在本地存储中设置变量
问题描述：
目前正在设计游戏并且想法是高分，因此当当前分数超过本地分数时，它将被替换：
Currently designing a game and the idea is that of a high score, so that when the current score is more than the local storage one it is replaced:
localStorage.setItem('highScore', highScore);
var HighScore = localStorage.getItem('highScore');
if (HighScore == null || HighScore == "null") {
HighScore = 0;
}
if (user.points > HighScore) {
highScore = parseInt(HighScore);
}
return highScore
谢谢你们
答
这应该指向正确的方向。
This should point you in the correct direction.
// Get Item from LocalStorage or highScore === 0
var highScore = localStorage.getItem('highScore') || 0;
// If the user has more points than the currently stored high score then
if (user.points > highScore) {
// Set the high score to the users' current points
highScore = parseInt(user.points);
// Store the high score
localStorage.setItem('highScore', highScore);
}
// Return the high score
return highScore;
