[聚合文章] Zombie.js in node.js fails to scrape certain websites

The simple script below returns a bunch of rubbish. It works for most websites, but not william hill:

var Browser = require("zombie");
var assert = require("assert");

// Load the page from localhost
browser = new Browser()
browser.visit("http://sports.williamhill.com/bet/en-gb/betting/y/5/et/Football.html", function () {
browser.wait(function(){
console.log(browser.html());
});
});

run with node

output:

(actual output is much longer)

Anyone know why this happens, and specifically why it happens on the only site i actually want to scrape???

Thanks
