jQuery(callback) → jQuery

Allows you to bind a function to be executed when the DOM document has finished loading. This function behaves just like $(document).ready(), in that it should be used to wrap other $() operations on your page that depend on the DOM being ready to be operated on. While this function is, technically, chainable - there really isn't much use for chaining against it. You can have as many $(document).ready events on your page as you like. See ready(Function) for details about the ready event.

Function callback : The function to execute when the DOM is ready.

Example:

Executes the function when the DOM is ready to be used.

$(function()

{ 

  // Document is ready

});

Example:

Uses both the shortcut for $(document).ready() and the argument to write failsafe jQuery code using the $ alias, without relying on the global alias.

jQuery(function($) {

// Your code using failsafe $ alias here...
});
