regex - Visual Studio 使用正则表达式和单/双引号查找和替换

Question

如何使用 VS Find/Replace 进行替换：

这: $('a[name="lnkFind"]').on('click', 函数

用这个： $(document).on("click", "a[name='lnkFind']", function

我不确定哪些字符需要转义 - 单引号或双引号或两者兼而有之？我尝试过的所有模式似乎都找不到匹配项。

Answer 1

您需要转义许多这些字符。

Find/Replace 会抱怨未转义的(and )，甚至是最后的裸露(，因为它缺少匹配的). 还有方括号，用于字符集，最后是$.

所以这应该作为模式工作：

\$\('a\[name="lnkFind"\]'\).on\('click', function

Answer 2

Except in special cases (such as vim regex), in general you can escape any and all special characters in regex to get their literal form, i.e. escaping a special character that doesn't need to be escaped, won't do any harm.

That said, here's the minimum that needs to be escaped:

\$\('a\[name="lnkFind"]')\.on\('click', function

I don't think you'll need to escape anything in the replacement, because only a $ or \ followed by a number will be interpreted.

Answer 3

您应该查看正则表达式中的特殊字符列表。

$, ., [,]都应该被转义。
