示例1: TreeWalker
const findTextNodeRelative = (dom: DOMUtils, isAfterNode: boolean, collapsed: boolean, left: boolean, startNode: Node): Option<CaretPosition> => {
let walker, lastInlineElement, parentBlockContainer;
const body = dom.getRoot();
let node;
const nonEmptyElementsMap = dom.schema.getNonEmptyElements();
parentBlockContainer = dom.getParent(startNode.parentNode, dom.isBlock) || body;
// Lean left before the BR element if it's the only BR within a block element. Gecko bug: #6680
// This: <p><br>|</p> becomes <p>|<br></p>
if (left && NodeType.isBr(startNode) && isAfterNode && dom.isEmpty(parentBlockContainer)) {
return Option.some(CaretPosition(startNode.parentNode, dom.nodeIndex(startNode)));
}
// Walk left until we hit a text node we can move to or a block/br/img
walker = new TreeWalker(startNode, parentBlockContainer);
while ((node = walker[left ? 'prev' : 'next']())) {
// Break if we hit a non content editable node
if (dom.getContentEditableParent(node) === 'false' || isCeFalseCaretContainer(node, body)) {
return Option.none();
