javascript - 我可以将这个循环数组转换为 Json 对象吗？

Question

我有这个数组。

[["20152","15301","020053","2016-08-05","05:00","06:00","07150100190"],["20152","15301","020051","2016-08-05","03:00","04:00","07150100190"],["20152","15301","000040","2016-08-05","01:00","02:00","07150100190"],["20152","15301","020050","2016-08-05","07:00","08:00","07150100190"]]

可以改成

var timetable = [{
    "thakad"  : "20152", 
    "prodi"   : "15301",
    "mk"      : "020053",        
    "date"    : "2016-08-05", 
    "open"    : "05:00",
    "close"   : "06:00",
    "number"  : "07150100190"
},
{
    //and keep looping dynamically
}];

如果可以，我如何在 JavaScript 中循环更改数组？

Answer 1

您可以结合使用array.map和array.reduce

var array = [["20152","15301","020053","2016-08-05","05:00","06:00","07150100190"],["20152","15301","020051","2016-08-05","03:00","04:00","07150100190"],["20152","15301","000040","2016-08-05","01:00","02:00","07150100190"],["20152","15301","020050","2016-08-05","07:00","08:00","07150100190"]]
var keys = ["thakad","prodi","mk","date","open","close","number"]

var r = array.map(function(el){
  return keys.reduce(function(c,n,i){
    c[n] = el[i]
    return c;
  },{});
});

console.log(r)
