Javascript "variable“未定义
Javascript "variable“未定义

我已经写了一个脚本，它从用户那里获取不同单位的分数，然后将它们添加到一个数组中，显示分数和平均值。
当我运行脚本时，它运行得很好，但它显示的不是平均值，而是'grade‘is not。
var subjects = ["CF:", "DaD:", "PoP:", "N&CS:", "SAD:", "APP:"];
var grades = ["", "", "", "", "", ""];
var result;
grades[0] = prompt("Please enter your marks for CF: ");
grades[1] = prompt("Please enter your marks for DaD: ");
grades[2] = prompt("Please enter your marks for PoP: ");
grades[3] = prompt("Please enter your marks for N&CS: ");
grades[4] = prompt("Please enter your marks for SAD: ");
grades[5] = prompt("Please enter your marks for APP: ");
console.log("Units and grades are: ");
console.log(subjects[0] +"\t"+ grades[0] );
console.log(subjects[1] +"\t"+ grades[1] );
console.log(subjects[2] +"\t"+ grades[2] );
console.log(subjects[3] +"\t"+ grades[3] );
console.log(subjects[4] +"\t"+ grades[4] );
console.log(subjects[5] +"\t"+ grades[5] );
result = grades[0] + grades[1] + grades[2] + grades[3] + grades[4] +
grade[5];
console.log("Average: " + "\t" + result / 6);有谁有什么想法吗？对于糟糕的javascript，我很抱歉，我对此还是个新手。

在这段代码中，
result = grades[0] + grades[1] + grades[2] + grades[3] + grades[4] + grade[5];grade5必须是等级%s5。您错过了“%s”点。
