Why do I see MS jQuery samples use `$(domReady); `?

问题

I don't know if anyone ELSE has noticed this, but I noticed the jQuery samples I see on MS tend to use a different format:

<script type="text/javascript">  

  $( domReady );  

  function domReady() {  
     $('#btn').click( showMessage );  
  }  

  function showMessage() {  
     $('#message').fadeIn('slow');  
  }  
</script> 

Isn't this the same as:

$(document).ready( function() {

  $('#btn').click( showMessage );  

  function showMessage() {  
     $('#message').fadeIn('slow');  
  }  

});

Is there any advantage of using one syntax over the other?

I will admit, the MS way does look cleaner.

回答1:

The only real difference is readability and organization.

It's technically the same as

$( function() {

  $('#btn').click( showMessage );  

  function showMessage() {  
     $('#message').fadeIn('slow');  
  }  

});

which is shorthand for $(document).ready(...)
