嘿我想在jquery中获取我的下拉列表的值或选定索引 . 当我尝试这个时，它会以未定义的形式返回 . 当我尝试.index（）时，它只给我索引而不是选中的索引 .
<td>
<asp:DropDownList id="ddlFullName" runat="server" Width="48px" />
</td>
这是我的Jquery .
$(document).ready(function () {
$("select[id$='_ddlFullName']").change(function () {
console.log("changed");
var selectedText = $("select[id$='_dllFullName'] option:selected").val();
console.log("selected text= " + selectedText);
});
});
另一件事 . 我正在使用DotNetNuke，所以在客户端它将我的下拉列表包装成一个链接，其中包含选定的值或 Span 中显示的文本，如下所示 .
<a href="javascript:void(0)" id="Skinneddnn_ctr481_ViewResellerSite_Dashboard_ResellerSite/BulkMailingProcessingMain_ddlFullName" unselectable="on" tabindex="-1" class="rfdSelect rfdSelect_Growll" style="width: 44px;"><span class="rfdSelectOuter"><span class="rfdSelectText">c_county</span></span></a>
使用下面的实际下拉列表
<select name="dnn$ctr481$ViewResellerSite$Dashboard$ResellerSite/BulkMailingProcessingMain$ddlFullName" id="dnn_ctr481_ViewResellerSite_Dashboard_ResellerSite/BulkMailingProcessingMain_ddlFullName" style="width: 44px;" class="rfdRealInput" _rfddecoratedid="Skinneddnn_ctr481_ViewResellerSite_Dashboard_ResellerSite/BulkMailingProcessingMain_ddlFullName">
