JSDOM in nodeJS: How do I get back the manipulated html?
提问by Guy
I am trying to manipulate a remote HTML and return it manipulated. I decided to use JSDOM but cannot figure out how to get the manipulated HTML back. Any ideas?
我正在尝试操作远程 HTML 并将其返回操作。我决定使用 JSDOM，但无法弄清楚如何恢复被操纵的 HTML。有任何想法吗？
jsdom.env({
url: "http://www.cnn.com",
scripts: ["http://code.jquery.com/jquery.js"],
done: function (err, window) {
var $ = window.$;
console.log("HN Links");
var src = $(".ghciTopStoryImage1 img").attr('src','http://lorempixel.com/396/220/');
var headline = $(".blkbigheader span").html('header');
var description = $(".blkbigheader").parent().find("p a:eq(0)").html('text');
// not working....
content =$(window.document).html();
}
});

var JSDOM = require("jsdom").JSDOM;
var jsdom = new JSDOM("<!DOCTYPE html>hello");
jsdom.serialize() === "<!DOCTYPE html><html><head></head><body>hello</body></html>";
doc.documentElement.outerHTML === "<html><head></head><body>hello</body></html>";
Adapting your above example would then just be content = jsdom.serialize().
调整你上面的例子就可以了content = jsdom.serialize()。

sometimes jQuery isn't the answer
有时 jQuery 不是答案
content = window.document.documentElement.outerHTML;
