[英]Shiny conditional input panel with vector
I am looking to create a conditional panel in shiny that becomes active if the input that user selects from a list (ie selectInput function) belongs to another vector.我希望在 shiny 中创建一个条件面板,如果用户从列表中选择的输入(即 selectInput 函数)属于另一个向量,该面板将变为活动状态。
I am aware that the condition in the conditional panel is a javascript element, however I cannot make it work.我知道条件面板中的条件是 javascript 元素,但我无法使其工作。
Can someone help?有人可以帮忙吗?
Here is the UI part of the code under examination:这是正在检查的代码的 UI 部分:
legs1 <- c("HOUSE","VILLA","ATTICO")
selectInput("strategy", "Strategy:", choices = df[,6]),
conditionalPanel(
condition = 'input.strategy && input.strategy.indexOf("legs1") > -1',
textInput("Leg1", "Leg1",value = ""),
textInput("Leg2","Leg2", value =""),
),
If you don't have to access the vector from within the condition it should work by using如果您不必从条件内访问向量,它应该通过使用
condition = "input.strategy && ['HOUSE', 'VILLA', 'ATTICO'].indexOf(input.strategy) > -1"
