulated.
