Question

我正在尝试将自动完成jQuery的当前值发送到ASP上的HiddenField

隐藏场：

 <asp:HiddenField ID="hidden" runat="server" />

当页面加载时我只将HiddenField值分配给某个TextBox：

Protected Sub PrepareSession(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim hid = hidden.Value
Requester_NumEmpleado_TB.Text = hid

是jQuery代码：

<script type="text/javascript">
     $("document").ready(function() {
         $("#Requester_NumEmpleado_TB").autocomplete({
             source: 'Search_VB.ashx',
             autoFocus: true,
             select: function(event, ui) {

             }
         });
         $("#<%=hidden.ClientID %>").val("20020177") //this works but i want to send the Autocomplete Value, not the "20020177"
     });
</script>

这适用于硬编码值，但我想从自动完成中发送值，而不是“20020177”。我该怎么做？

您需要做的就是检索select回调中自动填充字段中的值，并将其分配给隐藏字段的值：

<script type="text/javascript">
$("document").ready(function() {
    $("#Requester_NumEmpleado_TB").autocomplete({
        source: 'Search_VB.ashx',
        autoFocus: true,
        select: function(event, ui) {
            var autocomplete_value = $("#Requester_NumEmpleado_TB").val();
            $("#<%=hidden.ClientID %>").val(autocomplete_value);
        }
    });
});
</script>

从jQuery自动完成向HiddenField发送值
