How I can make my drop down disable in Edit but enable in Create User. I have the drop down in MVC view and Create and Edit user in jquery. I already tried these but not making it disabled using any of these in jquery:

 $("#dropdown").prop("disabled", false);  

 $('#dropDownId').attr('disabled', true);

 $('#dropdown').prop('disabled', true);

and in my MVC with when I have like this:

  <select id="organization" class="create-user-select-half" disabled>

it making it disabled but I can not again Enable it in jquery.


You have to set

$("#dropdown").prop('disabled', true);

for disabling a control. To enable it again you have to call:

$("#dropdown").prop('disabled', false);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="organization" class="create-user-select-half" disabled>
  <option value="1">dsdsd</option>

<button onclick="$('#organization').prop('disabled', false)">Enable</button>
<button onclick="$('#organization').prop('disabled',true)">Disable</button>
