（三十二）订单管理-查询订单详情

查询订单详情
        点击每一个订单后面的订单详情,将该订单的oid通过ajax传递到后台查询
    步骤分析:
        给按钮添加事件

        <script type="text/javascript">
                function showDetail(oid){
                    //alert(oid);
                    $.post("${pageContext.request.contextPath}/adminOrder",{"method":"getDetailByOid","oid":oid},function(data){
                        var s="<table width=‘99%‘ border=‘1‘><tr><th>商品名称</th><th>购买数量</th></tr>";
                        $(data).each(function(){
                            s+=("<tr><td>"+this.product.pname+"</td><td>"+this.count+"</td></tr>");
                        });
                        s+="</table>";
                        
                        layer.open({
                             type: 1,//0:信息框; 1:页面; 2:iframe层;    3:加载层;    4:tip层
                             title:"订单详情",//标题
                             area: [‘450px‘, ‘300px‘],//大小
                             shadeClose: true, //点击弹层外区域 遮罩关闭
                             content: s//内容
                        });
                    },"json");
                }
        </script>
