Phantomjs Function.prototype.bind [英] Phantomjs Function.prototype.bind

问题描述

是的，我知道. Phantomjs不支持函数绑定.但是也许我可以使用其他东西，或者说page.open不使用bind?好像还可以，但是有些网站 返回错误

Yes, I know that. Function bind is not supported by Phantomjs. But maybe I can use something else, or say page.open not to use bind? It seems to be OK, but some websites return error

TypeError: 'undefined' is not a function (evaluating 'b.bind(a)')

之后，我写了一个简单的脚本，它只打开一个页面:

After that I wrote a simple script, which just opens a page:

var address = phantom.args[0];
if(!address) phantom.exit(1);

page = require("webpage").create();

page.open(address, function(status){
setInterval(
   function () {

   console.log(
       page.evaluate(function() {
            return document.body.innerHTML.length;
       })
   )}, 200)
})

但是错误仍然存​​在.错误不是主要问题，但问题是获取页面内容，因为错误后页面内容未加载...

But error is still there. Error is not the main problem, but the problem is to get page content, because after error page content is not loading...

所以，我需要帮助.

推荐答案

有一个 npm软件包，为phantomJS缺少的.bind方法加载一个polyfill .为了方便起见，在此处复制安装说明，但请单击链接获取任何更新.

There is an npm package which loads a polyfill for phantomJS's missing .bind method. Copying the installation instructions here for convenience, but follow the link for any updates.

安装

npm install --save-dev phantomjs-polyfill

用法

require('phantomjs-polyfill')

与业力一起使用 将polyfill直接包含在karma.conf的文件列表中.

Usage with Karma Include the polyfill directly in the files list of your karma.conf

...
files: [
  './node_modules/phantomjs-polyfill/bind-polyfill.js',
  ...
]
...
