javascript - 将数组转换为对象javascript

Question

我有以下数组:

["recordList", "userList", "lastChanged"]

我想要这样的东西:

lastChangedValue = "231231443234";        

var object = {};

object = {
   recordList: {
       userList: {
         lastChanged: lastChangedValue 
      }
   }
}

我该怎么做？提前致谢。

Answer 1

试试这个:

var array = ["recordList", "userList", "lastChanged"];


var value = "231231443234";        

function arrayToObject(array, object, value) {
  var ref = object;
  for (var i=0; i<array.length-1; ++i) {
    if (!ref[array[i]]) {
        ref[array[i]] = {};
    }
    ref = ref[array[i]]
  }
  ref[array[array.length-1]] = value;
  return object;
}
alert(JSON.stringify(arrayToObject(array, {}, value)));
