为什么我的弹出窗口里面的内容在IE里不显示，是有panel控件的不显示，没有panel控件的显示，
但是在火狐里都显示，请大虾帮帮忙~~~~

</asp:Panel>
<div id="sendjobdis" style="<%=displaystr%>padding-top:20px">

<input type="button" value="点击收藏职位" onclick="jobcollent(<%=request("jobid")%>,2)" id="sendjobbutton"/>
<input type="hidden" name="jobid" value="<%=request("jobid")%>" />

检测是否登录，登录了就直接显示收藏职位按纽，没有登录就显示panle的登录界面。
if (cmdck.checkuser("user", "users") == true) {
displaystr = "";
} else {
pannel1.Visible = true;
}
