ASP.NET 弹出消息确认框_aspnet确认弹窗-优快云博客

这篇文章展示了如何在ASP.NET中实现一个功能，当用户点击按钮时，会弹出一个JavaScript确认框。如果用户确认操作，后台代码将接收到‘true’并执行相应操作，否则显示‘false’。关键在于利用隐藏的按钮和HiddenField来传递确认结果。

点击弹出弹出消息确认框，并根据返回结果做相应的操作

后台代码

        /// <summary>
        /// 点击触发确认框的按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Button1_Click(object sender, EventArgs e)
        {
            string msg = "确认操作?";
            string script = $"document.getElementById('{HiddenField1.ClientID}').value=confirm('{msg}');document.getElementById('{Button2.ClientID}').click();";
            ClientScript.RegisterStartupScript(GetType(), "confirm", script, true);
        }
        /// <summary>
        /// 判断事件返回结果
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Button2_Click(object sender, EventArgs e)
        {
            if(HiddenField1.Value == "true")
            {
                Label.Text = "true";
            }
            else
            {
                Label.Text = "false";
            }
        }

前端代码

<div>
    <asp:Button ID="Button1" runat="server" Text="Button"  OnClick="Button1_Click"/>
    <asp:Label ID="Label" runat="server" Text=""></asp:Label>
    <!-- 被隐藏的按钮 -->
    <div style="display:none">
        <asp:Button ID="Button2" runat="server"  OnClick="Button2_Click" />
    </div>
    <asp:HiddenField ID="HiddenField1" runat="server" />
</div>
