  if (timeout) {
    clearTimeout(timeout);
    timeout = null;
  }
  currentValue = value;

  function fake() {
    const str = querystring.encode({
      code: 'utf-8',
      q: value,
    });
    jsonp(`https://suggest.taobao.com/sug?${str}`)
      .then(response => response.json())
      .then(d => {
        if (currentValue === value) {
          const { result } = d;
          const data = [];
          result.forEach(r => {
