Dear Friends,

I am getting the data by calling the web method via Jquery and need to bind the data to dropdownlist box.

But I cant bind the same. The code I have used is below.

JavaScript

var dropdown = $("#ddl_req_by");

   var json = msg.d;
   $.each($.parseJSON(json), function () {
   alert(this.REQ_BY);
  $("#ddl_req_by").append($("<option></option>").val(this.REQ_BY).html(this.REQ_BY));
                                    
});

Please can one guide me on this.

Could you show relevant part of HTML? At least the elements with id="dropdownbox1" and id="ddl_req_by". (Do you even have elements with those two attributes, exactly?)

You can follow the below mentioned example and adjust it according to your situation.

View

XML

<select id="purchasedPackages" name="purchasedPackages">
                    </select>

JavaScript

<script type="text/javascript">
  Sys.require('jQuery', function () {
     
                    $.ajax({
                        url: "/Portal/GetPurchasedPackages",
                        dataType: 'json',
                        data: { },
                        success: function (data) {
                            $("#purchasedPackages").fillSelect(data);
                        }
                    });

                    $.fn.fillSelect = function (data) {
                        return this.clearSelect().each(function () {
                            if (this.tagName == 'SELECT') {
                                var dropdownList = this;
                                $.each(data, function (index, optionData) {
                                    var option = new Option(optionData.Text, optionData.Value);
                                    if ($.browser.msie) {
                                        dropdownList.add(option);
                                    } else {
                                        dropdownList.add(option, null);
                                    }
                                });
                            }
                        });
                    };

                    $.fn.clearSelect = function () {
                        return this.each(function () {
                            if (this.tagName == 'SELECT')
                                this.options.length = 0;
                        });
                    };
</script>
});

I hope this will help to you.
