我关注了几个网络资源来了解如何从客户端显示弹出窗口,并编写了以下代码:
<asp:ImageButton runat="server" ID="btnOk" ImageUrl="imagens/btnAlterar.gif" OnClientClick="btnOkClick()" />
<asp:LinkButton runat="server" ID="dummyForPopup" Visible="false"/>
<ajaxToolKit:ModalPopupExtender runat="server" BehaviorID="btnOkPopupBehavior" ID="MPXtender" TargetControlID="dummyForPopup" PopupControlID="pnlUpdateUserModal" BackgroundCssClass="modalBackground" OkControlID="btnCloseRequestUserUpdate" OnOkScript="userUpdReq_onOk()" />
function btnOkClick()
{
if(validateAll())
{
var behavior = $find('btnOkPopupBehavior');
if (behavior)
{
behavior.show();
}
else
{
var lblOutput = $get('<%= lblOutput .ClientID %>');
lblOutput .innerText = 'Couldn't find popup';
}
}
}
以前我将模态弹出窗口链接到确定按钮,它工作得很好。现在我需要在打开弹出窗口之前进行一些验证,并且此代码不再起作用 =/
