如何在本地存储中保存游戏分数

Question

我想在本地存储中保存游戏分数。我试过了

localStorage.setItem("score", myScore);

和

var score = localStorage.getItem(myScore);

想保存游戏比分但是没用。我做错了吗？我该怎么办？

function updateGameArea() {
        var x, height, gap, minHeight, maxHeight, minGap, maxGap;
        for (i = 0; i < myObstacles.length; i += 1) {
            if (myGamePiece.crashWith(myObstacles[i])) {
                return;
            } 
        }
        myGameArea.clear();
        myGameArea.frameNo += 1;
        if (myGameArea.frameNo == 1 || everyinterval(150)) {
            x = myGameArea.canvas.width;
            minHeight = 20;
            maxHeight = 200;
            height = Math.floor(Math.random()*(maxHeight-minHeight+1)+minHeight);
            minGap = 50;
            maxGap = 200;
            gap = Math.floor(Math.random()*(maxGap-minGap+1)+minGap);
            myObstacles.push(new component(10, height, "green", x, 0));
            myObstacles.push(new component(10, x - height - gap, "green", x, height + gap));
        }
        for (i = 0; i < myObstacles.length; i += 1) {
            myObstacles[i].x += -1;
            myObstacles[i].update();
        }
        myScore.text="SCORE: " + myGameArea.frameNo;
        myScore.update();
        myGamePiece.newPos();
        myGamePiece.update();
    }
    
    localStorage.setItem("score", myScore);
    var score = localStorage.getItem(myScore);

Answer 1

关键是"score"不是myScore

localStorage.setItem("score", myScore);
let score = localStorage.getItem("score"); // <--- key is "score", not myScore
