        $("#btnNextWeek").click(function (e) {
            var MealsButton = $('.arrayinput');
            var Meals = s.split('!~!');
            for (var i = 0; i <= 2; i++) {
 
                MealsButton[i].css("color", "black");
                MealsButton[i].css("width", "200px");
                MealsButton[i].css("height", "60px");
 
                if (Attr[1] == "1") {
                    MealsButton[i].css("class", "btn-app btn-success btn arrayinput");
                    MealsButton[i].css("Buy", Attr[4] + ":" + Attr[3]);
                    MealsButton[i].val("خریدژتون");
                }
 
                elseif (Attr[2] == "1" && Attr[5] != "empty chip") {
                    MealsButton[i].css("class", "btn-app btn-free btn arrayinput");
                    MealsButton[i].css("DelBtn", Attr[5]);
                    if (Attr[6] != "empty chip") {
                        if (Attr[6] != "empty chip") {
                            MealsButton[i].val(Attr[6]);
 
                        }
 
                        else {
                            MealsButton[i].css("class", "btn-app btn-disable btn arrayinput");
 
                            if (Attr[6] != "empty chip") {
                                MealsButton[i].val(Attr[6]);
                            }
                            else {
