javascript - 无法访问 JS 对象中的值

Question

我想学习更多面向对象的 JavaScript。我创建了类似的东西:

    var Player = {
        player: $('#player'),
        video: Player.player
    };

    console.log(Player.video);

console.log 返回 Uncaught TypeError: Cannot read property 'player' of undefined。我的错误在哪里？

Answer 1

您不能在初始化时引用对象。找到解释和建议的解决方案 here !

表明你可能想要这样的东西:

var Player = new function() {
    this.player = $('#player');
    this.video = this.player;
}; 

console.log(Player.player);
