带有node.js的jQuery用于简单的事情

Question

I installed jquery with : npm install jquery and then tried to run:

var $ = require('jquery');
console.log($('<a href="">hkjhjkh</a>').text());

I get this error, that I understand very well (no document in node.js!) :

Error( "jQuery requires a window with a document" )

How to make jQuery work without a document / window in node.js in such a simple case?

---

PS: I tried with: var $=require('jquery')(jsdom.jsdom().createWindow()); , but unfortunately npm install jsdom gave me lots of make errors that I was unable to debug (that would be another question, so out of topic here).

Try cheerio ( https://github.com/cheeriojs/cheerio ):

Fast, flexible, and lean implementation of core jQuery designed specifically for the server.

Your code would look like this:

var cheerio = require('cheerio'),
    $ = cheerio.load('<a href="">hkjhjkh</a>');

console.log($('a').text());
