javascript - 如何在数组 javascript 中添加带有 id 的新 key ？

Question

我尝试这样:

<script type="text/javascript">
    var club = [
        {id:123, name:'chelsea'},
        {id:456, name:'mu'},
        {id:789, name:'liverpool'}
    ];

    var newClub = club.map(function(element){
       element.original = true;
       element.kw = false;
       return element;
    });

    console.log(newClub);
</script>

它有效。但我想要 key 原件和带有 id 的 kw，如下所示:

var club = [
    {id:123, name:'chelsea', original123:true, kw123:false},
    {id:456, name:'mu', original456:true, kw456:false},
    {id:789, name:'liverpool', original789:true, kw789:false}
];

我该怎么做？

您应该使用动态属性:

var newClub = club.map(function(element) {
  element['original' + element.id] = true;
  element['kw' + element.id] = false;
  return element;
});
