Converts the provided HTML string to a view tree.
Parameters
data : String
An HTML string.
Returns
Node | DocumentFragment | null
A converted view element.
-
useFillerType( type )
If the processor is set to use marked fillers, it will insert
fillers wrapped in<span>
elements (<span data-cke-filler="true"> </span>
) instead of regular
characters.This mode allows for a more precise handling of the block fillers (so they do not leak into the editor content) but bloats the editor data with additional markup.
This mode may be required by some features and will be turned on by them automatically.
Parameters
type : 'default' | 'marked'
Whether to use the default or the marked
block fillers.
-
_toDom( data ) → DocumentFragment
private
Converts an HTML string to its DOM representation. Returns a document fragment containing nodes parsed from the provided data.
Parameters
data : String
Returns
DocumentFragment
