The Text interface represents the textual content of Element or Attr.  If an element has no markup within its content, it has a single child implementing Text that contains the element's text.  However, if the element contains markup, it is parsed into information items and Text nodes that form its children.

New documents have a single Text node for each block of text. Over time, more Text nodes may be created as the document's content changes.  The Node.normalize() method merges adjacent Text objects back into a single node for each block of text.


Text.isElementContentWhitespace 只读 This is an obsolete API and is no longer guaranteed to work.

Returns a Boolean (en-US) flag indicatingwhether or not the text node contains only whitespace.

Text.wholeText 只读
Returns a DOMString containing the text of all Text nodes logically adjacent to this Node, concatenated in document order.


Text() Experimental
Returns a Text node with the parameter as its textual content.


Text.replaceWholeText This is an obsolete API and is no longer guaranteed to work.
Replaces the text of the current node and all logically adjacent nodes with the specified text.
Breaks the node into two nodes at a specified offset.
