php采集页面

一般通过curl、file_get_contents来采集，如：

<code class="lang-php">$ch=curl_init($post_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; rv:24.0) Gecko/20100101 Firefox/24.0");
$con=curl_exec($ch);
</code>

js也能采集页面吗，有什么方法？

node+1，比如这货http://phantomjs.org/

js由于有跨域问题，是不能做采集任务的，不过你可以考虑下node.js
