有关于特殊字符/实体和innerHTML的任何规则吗？ [英] Are there any rules regarding special characters/entities and innerHTML?

问题描述

当我从javascript中使用innerHTML时，浏览器（至少是Safari和Firefox）似乎用某些字符和数字实体替换它们的命名实体。

When I use innerHTML from javascript, the browser (Safari and Firefox at least) seem to replace certain characters and numeric entities with their named entities.

code> \ xa0 （非破坏性空格）将替换为& nbsp; ，
&＃60; （小于）将替换为& lt; 。但是例如，umlautü不会替换为& uuml; 。

The character \xa0 (non breaking space) gets replaced by  , < (lesser than) gets replaced by <. But for example the umlaut ü is not replaced with ü.

此行为。

一个简单的演示：

<h2 id="withoutnbsp">This does not use en be es pe (uses the \xa0 character)</h2>
<script>alert(document.getElementById("withoutnbsp").innerHTML);</script>

您可以使用gist页面上的raw链接，在浏览器中查看。

我需要知道替换。任何帮助是赞赏。谢谢。

I need to know exactly which characters innerHTML replaces. Any help is appreciated. Thanks.

推荐答案

HTML 5规范有一个规则用于在你调用innerHTML时序列化HTML片段， href =http://www.w3.org/TR/2009/WD-html5-20090212/serializing-html-fragments.html =nofollow noreferrer>序列化HTML片段（请注意innerHTML isn

The HTML 5 spec has rules for serializing an HTML fragment when you call innerHTML on it, documented here: Serializing HTML fragments (note that innerHTML isn't in the HTML 4 spec, so the HTML 5 spec is the current reference).

规格的TLDR版本：空格，尖括号，&符号，等号和符号双引号是调用innerHTML时唯一可以转义的字符。

TLDR version of the spec: Spaces, angle brackets, ampersands, equals signs and double quotes are the only chars that get escaped when innerHTML is called.
