$（* [attr]）和$（[attr]）之间的差异

Question

I just want to know which one is preferable in the following $(*[attr]) and $([attr]) . Why?

Because both are doing same.

 $('[onclick]').each(function(i,elem){ console.log(elem.onclick); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script> <div onclick="asd()"></div> <div onclick="def()"></div> <div id="dv1"></div> <div id="dv2"></div> 

 $('*[onclick]').each(function(i,elem){ console.log(elem.onclick); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script> <div onclick="asd()"></div> <div onclick="def()"></div> <div id="dv1"></div> <div id="dv2"></div> 

And also what about the browser support.

Apologize if i asked the duplicate one.

Answer 1

I think Both are same in behavioral level.

As @satpal said in comment.

I tried in jsPref, It says $('*[onclick]') is the fastest.

Thanks @satpal
