js怎么读取服务器里的txt内容到变量，然后跟另外一个对比大小？

var txt1="",txt2="";

fetch("第1个txt文件名")then(r=>rtext())then(t=>{

txt1=t;

fetch("第2个txt文件名")then(r=>rtext())then(t=>{

txt2=t;

//然后比较txt1和txt2的大小即可

});

});

读取某个文件夹下的所有文件

/

public static boolean readfile(String filepath) throws FileNotFoundException, IOException {

try {

File file = new File(filepath);

if (!fileisDirectory()) {

Systemoutprintln("文件");

Systemoutprintln("path=" + filegetPath());

Systemoutprintln("absolutepath=" + filegetAbsolutePath());

Systemoutprintln("name=" + filegetName());

} else if (fileisDirectory()) {

Systemoutprintln("文件夹");

String[] filelist = filelist();

for (int i = 0; i < filelistlength; i++) {

File readfile = new File(filepath + "\\" + filelist[i]);

if (!readfileisDirectory()) {

Systemoutprintln("path=" + readfilegetPath());

Systemoutprintln("absolutepath="

+ readfilegetAbsolutePath());

Systemoutprintln("name=" + readfilegetName());

} else if (readfileisDirectory()) {

readfile(filepath + "\\" + filelist[i]);

}

}

}

} catch (FileNotFoundException e) {

Systemoutprintln("readfile() Exception:" + egetMessage());

}

return true;

}
