嵌入式javascript中的特殊字符 [英] special characters in embedded javascript
问题描述
我有一些像这样嵌入到 html 文件中的 javascript
I have some javascript that is embedded in the html file like this
<html>
<head>
<script>
// and the script runs here
</script>
</head>
<body></body>
</html>
它有一条这样的线
if((os == 'Mac')&&((br == 'Safari')||(br == 'Chrome')))
一切正常(这意味着脚本可以正常工作)，但是验证器在尖叫:
Everything goes OK (which means the script works), but the validator is screaming:
... 字符&"是分隔符的第一个字符，但作为数据出现
...在以下几种情况下可能会出现此消息:
- 您试图包含<"页面中的字符:您应该将其转义为<"
- 您使用了未转义的&符号&":这在某些情况下可能有效，但建议使用&"，这始终是安全的.
- 另一种可能是您忘记关闭前一个标签中的引号.
... character "&" is the first character of a delimiter but occurred as data
... This message may appear in several cases:
-You tried to include the "<" character in your page: you should escape it as "<"
-You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&", which is always safe.
-Another possibility is that you forgot to close quotes in a previous tag.
替换所有 & 似乎很荒谬与 &.我怎样才能摆脱那个错误?
It seems ridiculous to replace all & with &. How can I get rid of that error?
推荐答案
如果您使用 XHTML，则需要将内联脚本包含在 CDATA 部分:
If you are using XHTML, you need to enclose your inline scripts within a CDATA section:
<script type="text/javascript">
// <![CDATA[
document.write("&");
// ]]>
</script>
