回发确认按钮的OnClientClick ASP.NET [英] Confirm postback OnClientClick button 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。

推荐答案

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?");
}
