我这样实现当点删除按钮时候,出来提示:确实删除吗?按确定,删除,按否,返回>?? 可是不行，不知道怎么搞

<a href="user_del.asp?id=<%=rs("id")%>" target="iframe1" onclick="javaScript:return confirm('您确定删除此用户？！')">删除</a>
楼主试试这种办法，user_del.asp是执行删除的页，记得要在页面建一个iframe1

建iframe1做什么
另外我做的是JSP页面
也可以么？
把代码贴出来看看，不然没有办法分析!!
只能怀疑定位没有正确执行!
加上两个alert,再分析执行结果!
是不是都执行，还是执行一个??
if(confirm("确实要删除吗"))
{
  window.location="deleteCompetition.jsp?id=" + compId;//------怀疑这里定位有问题
  alert("yes"):
   return true;

}
else
{
alert("no");
return false;

}
还有我是按button进行判断的啊

这句里面把type="submit" 改成 type = "button"就行了
