nodejs文件夹遍历模块

自己捣鼓nodejs玩的,

顺便记录下

模块js

var fs = require('fs');

/*

递归处理文件,文件夹

path 路径
floor 层数
handleFile 文件,文件夹处理函数

*/

function walk(path, floor, handleFile) {
handleFile(path, floor);
floor++;
fs.readdir(path, function(err, files) {
if (err) {
console.log('read dir error');
} else {
files.forEach(function(item) {
var tmpPath = path + '/' + item;
fs.stat(tmpPath, function(err1, stats) {
if (err1) {
console.log('stat error');
} else {
if (stats.isDirectory()) {
walk(tmpPath, floor, handleFile);
} else {
handleFile(tmpPath, floor);
}
}
})
});

}
});
}

exports.walk = walk;

var dirWalker = require('./dirWalker');
var fs = require('fs');

function handleFile(path, floor) {
var blankStr = '';
for (var i = 0; i blankStr += '    ';
}

fs.stat(path, function(err1, stats) {
if (err1) {
console.log('stat error');
} else {
if (stats.isDirectory()) {
console.log('+' + blankStr + path);
} else {
console.log('-' + blankStr + path);
}
}
})


}

dirWalker.walk('E:/temp', 0, handleFile);
