回发确认按钮的OnClientClick ASP.NET
问题描述：
<asp:Button runat="server" ID="btnUserDelete" Text="Delete" CssClass="GreenLightButton"
OnClick="BtnUserDelete_Click"
OnClientClick="return UserDeleteConfirmation();"
meta:resourcekey="BtnUserDeleteResource1" />
我曾尝试：
function UserDeleteConfirmation() {
if (confirm("Are you sure you want to delete this user?"))
return true;
else
return false;
}
和
function UserDeleteConfirmation() {
if (confirm("Are you sure you want to delete this user?")) {
__doPostBack(btnUserDelete, '');
}
return false;
}
和他们没有工作。
答
试试这个：
<asp:Button runat="server" ID="btnUserDelete" Text="Delete" CssClass="GreenLightButton"
OnClick="BtnUserDelete_Click"
OnClientClick="if ( ! UserDeleteConfirmation()) return false;"
meta:resourcekey="BtnUserDeleteResource1" />
此方式，当用户点击取消，他点击时没有返回时，才执行OK。
This way the "return" is only executed when the user clicks "cancel" and not when he clicks "ok".
顺便说一句，可以缩短UserDeleteConfirmation功能：
By the way, you can shorten the UserDeleteConfirmation function to:
function UserDeleteConfirmation() {
return confirm("Are you sure you want to delete this user?");
}
