解决方法：
前台：<table width="100%">
                <tr>
                    <td align="left" style=" border:0px;"><asp:TextBox ID="txtShipmentsUnit" Width="100%" runat="server" MaxLength="50"></asp:TextBox></td>
                    <td align="left" style=" border:0px;"><ajaxToolkit:AutoCompleteExtender ID="autoShipmentsUnit" runat="server" ServiceMethod="GetLogisticsUnitList"
                        ServicePath="/WebService/GetLogisticsUnit.asmx" MinimumPrefixLength="1" FirstRowSelected="true" Enabled="true" EnableCaching="false"
                        CompletionSetCount="10" TargetControlID="txtShipmentsUnit" CompletionInterval="100" UseContextKey="true" OnClientItemSelected="OnACEItemSelected">
                    </ajaxToolkit:AutoCompleteExtender></td>
                    <td align="left" style=" border:0px;"><input id="AutoComplete_Hidden" type="hidden" runat="server" /></td>
</tr></table>JSfunction OnACEItemSelected(source, eventArgs) {
//            document.getElementById("AutoComplete_Hidden").value = eventArgs.get_value();
            alert("Value值：" + eventArgs.get_value() + "\nText值：" + eventArgs.get_text());
        }
