如何显示消息框并从aspx.cs获得确认YES或NO

Question

我需要显示一个消息框,用于确认是否删除项目但不确定如果我使用javascript警报该怎么做,而不是如何获得确认？

Answer 1

你可以使用这个confirm功能:

if (confirm('Are you sure you want to delete this item?')) {
    // TODO : the user confirmed
}

正如您使用ASP.NET标记了您的问题:

<asp:LinkButton 
    ID="DeleteButton" 
    runat="server"
    CommandName="Delete" 
    Text="Delete"
    OnClientClick="return confirm('Are you sure you want to delete this item?');" 
/>
