Whatever code you write inside the $(document ).ready() method will run once the page DOM is ready to execute JavaScript code.Example:You can try to run the following code to learn how to use $(document).ready() method in jQuery:

2) jQuery.hokdReady() :Holds or releases the execution of jQuery's ready event.Example:Delay the ready event until a custom plugin has loaded.$.holdReady( true ); $.getScript( "myplugin.js", function() {$.holdReady( false ); });

jQuery's ready is an event which gets triggered automatically when DOM is ready while holdReady is a signal/flag to hold this triggering. holdReady was included in 1.6 version and it works only if used before the execution/triggering of ready event. Once ready event is fired, it has nothing to do. It is useful in dynamically loading scripts before the ready starts. It release ready event execution when used with a true parameter.
