问题描述
尽管以下工作： http://jsfiddle.net/N7D5r/
我试图用同样的code 不正确获得冠军。他们返回null，不管是什么奇怪的原因：
My attempt at using the same code does not correctly get the titles. They return null, for whatever strange reason:

$(document).ready(function(){
// Act on each link
$('a').each(function(eachIteration){
// Store current link's url
var url = $(this).attr("href");
$.get(url, function(response){
alert("This is the url: " + url);
if (((/<title>(.*?)<\/title>/m).exec(response)) != null)
alert("This would be the title: " + (/<title>(.*?)<\/title>/m).exec(response)[1]);
else
alert("title was null");
});
});
});
</script>
<title>test</title>
</head>
<body>
<p><a href="javascript:;">Javascript link</a></p>
<p> <a href="http://www.latentmotion.com">Misc. Link</a> and what else... <a href="http://www.latentmotion.com/how-to-create-a-jquery-bookmarklet/#comment-52004762">jQuery Bookmarklet Link</a></p>
<p> Some <a href="#test">anchor link</a> test.</p>
