试图用复选框过滤掉结果

Question

所以我有这些 div 本质上是结果，我正在尝试使用复选框和数据类别标签过滤上述结果。

这是我在下面使用的代码，除了它应该只显示 div，如果它的数据类别标签匹配所有复选框 selected。但是在这个脚本中，如果你 select boditrak、trackman 和 indoor 它将显示每个结果，其中任何一个都不仅仅是包含每个标签的结果

Answer 1

问题在于逗号 ,，您在 selector 变量中的每个 [data-category~=] 之间添加了它。所以 jQuery 正在寻找具有这些 data-category 中任何一个的元素。所以只需删除逗号，然后只有 jQuery 会开始寻找那些具有所有这些 data-category

的元素

您的选择器值应该是 [data-category~='trackman'][data-category~='boditrak'] 而不是 [data-category~='trackman'],[data-category~='boditrak']

var byProperty = [];

        $("input[name=sq-filter]").on( "change", function() {
            if (this.checked) byProperty.push("[data-category~='" + $(this).attr("value") + "']");
            else removeA(byProperty, "[data-category~='" + $(this).attr("value") + "']");
        });


        $("input").on( "change", function() {
