示例1: prependData
const rngSetContent = (rng: Range, fragment: DocumentFragment): void => {
const firstChild = Option.from(fragment.firstChild).map(Element.fromDom);
const lastChild = Option.from(fragment.lastChild).map(Element.fromDom);
rng.deleteContents();
rng.insertNode(fragment);
const prevText = firstChild.bind(Traverse.prevSibling).filter(Node.isText).bind(removeEmpty);
const nextText = lastChild.bind(Traverse.nextSibling).filter(Node.isText).bind(removeEmpty);
// Join start
Options.liftN([prevText, firstChild.filter(Node.isText)], (prev: Element, start: Element) => {
prependData(start.dom(), prev.dom().data);
Remove.remove(prev);
});
// Join end
Options.liftN([nextText, lastChild.filter(Node.isText)], (next: Element, end: Element) => {
const oldLength = end.dom().length;
end.dom().appendData(next.dom().data);
rng.setEnd(end.dom(), oldLength);
Remove.remove(next);
});
rng.collapse(false);
};示例2: trimEmptyTextNode
const deleteContentAndShowCaret = (editor: Editor, range: Range, node: Node, direction: HDirection, forward: boolean, peekCaretPosition: CaretPosition) => {
const caretRange = CefUtils.showCaret(direction, editor, peekCaretPosition.getNode(!forward) as Element, forward, true);
