Javascript:从数组中的对象中选择属性

Question

我有一个对象数组，我想选择该数组中某个对象的属性。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;

数组代码如下:

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:-)

谢谢

Answer 1

您应该首先声明您的团队，然后声明您的数组，如下所示:

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，代码中的 team 和 2 之间有一个空格，这是不正确的。
