将数组转换为json对象

Question

I have an array in java script .. something like: var myarray = ['a','b',c']; and var item = 'Name'; and I want to convert that to something like

{
 a:{
    b:{
       c:{
          item:'Name'     
         }
      }
   }
}

Answer 1

var result = myarray.reverse().reduce(function (value, key) {
    var result = {};
    result[key] = value;
    return result;
}, { item : item });

In other words, you're packing the result layer by layer into new objects, using your keys from the array.

Answer 2

var obj = {};
var curobj = obj;
for (var i = 0; i < myarray.length; i++) {
    var newObj = {};
    newObj[myarray[i]] = newObj;
    curObj = newObj;
}
curObj.item = item;

The result you want will be in the obj object.
