Question

我有一个对象数组，我想在该数组中选择某个对象的属性。当我尝试以下代码时，它不起作用，我在字符串中没有得到任何值：

var _string = teams[2].name;

在数组代码下面：

var teams = new Array (team1, team 2, team3);

var team1 = {
     name: "team 1",
     matches: 5 
}


var team2 = {
     name: "team 2",
     matches: 4 
}


var team3 = {
     name: "team 3",
     matches: 3 
}

一些帮助会很棒： - ）

Answer 1

你应该首先宣布你的团队和你的阵列如下：

var team1 = {
     name: "team 1",
     matches: 5 
}

var team2 = {
     name: "team 2",
     matches: 4 
}

var team3 = {
     name: "team 3",
     matches: 3 
}

var teams = [team1, team2, team3];

另请注意，代码中team和2之间的空格不正确。

Answer 2

错误var teams = new Array (team1, team 2, team3);，应为var teams = new Array (team1, team2, team3);

您在team和2之间添加了不必要的空格：）
