用JS确认删除的两种函数

<script language="javascript">
    function delID(ID,url,mes){
        var mymes;
        mymes=confirm(mes);
        if(mymes==true){
            window.location=url+ID;
        }
    }
</script>

调用方法
<a href=# onclick="delID(1,'delete.asp?id=','确实要删除吗?')">test</a>

<script language="javascript">
function delcfm()
{
    if(!confirm("确认要删除？"))
    {
        window.event.returnValue = false;
    }
}
</script>

调用方法
<a href="delete.php?id=1" onclick="delcfm()">test</a>
