Question

我有两个数组，其中一个数据

var elements = [["1","a",1],["2","b",2],["3","c",3],["4","d",4],["5","e",5]];

另一个包含我想使用上述数据创建的对象名称。

var names =["a1","a2","a3","a4","a5"];

这是原型类

var Video = function(title,uploader,seconds){
this.title = title;
this.uploader = uploader;
this.seconds = seconds;
}

我希望得到：

a1将具有值：title：＆＃34; 1＆＃34;，uploader：＆＃34; a＆＃34;，seconds：1

带有值的

a2：标题：＆＃34; 2＆＃34;，上传者：＆＃34; b＆＃34;，秒：2

与休息相同。

或者可能还有其他方法可以完成下面的任务吗？

使用数据数组和for循环实例化5个视频对象。

Answer 1

function Video(title, uploader, seconds) {
    this.title = title;
    this.uploader = uploader;
    this.seconds = seconds;
}

var elements = [["1","a",1],["2","b",2],["3","c",3],["4","d",4],["5","e",5]];

var names =["a1","a2","a3","a4","a5"];

// create instances
var videos = elements.map(data => new Video(...data));

// add them to hashmap
var result = names.reduce((acc, current, index) => {
    acc[current] = videos[index];
    return acc;
  }, {});

console.log(result);

如何使用数组和for循环来实例化对象？
