NodeJS下创建多级目录
var path = require('path');
var fs = require('fs');
var mkdir_p = function (dirpath, mode, callback) {
fs.exists(dirpath, function (exists) {
if (exists) callback && callback(dirpath);
else mkdir_p(path.dirname(dirpath), mode, function () {
fs.mkdir(dirpath, mode, callback);
});
});
};
mkdir_p('c/d/');
