TDOMNode_WithChildren.SetTextContent procedure

Declaration

procedure SetTextContent(const AValue: DOMString); override

Arguments

Description

SetTextContent is a overridden method used to set the TextContent property to the value specified in AValue. TextContent is the textual representation of the content for the node as a single TDOMText child node.

SetTextContent calls the Changing method to ensure that the node does not have the value nfReadonly in its Flags property. An EDOMError exception is raised with the NO_MODIFICATION_ALLOWED_ERR constant if the node is marked as read-only.

SetTextContent removes existing ChildNodes by calling DetachChild until FirstChild is no longer assigned.

If AValue is not an empty string (''), the OwnerDocument is used to create a TDOMText node with the specified value. The new text node is added to ChildNodes using the AppendChild method.
