在 flexdashboard 中，是否可以单击 valueBox 来更新文本框，例如 actionButton？

Question

我正在尝试利用valueBoxinflexdashboard来显示标题数字。但是，我也希望valueBox可以像 一样actionButton，因为单击valueBox应该会触发仪表板中其他位置的操作。

在检查flexdashboard文档时，我看到以下相关位valueBox：

关联值框

valueBox(42, icon = "fa-pencil", href="#details")

其中单击valueBox将用户导航到具有“#details”锚点的不同页面。但是，没有任何迹象表明单击valueBox可用于其他操作。

下面是一个最小的相关 flexdashboard 代码

---
title: "valueBox Links"
output: 
  flexdashboard::flex_dashboard:
runtime: shiny
---

```{r setup, include=FALSE}
library(flexdashboard)

    ```

#### Three valueBoxes

### valueBox 1
```{r}
valueBox(1)
    ```

### valueBox 2
```{r}
valueBox(2)
    ```

### valueBox 3
```{r}
valueBox(3)
    ```

Column

### Text output
This is where I want some text to show up dynamically, depending on if the user has clicked valueBox 1, 2, or 3.  

任何帮助，将不胜感激 ：）

我尝试了不同的参数，valueBox但没有任何运气。最后我设法解决了这个问题，将actionButtons 放在valueBoxes的标题中，然后使用自定义样式使它们透明并展开它们以覆盖整个valueBox. 看起来像这样，单击每个valueBox会在“文本输出”下呈现不同的文本：

我添加了颜色和图标以突出显示valueBoxes 可以正常设置样式。它只使用 flexdashboard 库，并且完全响应。这是代码：

title: "valueBox Links"
output: 
  flexdashboard::flex_dashboard:
runtime: shiny
---

```{r setup, include=FALSE}
library(flexdashboard)
```

### valueBox 1
```{r}
valueBox(1, caption = paste("I'm clickable!", actionButton("button1", " ", style = "background-color:rgba(39, 128, 227, 0.0); border-color:rgba(39, 128, 227, 0.0); position: absolute; overflow: hidden; left: 0px; top: 0px; right: 0px; bottom: 0px; width:100%")), icon = "fa-thumbs-up", color = "success")
```

### valueBox 2
```{r}
valueBox(2, caption = paste("I'm clickable too!", actionButton("button2", " ", style = "background-color:rgba(39, 128, 227, 0.0); border-color:rgba(39, 128, 227, 0.0); position: absolute; overflow: hidden; left: 0px; top: 0px; right: 0px; bottom: 0px; width:100%")), icon = "fa-tag", color = "warning")

### valueBox 3
```{r}
valueBox(3, caption = paste("ME TOO!", actionButton("button3", " ", style = "background-color:rgba(0, 0, 0, 0.0); border-color:rgba(0, 0, 0, 0.0); position: absolute; overflow: hidden; left: 0px; top: 0px; right: 0px; bottom: 0px; width:100%")), icon = "fa-random", color = "danger")

rv$data <- "A statistician’s wife had twins. He was delighted. He rang the minister who was also delighted. “Bring them to church on Sunday and we’ll baptize them,” said the minister. “No,” replied the statistician. “Baptize one. We’ll keep the other as a control."
})
