如何检索DOM文本节点的文本？ [英] How to retrieve the text of a DOM Text node?

问题描述

对于DOM中的给定Text节点，可以使用这些属性之一来检索其文本：

• textContent
• 数据


• nodeValue


• 全文






但是要使用哪一个？ =哪一个是最可靠和跨浏览器...





（如果多个属性是100％可靠和跨浏览器，那么哪一个最适合？ ）





---





更新：





实际上， wholeText 不是一个选项，因为它返回文本节点和所有兄弟文本节点的连接文本...

解决方案

nodeValue 应该是跨浏览器兼容的。 它是原始DOM 2级规范的一部分。





还可以看看 quirksmode.org的兼容性表（这是我经常用来查看哪些浏览器支持哪些属性）。




For a given Text node in the DOM, one can use one of these properties to retrieve its text:

• textContent
• data
• nodeValue
• wholeText

But which one to use? = which one is the most reliable and cross-browser...

(If multiple properties are 100% reliable and cross-browser, then which one would be most appropriate?)

---

Update:

Actually, wholeText is not an option since it returns the concatenated text of the text node and all sibling text nodes...

解决方案

nodeValue should be is cross-browser compatible. It is part of the original DOM Level 2 specification.

Also have a look at the compatibility table of quirksmode.org for that matter (that's what I always use to see which properties are supported by which browsers).
