Allow "/" forward slash in regular expression
提问by webdev5
var patt = /^(?=.*[a-zA-Z0-9.!@#&*\-\u0080-\u052F])[a-zA-Z0-9\s.!@#&*',\-\u0080-\u052F]*$/;
console.log(patt.test("\u002f"));
I know that u002f is a forward slash in Unicode. I've tried adding that to the pattern as well as "/" and haven't been able to get it to log true yet.
我知道 u002f 是 Unicode 中的正斜杠。我已经尝试将它添加到模式以及“/”中，但还没有能够让它记录为真。

You can escape a /character, by using \/.
您可以/使用来转义字符\/。
Using unicode will actually result in the absolute sameresult, as using the character itself - and therefore will not solve your problem.
使用 unicode 实际上会产生与使用字符本身完全相同的结果 - 因此不会解决您的问题。

It is easy to add a forward slash, just escape it. No need using any character references or entities.
添加正斜杠很容易，只需将其转义即可。无需使用任何字符引用或实体。
var patt = /^(?=.*[a-zA-Z0-9.!@#&*\-\u0080-\u052F])[\/a-zA-Z0-9\s.!@#&*',\-\u0080-\u052F]*$/;

alert(patt.test("/test"));
