为什么我的ModalPopupExtender不显示? ASP.NET& JavaScript的

标签: javascript vb.net function show modalpopupextender

我正在尝试从javascript调用模式弹出扩展程序。这是电话:

function MyFunction()
   {alert("test");
   $find('mdlPassword').show;}

我在调用时收到警报,但模态弹出扩展器不会显示。这是aspx的东西:

<!-- Popup Extenders Should Go Here -->
<asp:button id="Button1" runat="server" text="Button" style="display: none;" />
<asp:ModalPopupExtender ID="mdlPassword" runat="server"
    targetcontrolid="Button1" popupcontrolid="pnlPassword" 
    popupdraghandlecontrolid="PopupHeader" drag="true">
</asp:ModalPopupExtender>

<asp:Panel ID="pnlPassword" style="display: none" runat="server">
<div class="PasswordPopup">
            <div id="PopupHeader">&nbsp;</div>
            <div class="Controls">
                <center><table><tr>
                    <td>Please enter your password:</td><td><input type="password" name="Password" /></td></tr>
                <tr><td>&nbsp;</td>
                    <td><asp:linkbutton id="btnOK" runat="server" text="OK" />&nbsp;&nbsp;<asp:linkbutton id="btnCancel" runat="server" text="Cancel" /></td></tr></table></center>
            </div>
 </div>
</asp:Panel>

有什么想法吗?

谢谢,

尝试定义ModalPopupExtender的BehaviorID:

<asp:ModalPopupExtender ID="mdlPassword" runat="server"
    BehaviorID="mdlPassword"
    targetcontrolid="Button1" popupcontrolid="pnlPassword" 
    popupdraghandlecontrolid="PopupHeader" drag="true">
</asp:ModalPopupExtender>
  

BehaviorID :如果您想访问客户端   您可以设置客户端脚本代码中的扩展程序的行为   这个BehaviorID简化了流程。

显示和隐藏弹出窗口的脚本:

<script language="javascript">
   function showPopup()
   {
       $find('mdlPassword').show();
   }
   function hidePopup()
   {
       $find('mdlPassword').hide();
   }
</script>
