Question

我正在尝试下载包含一些javascript的完整网站数据，然后再将其下载到最终的视频目标，但是从输出屏幕截图看来，它正卡在javascript首次加载的位置。有没有必要让我超越javascript的东西的选项？我给它30秒的加载时间，但仍然没有这样做。谢谢

var page = new WebPage()
var fs = require('fs');

page.open("https://mywebsite.com");
page.onLoadFinished = function(status) {
      setTimeout(30000);
      console.log("page load finished");
      page.render('export.png');
      fs.write('1.html', page.content, 'w');
      phantom.exit();
};

这是错误；

 TypeError: undefined is not a constructor (evaluating 'Number.isNaN(s)')
