SUI.control.BaseHTMLEditControl

SUI.control.BaseHTMLEditControl implements a WYSIWIG/HTML edit control. It should provide a standardized interface to the different implementations of contenteditable in various browsers. Because of code size of the class it is splitted in two parts: this is BaseHTMLEditControl and implements all of the technical structure, the other part HTMLEditControl only implements the actions that can be performed on the content.

public

_execCommand()

Excecute standard contenteditable commands

public

The IE editor inserts font tags in the content. And since we like spans better we replace then. Note that we cripple the face attribute (f_Roman and s_100%). So we correct that too.

public

public

_getParentElementSelection(sel)

Get the parent element node (no text node) of a given selection.

public

_onLoadIframe()

This onload handler is called when the initial generated empty document was inserted into the iframe. On this onload handler we further complete the initialization process and do some more interesting things like setting the contenteditable state, event handlers, set (if any) content, etc.

On mouse-up: good chance that we've changed the selection

public

_onSelectionChange()

Try of we can detect if the cursor or selection moved to another node in the DOM tree
