我用的是蓝色公安局网站模板，我在留言反馈输入东西后，可以返回查询码。之后我在后台回复和审核通过，在前台通过查询码查询后，页面一闪就没了。
代码一下：
<div class="hdjl-search">
<div class="fm">
<form name="form_search" method="post">
<span>查询码：</span><input class="stb" id="s_code" name="s_code" value="请输入查询码" onfocus="if(this.value=='请输入查询码')this.value=''" /> <br />
<p>
<input id="button" value="搜索" class="sbt" onclick="return s_letter()" type="submit" /><a style="margin:0px;background
B7B7B7;margin-left:2px;" class="sbt" href="#">返回</a>
</p>
</form>
<ul class="sm">
<li>
说明：1、若查询信息设置为“不公开”，则需要填写受理编号和用户密码；
</li>
<li>
2、若查询信息设置为“公开”，则无需填写用户密码即可查看反馈信息；
</li>
<li>
3、填写用户密码的用户可对答复信息进行满意度评价。
</li>
</ul>
</div>
</div>
<script>
function s_letter()
{
var s_code=Id("s_code");
if(Trim(s_code.value)=="" || Trim(s_code.value)=="请输入查询码")
{
alert("请输入查询码!");
s_code.focus();
return false;
}
return true;
}
</script>
