Remove the text in a shiny::textInput field on mouse click event

Question

I have a simple textInput:

textInput(inputId = "input1", h4("Name"), value = "Your name")

How can I set an onclick event so that the text completely disappears when the user clicks on the text field? Is this possible via shinyjs::onclick ?

Answer 1

您可以在textInput使用placeholder选项

textInput(inputId =  "input1", label = h4("Name"), placeholder = "Please provide your name...")
