Question

因此，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所述结果。

这是我在下面使用的代码，除了它的数据类别标记与所有选中的复选框匹配外，它仅显示div。但是在此脚本中，如果您选择boditrak，trackman和室内，它将显示每个结果，这些结果中的任何一个都不只是包含每个标签的结果

Answer 1

问题出在逗号 ,上，您要在[data-category~=]变量的每个selector之间添加。因此，jQuery正在寻找具有任何data-category元素的元素。因此，只需删除逗号，然后只有jQuery才会开始查找具有所有data-category

的那些元素

您的选择器值应为[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() {
            var str = "Include items \n";
