现在在写一个多条件筛选的功能，但发现一个很头疼的问题

                var dateList = "";
                var brandButton = $(".searchresults-list button[date-type=brand]");
                if (brandButton.lenght != 0) {
                    brandButton.each(function () {
                        var Type = $(this).attr("date-type");
                        var Data = $(this).attr("date-search");
                        dateList += "[data-" + Type + "=" + Data + "],";
                    });
                }
                var typeButton = $(".searchresults-list button[date-type=type]");
                if (cartypeButton.lenght != 0) {
                    cartypeButton.each(function () {
                        var Type = $(this).attr("date-type");
                        var Data = $(this).attr("date-search");
                        dateList += "[data-" + Type + "=" + Data + "],";
                    });
                }
                var moneyButton = $(".searchresults-list button[date-type=money]");
                if (moneyButton.lenght != 0) {
                    moneyButton.each(function () {
                        var Type = $(this).attr("date-type");
                        var Data = $(this).attr("date-search");
                        dateList += "[data-" + Type + "=" + Data + "],";
                    });
                }
                dateList = dateList.substring(0, dateList.length - 1);
                $(".carView:not(" + dateList + ")").css("display", "none");
一个类似淘宝商品筛选列表的效果
每次的遍历都会将条件累加进去
dateList += "[data-" + Type + "=" + Data + "],";
这句话条件]符号后面带了一个逗号
最终效果是只要满足所选条件，都会被显示。类似“或者||”，但跟“或者”不同的是把或者在内的都显示个边
然后不加逗号
最终效果是3个条件每个只能满足一种，其中一个条件有两种就会全不显示。类似“而且&&”，但跟“而且”不同的是他出现两个相同条件，不同值的时候就都不显示了

郁闷，其实要的效果就是同时满足所选条件才显示，但就是逻辑上想不出来了
