Usage and Syntax of .load()

The .load() jQuery method attached an event handler that executed a function when the specified element was fully loaded. Using the example below, an alert would have popped up when the page finished loading:

$("window").load(function(
{
	alert("The window has loaded!");
});

As you can see, the jQuery .load() function followed rather simple syntax:

$("selector").load(function);

Basically, jQuery .load() was a shortcut for using the .on() method with its parameters defined as "load", handler. You can still use this syntax to achieve the same result.

Note: the jQuery .load() method was deprecated in jQuery 1.8 and removed completely in jQuery 3.0.

Don't Get Mixed Up: .load() by AJAX

You cannot use the jQuery .load() method for event handlers now. However, you can use a method with the same name to get data from a server. While the name might add to confusion, this .load() is actually an AJAX method.

Before the event handling .load() method was removed, jQuery chose which of the two to execute based on the defined arguments. The currently unsupported method took just one (function), and the AJAX method takes three (a required URL, plus the optional data and callback).
