Create a bootstrap tooltip

Create bootstrap tooltips for any HTML element to be used in shiny applications.

tooltip(
  refId,
  text,
  attr = NULL,
  animation = TRUE,
  delay = 100,
  html = TRUE,
  placement = "auto",
  trigger = "hover"
)

Arguments

refId

character (required): id of the element the tooltip is to be attached to.

text

character (required): Text to be displayed in the tooltip.

attr

character (optional): Attach tooltip to all elements with attribute attr='refId'.

animation

logical (with default): Apply a CSS fade transition to the tooltip.

delay

numeric (with default): Delay showing and hiding the tooltip (ms).

html

logical (with default): Insert HTML into the tooltip.

placement

character (with default): How to position the tooltip - top | bottom | left | right | auto. When 'auto' is specified, it will dynamically reorient the tooltip. For example, if placement is 'auto left', the tooltip will display to the left when possible, otherwise it will display right.

trigger

character (with default): How tooltip is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space.

Examples

# javascript code
tt <- tooltip("elementId", "This is a tooltip.")
str(tt)
#> List of 1
#>  $ :List of 3
#>   ..$ name    : chr "head"
#>   ..$ attribs : Named list()
#>   ..$ children:List of 1
#>   .. ..$ :List of 3
#>   .. .. ..$ name    : chr "script"
#>   .. .. ..$ attribs : Named list()
#>   .. .. ..$ children:List of 1
#>   .. .. .. ..$ : 'html' chr "$(window).load(function(){ $('#elementId').tooltip({ html: true, \n                  trigger: 'hover', title: '"| __truncated__
#>   .. .. .. .. ..- attr(*, "html")= logi TRUE
#>   .. .. ..- attr(*, "class")= chr "shiny.tag"
#>   ..- attr(*, "class")= chr "shiny.tag"
#>  - attr(*, "class")= chr [1:2] "shiny.tag.list" "list"
