.net的问题,直接上代码了
//1 . Response.Write("<script>document.getElementById('adds').style.display = 'block';</script>");

  //2. ScriptManager.RegisterStartupScript(this, this.GetType(), "", "document.getElementById('adds').style.display = 'block';location='SideDish.aspx'", true);

1和2要输入的js怎么都执行不了啊,目的让页面的一个层显示,它默认的是隐藏的,坐等了,先谢谢大家

------解决方案--------------------
首先确定document.getElementById('adds'是否为空

前台写个js 用alert弹出看看
------解决方案--------------------
可以是js脚本生成的位置靠前,执行js语句时还没出现这个adds的div。
------解决方案--------------------
第一种是太靠前,页面DOM还没加载,你那句就写上执行了,啥也找不到
第二种倒是应该可以的 document.getElementById('adds')有东西吗
再有location能直接这么用吗
------解决方案--------------------
这个为什么要用c#来输出呢?直接在aspx页面添加js代码就ok了呀
还有location跳转的用法是
location.href=url 你少了个href。。。
你直接在你要操作的dom下面写
JScript code

<script type="text/javascript">
   document.getElementById('adds').style.display = 'block';
   location.href='SideDish.aspx'
</script>
