Question

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：

使用滑块设置价格目标时，我得到了一些结果。然后，希望使用复选框通过其他过滤器对这些结果进行排序。毕竟，我应该完全符合我的要求。

相反，我得到了错误的比赛。使用滑块后，我得到了想要的东西，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。

如果只使用了滑块（未单击复选框），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/

尝试一下：

我对您的代码进行了很多重构，以使其更易于阅读/理解并保持干燥。我能够将行数从273行减少到73。

问题是您要添加和删除类slider1Hide以显示/隐藏超出滑块范围的对象，但对复选框使用嵌入式样式display: list-item / display: none 。内联css样式始终优先于类中定义的样式，因此，即使您的一个项目具有slider1Hide，如果它具有display: list-item，它仍将显示。您可以使用浏览器的检查器进行观察，您会看到display的{{1}}属性中的一行：

无论如何，为了解决您的问题，我已经更新了您的JavaScript。 slider1Hide和filterPrice()这两个功能可以获取产品列表，并过滤掉那些应该隐藏的产品。然后，代码filterCheckboxes()就是剩余的产品。
