我想知道如何在两个 bool(boolean) 变量之间切换。这在第一次运行代码时可以正常运行,但是在第二次运行之后,输出将不正确。
输出第一次运行switchPlayer():
player1.isActive = false,
player2.isActive = true
输出第二次运行switchPlayer():
player1.isActive = true,
player2.isActive = true
以下是我编写的代码:
var Player = function(score, isActive){
this.score = score;
this.isActive = isActive;
}
Player.prototype.toggleIsActive = function(){
if(this.isActive === false){
this.isActive = true;
} else{
this.isActive = false;
}
}
function switchPlayer(){
if(player1.isActive === true){
player1.toggleIsActive();
player2.toggleIsActive();
} else{
player1.isActive = true;
}
}
var player1 = new Player("0", true);
var player2 = new Player("0", false);
switchPlayer();
switchPlayer();
最佳答案
您可以像这样简化它:
Player.prototype.toggleIsActive = function(){
this.isActive = !this.isActive;
}
function switchPlayer(){
player1.toggleIsActive();
player2.toggleIsActive();
}
ToggleIsActive应该与以前相反。还要注意,switchPlayer仅调用没有特定逻辑的切换。
