I want to check whether $(function(){ }); is "ready".

Return true if DOM is ready, false otherwise

Answer 1

From jQuery code

if ( jQuery.isReady ) {  
    fn.call( document, jQuery );
} 

Answer 2

You can use the explicit call

$(document).ready(function(){
  // do this after dom is ready
});

Or use the shortcut

$(function(){
  // do this after dom is ready
});

It's also useful to wrap your jQuery in an anonymous function when you're using other libraries; Also very common to use this when writing jQuery plugins.

(function($, window){
  // use $ here freely if you think any other library might have overridden it outside.
  $(function(){
    // do this after dom is ready
  });
})(jQuery, window);

Lastly, you can use jQuery.isReady (bool)

if (jQuery.isReady) {
  // do something
}
