HTML5输入模式搜索报价 [英] HTML5 input pattern search for quote
问题描述
我需要对这个正则表达式测试一个输入字段(< input type =text/>
):
I need to test an input field (<input type="text" />
) against this regex:
[^'"]+
显然不是一件容易的事,因为我不能在属性中使用。使用实体似乎不起作用,因为它被字面引用的正则表达式引擎解释。
This obviously is no easy task as I cannot use "
inside the attribute. Using the quot entity does not seem to work as it gets interpreted literally by the regex engine.
我该如何做到这一点?
推荐答案
HTML5 @pattern属性正则表达式基于JavaScript正则表达式,因此您可以使用十六进制表示法或 unicode表示法你可以在JavaScript中使用该字符:
The HTML5 @pattern attribute regex is based on JavaScript regex, so you can use hexadecimal notation or unicode notation for that char as you would in JavaScript:
" = \x22 OR \u0022
' = \x27 OR \u0027
让您可以轻松使用
So that you can easily use
pattern="[^'\x22]+"
TADA!没有涉及JavaScript库!;)
TADA! No JavaScript libraries involved! ;)
