tagAppendChild: Modify tag contents

In htmltools: Tools for HTML

Modify tag contents

Description

Modify the contents (aka children) of a tag object.

Usage

tagAppendChild(tag, child, .cssSelector = NULL)

tagAppendChildren(tag, ..., .cssSelector = NULL, list = NULL)

tagSetChildren(tag, ..., .cssSelector = NULL, list = NULL)

tagInsertChildren(tag, after, ..., .cssSelector = NULL, list = NULL)

Arguments

tag	a tag object.
child	A child element to append to a parent tag.
.cssSelector	A character string containing a CSS selector for targeting particular (inner) tags of interest. At the moment, only a combination of type (e.g, div), class (e.g., .my-class), id (e.g., ⁠#myID⁠), and universal (*) selectors within a given simple selector is supported. Note, if .cssSelector is used, the returned tags will have their ⁠$children⁠ fields flattened to a single list() via tagQuery().
...	a collection of child elements.
list	Deprecated. Use ⁠!!!⁠ instead to splice into ....
after	an integer value (i.e., subscript) referring to the child position to append after.
