javascript - 将数组中的数组变成对象

Question

最佳转换方式

a = [['tokyo', '10', '20'],['newyork', '30', '40'],['singapore', '50', '60']];

至

a = [{city:'tokyo', lat:'10', lon:'20'},{city:'newyork', lat:'30', lon:'40'},{city:'singapore', lat:'50', lon:'60'}];

谢谢!

您可以使用#map()函数将其转换为对象数组 - 请参阅下面的演示:

var a = [['tokyo', '10', '20'],['newyork', '30', '40'],['singapore', '50', '60']];

var result = a.map(function(e) {
  return {
    city: e[0],
    lat: e[1],
    lon: e[2]
  }
},[]);

console.log(result);

.as-console-wrapper{top:0;max-height:100%!important;}
