ajax获取网页cookie值，并处理页面信息

注：非必要情况。可直接在后台操作数据，不适用ajax更简单

　（$sn_arr = $_COOKIE;）   ---------------获取所有cookie进行筛选操作　

1.js（页面加载0.5ms后执行函数）

 $(function(){
        setTimeout(function () {
            $.ajax({
                url:"/supplierbuyer/order/getCookie",data:{
                },type:"POST",dataType:"JSON",success:function(data){
                    if(data.status==true){
                        //处理cookie的数据
                        var cookie_content = data[‘sn_arr‘];
                        $.each(cookie_content,function(index,item){
                            if (index.startsWith("order_sn_")) {
                                var order_sn = index.substr(9);
                                $(‘.‘+order_sn).text(‘‘);
                                $(‘.‘+order_sn).parent().prev().css("background","");
                            }
                        });
                    }else{
                        console.log(data);
                        return false;
                    }
                }
            });
        },0.5);

    });

2.PHP

 /**
     * 获取cookie
     */
    public function getCookie()
    {
        $sn_arr = $_COOKIE;
        if ($sn_arr) {
            $data[‘status‘] = true;
            $data[‘sn_arr‘] = $sn_arr;
            $data[‘msg‘] = ‘ok‘;
        } else {
            $data[‘status‘] = false;
            $data[‘sn_arr‘] = ‘‘;
            $data[‘msg‘] = ‘网络错误,请稍后重试~‘;
        }
        echo json_encode($data);
        exit();
    }
