Is there a difference between $().ready() and $(document).ready()

我正在尝试为页面设置 jquery ui 选项卡，并且我使用了

$(document).ready(function(){
    $('#tabs').tabs();
});

这不起作用。所以我检查了他们的示例，发现现在可以使用不同的语法

$(function(){
    $('#tabs').tabs();
});

这两种语法有什么区别？

它们是等效的。 http://api.jquery.com/ready/

The .ready() method is typically used with an anonymous function:

$(document).ready(function() {
  // Handler for .ready() called. 
});

Which is equivalent to calling:

$(function() {  
  // Handler for .ready() called. 
});

If .ready() is called after the DOM has been initialized, the new handler passed in will be executed immediately.
