Javascript Battleship游戏

Question

我用javascript做了一个简单的战舰游戏，但是没有正确的workimg。我将位置放在数组中，并尝试使用splice方法从该数组中删除猜测的位置。但是它会警告“ MISS！”当我输入0到6之间的任何数字时。

编辑：我通过使用parseInt方法进行提示来解决了这个问题。

var location1 = Math.floor(Math.random() * 5);
var location2 = location1 + 1;
var location3 = location2 + 1;

var locations = [];
locations.push([location1, location2, location3]);

var guess;
var hits = 0;
var guesses = 0;

var isSunk = false;

while (isSunk == false) {
    guess = prompt("Enter your guess(0 - 6)");
    if (guess < 0 || guess > 6) {
        alert("Please enter a valid number!");
    } else {
        guesses++;

        if (locations.indexOf(guess) > 0) {
            locations.splice(locations.indexOf(guess), 1);
            hits++;
            alert("HIT!");
            if (hits == 3) {
                isSunk = true;
                alert("You sank my battleship!");
            }
        } else {
            alert("MISS!");
        }
    }
}

var stats = "You took " + guesses + " guesses to sink the battleship, which 
means your shooting accuracy was " + (3 / guesses);
alert(stats);

做一件事创建具有类似元素的数组

var location=[1,2,3,4,5]

，而不是从中删除数组delete元素的索引
