javascript - 如何在循环时返回数组中的最大数

Question

如何在循环时进行类型检查并返回数组的最大数字？我无法让下面的代码工作。

var v = prompt("Enter a Value", "0");
var w = prompt("Enter a Value", "0");
var x = prompt("Enter a Value", "0");
var y = prompt("Enter a Value", "0");
var z = prompt("Enter a Value", "0");
var num1 = parseInt(v, 10);
var num2 = parseInt(w, 10);
var num3 = parseInt(x, 10);
var num4 = parseInt(y, 10);
var num5 = parseInt(z, 10);

var numArray = [num1, num2, num3, num4, num5];
var highest = 0;
for (var i = 0; i <= numArray.length; i++) {
    if (numArray[i] > highest) {
        highest = numArray[i];
    }
}

return(highest);

您可以简单地执行以下操作:

var highest = Math.max.apply(null, numArray);
