// 将时间戳转日期格式的过滤器
Vue.filter('dateFormat', (dataStr) => {
  var time = new Date(dataStr);

  function timeAdd0(str) {
    if (str < 10) {
      str = '0' + str;

  var mm = time.getMinutes();
  var s = time.getSeconds();
  return y + '-' + timeAdd0(m) + '-' + timeAdd0(d) + ' ' + timeAdd0(h) + ':' + timeAdd0(mm) + ':' + timeAdd0(s);
