提示框问题

[wjcking]

<asp:button id=l1 runat=server onclick=t1/>
l1.Attributes.Add("onClick","confirm('确定吗?')");

void t1(obj s,Evt e)
{
}
怎么才能可判断值是true,还是false,如果是true打印1,另外打印2 这段语句该怎么写？

[wacle]

l1.Attributes["onclick"]="javascript:return confirm('are you sure?');";

<asp:button id=l1 runat=server onclick=t1/>
l1.Attributes.Add("onClick","javascript:return confirm('确定吗?')");

<script language=javascript>
<!--
function t1()
{
window.print();
}
//-->
</script>

[chnking]

<asp:button id=l1 runat=server onclick=t1/>
l1.Attributes.Add("onClick","javascript:return confirm('确定吗?')");

<script language=javascript>
<!--
function t1()
{
window.print();
}
//-->
</script>

public void Page_Load(object sender,EventArgs e)
{
btnDel.Attributes.Add("onclick","confirm('确定吗?')");
}

public void MsgDel_Click(object sender,EventArgs e)
{
string strCon=Application["db_app"].ToString();
string strSQL="Delete from db_gb where ID="+Request.QueryString["id"];
OleDbConnection objCon=new OleDbConnection(strCon);
OleDbCommand objCmd=new OleDbCommand(strSQL,objCon);
objCon.Open();
objCmd.ExecuteNonQuery();
objCon.Close();

<asp:button id=btnDel runat=server />
//＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
点了取消以后，还是删除记录

[fly_miss]

btnDel.Attributes.Add("onclick","return confirm('确定吗?')");

[lbyang]

使btnDel的验证属性改成fase;
