RegExp 用于干净的文件和文件夹名称

Question

I'm building a File manager with jQuery. Users can create folders and upload files. I need a Regual Expression (javascript) to check if the entered folder-name or the uploaded file-name is web-save. (no special chars or spaces are allowed)

The name should only contain alphanumeric values (az,AZ,0-9), underscores (_) and dashes(-)

Answer 1

Don't bother your visitor, do it for him :)

var cleanName = function(name) {
    name = name.replace(/\s+/gi, '-'); // Replace white space with dash
    return name.replace(/[^a-zA-Z0-9\-]/gi, ''); // Strip any special charactere
};

cleanName('C\'est être');

Answer 2

This seems quite straightforward:

/^[\w.-]+$/

Answer 3

function clean(filename) {
filename= filename.split(/[^a-zA-Z0-9\-\_\.]/gi).join('_');
return filename;
};

filename=clean("Vis'it M'ic ro_pole!.pdf");

Answer 4

This a regex to sanitize Windows files/folders. It will work for POSIX (linux, mac) too since it's less restrictive.

 function sanitizePath (path) { return path.replace(/[\\\\/:*?"<>|]/g, '') } console.log(sanitizePath('\\\\x/:a*b?<>|y'))
