When passing values, can Channels be passed through data together?
var Channels=new Array();

        $("input:checkbox[name=websiteChannel]:checked").each(function(i){
            if($(this).val()=="其他"){
                Channels[i]=$("#fuxuankuang").val();
            }else{
                Channels[i]=$(this).val();
            }

if(checkOrder()){

            confirm('确定要提交备案吗？', function(){
                $.ajax({
                    type: "POST",
                    url: url,
                    data: JSON.stringify(vm.websiteApplyOrder),
                    success: function(r){
                        if(r.code === 0){
                            alert('操作成功', function(index){
                                location.href='/website/applyOrder/website_apply_order.html';
                            });
                        }else{
                            alert(r.msg);
                        }
                    }
                });
            });
        }
