示例1:
Chain.binder((rect: ClientRect) => {
const middle = { x: rect.left + rect.width / 2, y: rect.top + rect.height / 2 };
const range = document.caretRangeFromPoint(middle.x, middle.y);
if (! range) {
return Result.error('Could not find a range at coordinate: (' + middle.x + ', ' + middle.y + ')');
} else {
return SelectorExists.closest(Element.fromDom(range.startContainer), selector) ? Result.value(rect) : Result.error('Range was not within: "' + selector + '". Are you sure that it is on top of the dialog?');
}
})示例2: function
const isPseudoStop = function (element) {
return SelectorExists.closest(element, [ '.' + beforeObject, '.' + afterObject ].join(','), Fun.constant(false));
};示例3: function

const rootElement = Element.fromDom(rootNode);
const startNode = Element.fromDom(node);
return SelectorExists.ancestor(startNode, 'pre,code', Fun.curry(Compare.eq, rootElement));
