Question

如何在删除记录前显示确认消息框？按钮应仅为YES或NO。不是OK或CANCEL。我有这个代码，但它只适用于c＃winforms ...

if (MessageBox.Show("Delete record no. " + numID.Text + "?", "Confirm User Delete", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
    //codes to delete records
}

如果您正在显示此客户端，那么您应该使用Javascript。一个好方法是使用jQuery dialog方法。例如：

标记：

<div id="dialog-confirm">This is the content</div>

使用Javascript：

 $( "#dialog-confirm" ).dialog({
      resizable: false,
      height:280,
      modal: true,
      buttons: {
        "Yes": function() {
          $( this ).dialog( "close" );
        },
        "No": function() {
          $( this ).dialog( "close" );
        }
      }
 });
