在JavaScript中从控制台读取输入时出错？

Question

我尝试过使用＆＃34; readline＆＃34;但我得到的错误如下：

你可以看到我只是想从控制台读取一个值。

solution.js：5

var input_stdin_array = "";

var input_currentline = 0;

function readLine（）{return input_stdin_array [input_currentline ++];}

function processData（input）{

var M = parseDouble(readLine());

console.log("M : "+M-1);

var T = parseInt(readLine());

var X = parseInt(readLine());

var final_price = M + ((T*12)/100) + ((X*12)/100);

console.log("The final price of the meal is $"+final_price);

}

process.stdin.resume（）;

process.stdin.setEncoding（＆＃34; ASCII＆＃34）;

_input =＆＃34;＆＃34 ;;

process.stdin.on（＆＃34; data＆＃34;，function（input）{

_input += input;

}）;

process.stdin.on（＆＃34; end＆＃34;，function（）{

过程数据（_Input）;

}）;

                 ^
