Hi all,
I really tired of searching solution for my problem.My problem is very simple.I want to set a value for dropdownlist using jquery ajax.But it doesnt works for me.I am using MVC.

What I have tried:

<select id="ddlRelationship" class="form-control chosen-select" name="ddlRelationship">
</select>

JQuery is:

$(document).ready(function () {
    
   
    refill()
   

});

function refill() {

    
    var id = $('#HdnOrganizationId').val()
   // alert(id);
  
      $.ajax({

        url: "/Organization/refill/" + id,
        type: "GET",
        contentType: "application/json;charset=utf-8",
        dataType: "json",

        success: function (result) {
            alert("Refill");
            alert(result.RelationshipId);
            relen();
             $('#TxtOrganization').val(result.RelationshipId);
             $('#ddlRelationship').val(result.RelationshipId);
           
        },
        error: function (errormessage) {
            alert(errormessage.responseText);
        }
    });
}

function relen() {
    $.getJSON("/Common/RelationshipList", function (data) {


        alert ('y56hyh')
        var temp = $('#ddlRelationship'); // cache it
        temp.empty();
        $("#ddlRelationship").append("<option value=''>Select an Option</option>");

        $.each(data, function (i, data) {      // bind the dropdown list using json result              
            $('<option>',
               {
                   value: data.RelationshipId,
                   text: data.Relationship
               }).html(data.Relationship).appendTo("#ddlRelationship");
        });
        $('#ddlRelationship').trigger("chosen:updated");
    })
}

Solution 1

refill() and relen() both are async calls. You're trying to set the values in your first call. Hence,

$('#TxtOrganization').val(result.RelationshipId);
$('#ddlRelationship').val(result.RelationshipId);

Write this code in your relen() success, after data is bound to dropdown.
Pass result.RelationshipId as a parameter to relen().
