Node.JS循环删除非空文件夹及子目录下的所有文件

var fs  = require('fs')var path = require('path')var remove = function(tarPath, cb, removeStates) { if (!removeStates) {  removeStates = { cur: 0, all: 0 } } else {  if (!removeStates.cur) {   removeStates.cur = 0;  }  if (!removeStates.all) {   removeStates.all = 0;  } } removeStates.all++; fs.stat(tarPath, function(err, states) {  removeStates.cur++;  if (err) {   cb && cb()   return  }  if (states.isDirectory()) {   fs.readdir(tarPath, function(err, files) {    if (err) {     console.log(err)     cb && cb()     return    }    if (files.length < 1) {     fs.rmdir(tarPath, cb)     return    }    var count  = 0    var checkEnd = function() {     if (++count == files.length) {      fs.rmdir(tarPath, cb)     }    }    files.forEach(function(file) {     remove(path.join(tarPath, file), checkEnd, removeStates)    })   })  } else {   fs.unlink(tarPath, function(err) {    if (err) {     console.log(err)    }    cb && cb()    return   })  } }) return removeStates}

var states = remove('./testdir', function() {  console.log('delete complete')  clearInterval(checkTimer)});var checkTimer = setInterval(function() {  console.log(states)}, 500);

node remove.js{ cur: 546, all: 546 }delete complete
