node.js全局模式，用于排除多个文件

或没有外部依赖项：

var fs = require('fs');var path = require('path');var walk = function (dir, regExcludes, done) {  var results = [];  fs.readdir(dir, function (err, list) {    if (err) return done(err);    var pending = list.length;    if (!pending) return done(null, results);    list.forEach(function (file) {      file = path.join(dir, file);      var excluded = false;      var len = regExcludes.length;      var i = 0;      for (; i < len; i++) {        if (file.match(regExcludes[i])) {          excluded = true;        }      }      // Add if not in regExcludes      if(excluded === false) {        results.push(file);        // Check if its a folder        fs.stat(file, function (err, stat) {          if (stat && stat.isDirectory()) { // If it is, walk again walk(file, regExcludes, function (err, res) {   results = results.concat(res);   if (!--pending) { done(null, results); } });          } else { if (!--pending) { done(null, results); }          }        });      } else {        if (!--pending) { done(null, results); }      }    });  });};var regExcludes = [/index.html/, /js/lib.js/, /node_modules/];walk('.', regExcludes, function(err, results) {  if (err) {    throw err;  }  console.log(results);});
