问题描述

HEllo团队，

我有如下输入：

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
            })
        };

我有Jquery中的函数如下：

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>

我在下拉列表中选择相同值时遇到问题。第一次接到电话在更改功能，但第二次，当我选择相同的值，它无法接听电话。请指导我。如何解决它请告诉我。

推荐答案

.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'）; * / //用于附加到另一个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 （'选项'）;
opt.value = qcIDs [i] .Id; //它将提供ID，通过该ID我们可以找到DropDown中存在的值。
opt.innerHTML = qcIDs [i] .NetworkId;
dropdownQC.appendChild（opt）;
}
}

drawRow（DisplayQCIDList）;
/ *

.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 != '' && 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 < 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'）; * / //用于附加到另一个DropDown。
manageOverlay（false）;
}
}

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

('#qcSelect option').clone().appendTo('#allocateToSelect');*/ //for append to another DropDown. manageOverlay(false); } } }, error: function (error) { manageOverlay(false); alert(error.responseText); }, async: false }) };

我有Jquery中的函数如下：

I have the Function in Jquery as follows:

<pre lang="cs">

（& amp; amp;＃39;＃allocateToSelect& amp; amp;＃39;）。change（function（）{
debugger;

('#allocateToSelect').change(function () { debugger;
