读取文件并检查它是否在循环节点javascript syncronous的末尾

^我想这样做，它一直运行到文件结束。有什么想法吗？

我猜您希望逐行遍历返回的缓冲区

var fs = require("fs");
var text = fs.readFileSync("./mytext.txt").toString('utf-8');
var textByLine = text.split("\n")


while(!text.atEnd())

有一个很酷的软件包，我以前在github中使用过。希望它在这里也能为你工作。看看这里

fs.readFileSync，读取整个文件。所以没有什么需要等待的了。这很好，谢谢，但是我如何分割行，例如var splitLine=liner.split（'，'）；所以我可以检索行的索引并将其存储到对象中？

var fs = require("fs");
var text = fs.readFileSync("./mytext.txt").toString('utf-8');
var buffer = text.split("\n")

for (line in buffer) {
    // buffer[line] is your current line, do whatever you want with it here
}

var lineByLine = require('n-readlines');
var liner = new lineByLine('./mytext.txt');

var line;
var lineNumber = 0;
while (line = liner.next()) {
    console.log('Line ' + lineNumber);
    lineNumber++;
}

console.log('end of line reached');
