How to turn array into object?

Question

I have an array which I would like to turn into an object with one twist. I would like to set each key and value of the object to be the value of the index of the array which I am currently on.

$('#MoveRight').click(function () {
        var selectedUsers = $('#allUsersDD').val();
        //turn to object
    });

selectedUsers is an array

@PM77-1 Yeah, I know. But how would you have phrased the title? — Andrew Kilburn, Dec 10 '15 at 16:16

you can do it with a single loop.

var usersObj = {};
for (var k = 0; k < selectedUsers.length; k++) {
    usersObj[k] = selectedUsers[k];
}

This also set the key to be the 1,2 and so forth. However I have changed my code so it doesn't matter – Andrew Kilburn Dec 10 '15 at 16:55

If you have a js Array of lots of key-value pairs, you can convert it like this:

var array = [{key:"one",value:1},{key:"two",value:2},....]

var newObject = {}

for(var i = 0; i < array.length; i++){
    newObject[array[i].key] = array[i].value;
}

$('#MoveRight').click(function () {
  var selectedUsers = $('#allUsersDD').val();
  var obj = {};
    $(selectedUsers).each(function (i, v) {
      var key = '_' + i;
      obj.key = v;
  });
});

This also sets each key of the object to be the index of the array. In my question I asked for the key and value of the object to be the value of the array which i loop through – Andrew Kilburn Dec 10 '15 at 16:25
