DOM 事件拦截，类似于 jQuery 的 delegate

import { DATA_CLICK_HIJACK_IGNORE } from '../const';

/**
 * 处理一个 hijacker 对象
 */
export default function handleClickHijacker(el, e, hijacker) {
  if (el.hasAttribute(DATA_CLICK_HIJACK_IGNORE)) {
    return false;
  }
  var condition = hijacker.condition,
    callback = hijacker.callback,
    shouldPreventDefault = hijacker.shouldPreventDefault,
    shouldStopPropagation = hijacker.shouldStopPropagation;
  var result = condition(el);
  if (!result) {
    return false;
  }
  callback === null || callback === void 0 ? void 0 : callback(el, result);
  if (typeof shouldPreventDefault === 'boolean' ? shouldPreventDefault : el.tagName === 'A') {
    // 不传 shouldPreventDefault，则默认仅对链接阻止默认行为
    e.preventDefault();
  }
  if (shouldStopPropagation) {
    // 默认不阻止冒泡
    e.stopPropagation();
  }
  return true;
}
