如何将滑块与其他复选框过滤器放在一起

【中文标题】如何将滑块与其他复选框过滤器放在一起【英文标题】：How to put Slider together with additional checkbox filter 【发布时间】：2018-08-16 15:33:11 【问题描述】：我在使用 Ui 滑块和复选框过滤器时遇到问题。它应该像这样工作：
当我使用滑块设置价格目标时，我得到了一些结果。然后希望这些结果通过使用复选框的附加过滤器进行排序。毕竟我应该得到完全符合我的要求。
而不是我得到了错误的匹配。使用滑块后，我得到了我想要的，但是当使用复选框时，一切都崩溃了。我只得到复选框结果，没有滑块效果。我不知道如何强迫他们一起工作。
如果仅使用滑块（不单击复选框），我还想查看有关找到结果数量的信息。
这是 jsfiddle 示例：http://jsfiddle.net/m1z930r5/15/

它工作得几乎完美。我发现了一个假条件。当我将滑块设置为最低 500 美元并按下 1、2、3、4 复选框然后取消按下 1 时，突然我可以看到没有 4 的元素，这是我不应该看到的。我应该看到那些包含 2,3,4。你觉得那是什么？ 更新：我在 splice 调用中有错字 效果很好。我印象深刻。非常感谢。 我试图在该示例中添加额外的范围滑块，但我失败了。你能看看这个案例吗？ ***.com/questions/51916081/adding-range-slider【参考方案2】：问题是您正在添加和删除一个类slider1Hide 以显示/隐藏超出滑块范围的对象，但对复选框使用内联样式display: list-item/display: none。内联 css 样式始终优先于类中定义的样式，因此即使您的某个项目具有 slider1Hide，如果它具有 display: list-item，它仍会显示。你可以用浏览器的检查器观察这一点——你会看到一条穿过slider1Hide的display属性的线：
无论如何，为了解决您的问题，我已经更新了您的 javascript。 filterPrice() 和filterCheckboxes() 这两个函数接收产品列表并过滤掉那些应该保持隐藏的产品。那么show()的代码就是剩下的产品了。
