Jquery chosen set selected values from javascript

I am using jquery chosen and I want to set selected values from javascript

Javascript/Jquery

$(document).ready(function() {
  var selectedUserRole = document.getElementById('SelectedUserRole').value;
  var str_array = selectedUserRole.split(',');

  for (var i = 0; i < str_array.length; i++) {
    // Trim the excess whitespace.
    str_array[i] = str_array[i].replace(/^\s*/, "").replace(/\s*$/, "");
    // Add additional code here, such as:

    $("UserRole").prop('selectedValue', str_array[i]); // Here not working
  }
});

Html:

 @Html.DropDownList("UserRole", null, new { id = "UserRole", @class = "chosen-select", @multiple = "multiple", @placeholder = "Lütfen Rol Seçiniz", @style = "width: 250px;" })

str_array has values below

[5, 1, 7]

I want to set 5 value selected, 1 value selected 7 value selected

When I tried below 

$("UserRole").prop('selectedValue', str_array[i]);

it is not working for me.

As of now this way is supported to update multiple values:

$("#UserRole").val(str_array).trigger("chosen:updated");

You need to trigger the chosen:updated event after setting the select value

$("#UserRole").val(str_array[i]).trigger("chosen:updated");

To select multiple values

$(document).ready(function () {

    var selectedUserRole = document.getElementById('SelectedUserRole').value;

    var str_array = selectedUserRole.split(',');

    for (var i = 0; i < str_array.length; i++) {
        str_array[i] = str_array[i].replace(/^\s*/, "").replace(/\s*$/, "");
    }

    $("#UserRole").val(str_array).trigger("chosen:updated");
});

Use this

You missed '#'

$("#UserRole").prop('selectedValue', str_array[i]);

Instead of

$("UserRole").prop('selectedValue', str_array[i]);

It should be

$("#UserRole").prop('selectedValue', str_array[i]); // include '#' id selector here
