如何根据弹出的对话框返回的确定/取消的值来执行下一步的代码呢？

 1<script language="javascript">   
 2function submitformdelete()   
 3{   
 4var ok;   
 5ok= window.confirm("确定要删除" + document.form1.NumberID.value + "记录吗？" )   
 6if (ok)   
 7{   
 8form1.ActionName.value="Delete"   
 9form1.action="ConfirmAddGZZD.asp";   
10form1.submit();   
11}   
12}   
13</script>

 1<script language="VBScript">   
 2Sub YesOrNo()   
 3Dim yesno   
 4yesno=MsgBox("确实要删除吗？",vbYesNo,"删除提示")   
 5Select Case yesno   
 6Case 6   
 7Window.navigate("del.asp")   
 8Case 7   
 9history.back()   
10end Select   
11End Sub   
12</script>

1<input name="b1" onclick="YesOrNo()" type="button" value="删除"/>

 1<form action="submit.asp" onsubmit="return confirm('确认删除吗？')">

 4var truthBeTold = window.confirm("单击“确定”继续。单击“取消”停止。");

 6{   
 7window.alert("欢迎访问我们的 Web 页！");
