[qq_36254427]

		$.ajax({
			type:"POST",
			url: SITE_URL  + '?ctl=Buyer_Order&met=addOrder&typ=json',
			data:{receiver_name:address_contact,receiver_address:address_address,receiver_phone:address_phone,invoice:invoice,invoice_id:invoice_id,cart_id:cart_id,shop_id:shop_id,remark:remark,increase_goods_id:increase_goods_id,voucher_id:voucher_id,rpt:rpt,pay_way_id:pay_way_id,address_id:address_id,seller_user_id:seller_user_id,common_recycle:common_recycle},
			dataType: "json",
			contentType: "application/json;charset=utf-8",
			async:false,
			success:function(a){
				alert(8);
				if(a.status == 200)
				{
					alert(9);
					if(pay_way_id == 1)
					{
						window.location.href = PAYCENTER_URL + "?ctl=Info&met=pay&uorder=" + a.data.uorder +"&from_app_id=" + app_id;
						return false;
					}
					else
					{
						window.location.href = SITE_URL + '?ctl=Buyer_Order&met=physical';
						return false;
					}
				}
				else
				{
					if(a.msg != 'failure')
					{
						Public.tips.error(a.msg);
					}else
					{
						Public.tips.error('订单提交失败！');
					}
				}
			},
			failure:function(a)
			{
				Public.tips.error('操作失败！');

				window.location.reload(); //刷新当前页
			}
		});

上面这一段代码，chrome和firefox，360浏览器极速模式,QQ浏览器都是正常的,但是360安全浏览器IE8兼容模式下回调函数没有执行，这是什么问题，我页面已经写了<meta name="renderer" content="webkit">

你先看看jq包的版本是否支持ie8，没有执行代码，有报错信息吗
