推荐答案

检查此工作代码.

var getFilter = function (category) {
    var filter = $("#filters ." + category + ":checked").map(function () {
        return '[data-filter*="' + this.value + '"]';
    }).get().join(",");
    filter = (filter.length > 0) ? filter : "*";
    return filter;
}

$("#filters :checkbox").click(function () {
    var all = $(".filterme");
    var tgts = all.filter(getFilter("brand")).filter(getFilter("class")).filter(getFilter("color"));
    all.not(tgts).hide();
    tgts.show();
});
