Helper function to manage attributes for Bootstrap's JavaScript components.
bs_set_data(tag, ...)
bs_set_aria(tag, ...)htmltools::[tag][htmltools::tag]
named arguments used to set the attributes of tag
htmltools::[tag][htmltools::tag], modified copy of tag
One of the mechanisms used by the API for Boostrap JavaScript-components is
an html elements' attributes. These attribute names are prefixed with
"data-" or "aria-", depending on the function.
When expressed in html, attributes themselves have the properties:
Logical values are expressed as "true" or "false".
Time durations are expressed as number of milliseconds.
Vector (non scalar) values are expressed in a space-delimited list.
The purpose of this function is to let you express these values in ways familiar to you as an R user. For example:
Logical values can be expressed as logicals: TRUE or FALSE.
Time durations can be expressed using lubridate durations.
Vector (non scalar) values can be expressed as vectors.
Note that this returns a modified copy of the tag sent to it, so it is pipeable.
