Question

我正在尝试将两个同位素过滤功能（combination filtering via checkbox和quick search）结合起来，但没有运气。我的尝试在这里：https://codepen.io/anon/pen/WJvmaj，这是两个提到的功能演示的组合。

目前搜索设置为返回searchResult和checkboxResult，后者在我可以告诉的代码中没有正确定义，而且存在我的问题：我是不确定要将checkboxResult变量设置为什么，以便它定位复选框过滤返回的内容。

Answer 1

检查元素是否包含使用.includes()在搜索输入中输入的文本，以及该元素是否具有复选框值中所选的任何类。

    filter: function() {
        var $this = $(this)
        var checkText = text == '' ? true : $this.text().includes(text)
        var checkClass = inclusives.length == 0 ? true : false;
        $.each(inclusives, function(index, c) {
            var _class = $this.hasClass(c)
            if (_class) {
                checkClass = true;
                return;
            }
