从文件名中删除非法字符但保留空格 [英] Remove illegal characters from a file name but leave spaces

问题描述

我有以下代码行来删除文件名中的非法字符:

I have the following line of code to remove illegal characters from a file name:

str= str.replace(/([^a-z0-9]+)/gi, '-');

这工作正常，但它也删除了空格，我怎样才能只删除非法字符而保留空格?

That works fine but it also removes the spaces, how can I only remove the illegal characters but leave the spaces?

推荐答案

列出非法字符 在这里.要替换它们，请使用此正则表达式 /[/\\?%*:|"<>]/g 像这样:

Illegal characters are listed here. To replace them use this regex /[/\\?%*:|"<>]/g like this:

var filename = "f?:i/le>  n%a|m\\e.ext";

filename = filename.replace(/[/\\?%*:|"<>]/g, '-');

console.log(filename);
