Node.TEXT_NODE和IE7 [英] Node.TEXT_NODE and IE7

问题描述

  if（node.nodeType == Node） TEXT_NODE）{
  

当然，在Firefox，Safari和Opera中都可以正常工作。但Internet Explorer 7正在抱怨 Node （具有大写字母N）未定义。但这是 DOM Level 2 的一部分！ / p>

我真的需要更改我的代码才能使用魔术数字吗？或者我在这里缺少一些简单的东西？

解决方案

不幸的是，你没有丢失任何东西。

IE中没有Node常量。看这里 http://www.ibm.com/developerworks/xml/library /x-matters41.html 在你还能用DOM做什么？。

所以要么定义自己的Node常量，要么简单请求

  node.nodeType === 3 
  

I've some javascript that tests DOM node types against like this:

        if(node.nodeType == Node.TEXT_NODE) {

Of course, it all works fine in Firefox, Safari, and Opera. But Internet Explorer 7 is complaining that Node (with the capital N) is undefined. But that's part of DOM Level 2!

Do I really need to change my code to use magic numbers? Or am I missing something simple here?

解决方案

Unfortunately you are not missing anything.

There is no Node constant in IE. Look here http://www.ibm.com/developerworks/xml/library/x-matters41.html at section "What else can you do with the DOM?".

So either you define your own Node constant or you simply ask for

node.nodeType === 3
