Try this

C#

var flag = '<%=Session["Time"] == null%>';
       if (flag.toLowerCase() == 'true')
       {// some code
       }
       else
       {
           // some code.
       }

Thanks kartik for ur help.I think,my logic was wrong.I wrote like this

if ('<%=Session["Time"] == null%>')
{
alert('null session');
}

Session return true or false.False means not null and true means null.I suppose to change my code if ('<%=Session["Time"] == null%>')
{
alert('Not null session');
}
