在下面的代码中,我遍历所有目录和任何扩展名为“js”的文件,我将其添加到“files_”数组中。 我想要做的是,创建一个对象或方法“accumulateData”,每次调用“files_.push”时都会更新。这样,对于每次迭代,都是如此 调用“files_.push”,“accumulateData”将包含“files_.push”和totalsize的最新/更新内容。
此外,我希望下面的方法返回“accumulateData”,这样在“getFiles”方法完成迭代后,我可以调用类似的东西,
console.log(accumulateData.totalSize)
请让我知道如何实现
码:
function getFiles(dir, files_) {
files_ = files_ || [];
var files = fs.readdirSync(dir);
for (var i in files) {
var name = dir + '/' + files[i];
if (fs.statSync(name).isDirectory()) {
getFiles(name, files_);
} else if (name.endsWith('js')) {
//totalSize += fs.statSync(name).size;
files_.push({ name: name, size: fs.statSync(name).size });
/*accumulateData(files, totalSize)
{
files = files;
totoalSize = totalSize;
}*/
}
}
return files_;
//return accumulateData
}
我的尝试
let totalSize = 0;
let accumulatedData;
function getFiles(dir, files_) {
files_ = files_ || [];
const files = fs.readdirSync(dir);
for (const i in files) {
const name = dir + '/' + files[i];
if (fs.statSync(name).isDirectory()) {
getFiles(name, files_);
} else if (name.endsWith('js')) {
// files_.push(name);
totalSize += fs.statSync(name).size;
files_.push({ name: name, size: fs.statSync(name).size });
// data(files, totalSize);
accumulatedData = {
files: files,
totalSize: totalSize
};
}
}
return accumulatedData;
}
console.log(getFiles('/home/bakria/Projects/smartvehicle').totalSize);
答案 0 :(得分:2)
您可以使用包含文件数组和总大小的对象:
function getFiles(dir, obj) {
obj = obj || { files: [], totalSize: 0 }; // if no object is provided then initialize obj with an object that contains an empty array for files and 0 for totalSize
var files = fs.readdirSync(dir);
for(var i = 0; i < files.length; i++) {
var name = dir + '/' + files[i];
var stat = fs.statSync(name); // to minimize the calls to fs.statSync
if (stat.isDirectory()) {
getFiles(name, obj); // pass obj to getFile (recursion)
} else if (name.endsWith('js')) {
obj.totalSize += stat.size; // add this file's size to obj.totalSize
obj.files.push({ name: name, size: stat.size }); // push this file's object into obj.files
}
}
return obj; // return obj
}
回报将是这样的:
var result = getFiles("some/dir");
其中result
是:
{
files: [/* an array of files */],
totalSize: /* total size of the files */
}
因此result.files
将是文件数组,result.totalSize
将是总大小。
