在保存的DOM上使用jQuery作为命令行

Question

This is something along the lines of what I'd like to do,

web_page = fetch("http://www.google.com")
console.log($(web_page).find("body"))

via a simple command line. So in a nutshell, save a webpage and then query that page using jQuery.

Are there any tools like this available?

Answer 1

try phantomjs , a headless webkit solution

Answer 2

If you're willing to do this in a browser, try using YQL or your own proxy to get around cross domain ajax issues, fetch the remote page via ajax and then traverse the response.

F.ex using something like https://github.com/padolsey/jQuery-Plugins/tree/master/cross-domain-ajax/

You can do

$.get('http://google.com', function(html) {
    console.log( $(html).find('body') );
});​​​​​​​​​​​​​​
