javascript中的多个if语句

Question

我有原因：

if(
                (attackX > enemies[enemy].posX && attackX < enemies[enemy].posX + enemies[enemy].width) || (attackX + 32 > enemies[enemy].posX && attackX + 32 < enemies[enemy].posX + enemies[enemy].width)
                &&
                (attackY > enemies[enemy].posY && attackY < enemies[enemy].posY + enemies[enemy].height) || (attackY + 32 > enemies[enemy].posY && attackY + 32 < enemies[enemy].posY + enemies[enemy].height)
            ){ //CODE }

console.log(attackX > enemies[enemy].posX && attackX < enemies[enemy].posX + enemies[enemy].width); //true
        console.log(attackX + 32 > enemies[enemy].posX && attackX + 32 < enemies[enemy].posX + enemies[enemy].width); //false
        console.log(attackY > enemies[enemy].posY && attackY < enemies[enemy].posY + enemies[enemy].height); //false
        console.log(attackY + 32 > enemies[enemy].posY && attackY + 32 < enemies[enemy].posY + enemies[enemy].height); //false

在那种情况下工作，但我不知道为什么（有AND操作员）

查看operator precendence

＆amp;＆amp;具有更高的优先权，从而首先评估 - ＆gt;你得到 true || (false && false) || false会产生true。要解决此问题，请将||语句组放在括号中。
