jQuery：如果DIV包含（'text'），. attr是否为href？

Question

(Twitter) I am trying but not sure how to use this to .attr at beginning of links/A/href , if the element selected contains certain words:

 $(".tweet:contains('government','Anonymous')").each(function(){
   $old_url = $(this).attr('href');
   $new_url = 'http://blankrefer.com/?'+$old_url;
   $(this).attr('href',$new_url);
  });

This works but without text detection:

$("A").each(function(){
   $old_url = $(this).attr('href');
   $new_url = 'http://blankrefer.com/?'+$old_url;
   $(this).attr('href',$new_url);
});

You cannot pass multiple search strings to :contains , see this for more information. You can repeat the selector with another search string using comma separator as shown below.

 $(function(){ $(".tweet:contains('government'),.tweet:contains('Anonymous')").each(function(){ $old_url = $(this).attr('href'); alert($old_url); $new_url = 'http://blankrefer.com/?'+$old_url; $(this).attr('href',$new_url); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> <a class="tweet" href="gov">government one</a> <a class="tweet" href="ano">Anonymous one</a> <a class="tweet" href="gov2">govern two</a>
