我有一个问题，用PhantomJS从这个链接中抓取链接

var page = require('webpage').create();
var url = '这里填写要抓取的链接';

page.open(url, function(status) {
  if (status === 'success') {
    var links = page.evaluate(function() {
      var results = [];
      var anchorElements = document.getElementsByTagName('a');
      for (var i = 0; i < anchorElements.length; i++) {
        results.push(anchorElements[i].getAttribute('href'));
      }
      return results;
    });

    console.log(links);
  }

  phantom.exit();
});

phantomjs 脚本文件名.js
