Jsdom does not process script inside web page

I am new to nodejs. I want to use jsdom to parse some web pages that may contain script code inside. But I got an error indicating that the function or variable is not defined. Can someone give some guidance on this.

my code

var jsdom = require('jsdom');

jsdom.env({
  html: 'http://10.200.0.10:8080/test/a.html',
  scripts: [
    'http://code.jquery.com/jquery-1.5.min.js'
  ],
  done: function(errors, window) {
    var $ = window.$;
    window.onload();
    console.log(window.a);
  }
});

and html page here

<html>
<head>
    <script>
    var a = 0;
    function loads(){
        a=1000;
    }
    </script>
</head>
<body onload='loads()'>
</body>
</html>

and got an error message below

It is reported that the download function is not defined, but has actually been announced on the web page.

Can someone give some suggestions or just tell me that jsdom cannot handle scripts embedded in the page.

Here is the code you want to have:

var fs = require('fs');
var jsdom = require('jsdom');
var doc   = jsdom.jsdom(fs.readFileSync("a.html"), null, {
          features: {
            FetchExternalResources   : ['script'],
            ProcessExternalResources : ['script'],
            MutationEvents           : '2.0',
        }
    });

var window = doc.createWindow();
jsdom.jQueryify(window, "http://code.jquery.com/jquery-1.5.min.js", function() {
    console.log(window.a);
    console.log(window.$().jquery); //jquery version
});

Your code will not work because the method jsdom.envdoes not process scripts.

, npm request

:

var http = require('http'),
    jsdom = require('jsdom'), 
    request = require('request');

var server = http.createServer(function (request, response) {
    getPage("http://isohunt.com/torrents/?iht=-1&ihq=life+is+beautiful", function (body) {
        jsdom.env({
            html: body,
            scripts: ['http://code.jquery.com/jquery-1.6.min.js']
        }, function(err, window){
            var $ = window.jQuery;
            //your code goes here

        });
    })
});
server.listen(3000);

function getPage(someUri, callback) {
    request({uri : someUri}, function (error, response, body) {
       callback(body);
    });
}
