html - ShinyDashboard 中的 CSS Reactive ValueBoxes

转载作者：行者123 更新时间：2023-11-28 14:34:19

我正在尝试使用 css 在 shinydashboard 中自定义 valueboxes。我发现的问题是:

我无法标记一个特定的 valuebox，这使得任何 css 更改都适用于所有
我不知道如何根据服务器端的输入使 css 响应

下面是我的代码，说明了我正在尝试做的事情。每个值框都应该有不同颜色的数字百分比字体。

最佳答案

我使用 shinjys 和 addClass/removeClass 函数来添加一个 css 类。 3 个 css 类(白色、黄色、红色)是根据 valueBox 的值预定义和分配的。

在该分配之前，您必须删除所有那些潜在的类，否则它只会附加 css-classes，然后颜色不会改变。

此示例显示了使用 2 个 valueBoxes 和 2 个 sliderInputs 更改 valueBoxes 的值的行为。

更新:shinyjs 需要在 UI 中调用 useShinyjs()。
