在本地部署脚本时收到错误

标签： javascript jquery

当我在IE8中解码此代码时

<script type="text/javascript" charset="utf-8" src="http://static.polldaddy.com/p/5968383.js"></script>
<noscript><a href="http://polldaddy.com/poll/5968383/">This is a test question ?</a></noscript>

并作为本地文件运行我收到此错误：

当我将这个页面放到服务器上，或者使用chrome或firefox本地运行时，它似乎工作正常，当我尝试在本地运行时，它是否可以阻止某些内容？

这是正在导入的6343643.js，因为问题字符限制而截断了一些代码：

答案 0 :(得分：0)

以下片段失败：

if(typeof _container!=="undefined"||_container!==null){_container.appendChild(h)}else{document.body.appendChild(h)}

条件是多余的（因为它的部分是互斥的）;它总是会导致true（因此永远不会执行else部分），因为有3个选项：

  1. _container === undefined。在这种情况下，typeof _container!=="undefined"为false，_container!==null为true，因此组合表达式为true。
  2. _container === null。在这种情况下，typeof _container!=="undefined"为真，_container!==null为false，因此组合表达式为真。
  3. 在所有其他情况下，typeof _container!=="undefined"和_container!==null都为真，因此组合表达式为真。

    4. 可能你打算写

    if(_container){_container.appendChild(h)}else{document.body.appendChild(h)}

    此外，最好向人们展示您的非缩小版JS代码;通过调试更容易。
