Javascript RegEx报价 [英] Javascript RegEx quote

问题描述

我无法使这个Javascript正则表达式工作。
我想要的是找到一个以开头的字符@中间有任何字符，以结尾。我还需要一个单引号。

I'm having trouble getting this Javascript Regular Expression to work. What i want is to find a character that starts with @" has any characters in the middle and ends with ". I will also need it in a single quote from.

对我来说，棘手的部分是它不能以 @并以结尾，因为它正在查看的字符串看起来像 [UIImage imageNamed：@glass-round-red-green- button.png] 。

The tricky part for me, is that it cant be starting with @" and ending with " because the string it's looking through could look like [UIImage imageNamed:@"glass-round-red-green-button.png"].

到目前为止我所拥有的是这个。

So far what i have is this.

正则表达式：新的RegExp（'\\ @？\\w + \\b*'，'g'）

推荐答案

试试这个正则表达式：

/@(["'])[^]*?\1/g

解释：

• @（[']）匹配 @ 或 @'


• [^] *？匹配任意字符（ [^] 包含与相反的所有字符。不包含行-breaks），但是以非贪婪的方式


• \1 匹配相同的字符匹配（[']）

• @(["']) matches either @" or @'
• [^]*? matches any arbitrary character ([^] contains all characters in opposite to . that doesn’t contain line-breaks), but in a non-greedy manner
• \1 matches the same character as matches with (["'])

使用文字RegExp语法 / ... / 更方便。请注意，这不会将 \等序列转义为帐号。

Using the literal RegExp syntax /…/ is more convenient. Note that this doesn’t escape sequences like \" into account.
