HEllo Team,
I have a input as follows:

<pre lang="xml">&lt;td&gt;
                        &lt;select id=&quot;allocateToSelect&quot; class=&quot;combo150&quot;&gt;
                             &lt;/select&gt;
                    &lt;/td&gt;
I am inserting the DropDown option value as follows:
<pre>function GetDisplayQCID() {
            debugger;
            $.ajax({
                url: 'QCAllocation.aspx/GetDisplayQCID',
                type: 'POST',
                contentType: 'application/json; charset=utf-8',
                dataType: "json",
                success: function (result) {
                    debugger;
                    if (result.d != '') {
                        if (result.d != '' &amp;&amp; result.d != null) {
                            DisplayQCIDList = JSON.parse(result.d);
                            var drawRow = function (qcIDs) {
                                /*var dropdownQC = document.getElementById('qcSelect');*/ //for append to another DropDown.
                                var dropdownQC = document.getElementById('allocateToSelect');

                                /*var dropdownAllocateToQC = document.getElementById('allocateToSelect');
                                dropdownAllocateToQC.innerHTML = dropdownAllocateToQC.innerHTML + dropdownQC.innerHTML;*/

                                var opt = document.createElement('option');
                                opt.innerHTML = '';
                                dropdownQC.appendChild(opt);

                                for (var i = 0; i &lt; qcIDs.length; i++) {
                                    opt = document.createElement('option');
                                    opt.value = qcIDs[i].Id; // it will give the ID through which we can find the value which present in DropDown.
                                    opt.innerHTML = qcIDs[i].NetworkId;
                                    dropdownQC.appendChild(opt);
                                }
                            }

                            drawRow(DisplayQCIDList);
                            /*$('#qcSelect option').clone().appendTo('#allocateToSelect');*/ //for append to another DropDown.
                            manageOverlay(false);
                        }
                    }

                },
                error: function (error) {
                    manageOverlay(false);
                    alert(error.responseText);
                },
                async: false
            })
        };

I have the Function in Jquery as follows:

<pre lang="cs">$('#allocateToSelect').change(function () {
    debugger;
    $("#allocateToSelect option:selected").val();
    GetQCCount();
});&amp;lt;/pre&amp;gt;&lt;/pre&gt;</pre>
