This function makes it simpler to write HTML-generating code. Instead of
needing to specify tags each time a tag function is used, as in
tags$div() and tags$p(), code inside withTags is
evaluated with tags searched first, so you can simply use
div() and p().
withTags(code, .noWS = NULL)A set of tags.
Default whitespace behavior for all tags within this call to
withTags(). Setting .noWS on an individual tag fuction inside
withTags() will override the default. See tag() for complete options.
If your code uses an object which happens to have the same name as an
HTML tag function, such as source() or summary(), it will call
the tag function. To call the intended (non-tags function), specify the
namespace, as in base::source() or base::summary().
# Using tags$ each time
tags$div(class = "myclass",
tags$h3("header"),
tags$p("text")
)
#> <div class="myclass">
#> <h3>header</h3>
#> <p>text</p>
#> </div>
# Equivalent to above, but using withTags
withTags(
div(class = "myclass",
h3("header"),
p("text")
)
)
#> <div class="myclass">
#> <h3>header</h3>
#> <p>text</p>
#> </div>
# Setting .noWS for all tags in withTags()
withTags(
div(
class = "myclass",
h3("header"),
p("One", strong(span("two")), "three")
),
.noWS = c("outside", "inside")
)
#> <div class="myclass"><h3>header</h3><p>One<strong><span>two</span></strong>three</p></div>
