vue全局过滤器 格式化时间

1、在main.js中定义

// 格式化时间
Vue.filter('formatDate', function (value) {
  let date = new Date(value);
  let y = date.getFullYear();
  let MM = date.getMonth() + 1 + "";
  MM = parseInt(MM) < 10 ? "0" + MM : MM;
  let d = date.getDate() + "";
  d = parseInt(d) < 10 ? "0" + d : d;
  let h = date.getHours() + "";
  h = parseInt(h) < 10 ? "0" + h : h;
  let m = date.getMinutes() + "";
  m = parseInt(m) < 10 ? "0" + m : m;
  let s = date.getSeconds() + "";
  s = parseInt(s) < 10 ? "0" + s : s;
  return y + "-" + MM + "-" + d + " " + h + ":" + m + ":" + s;
})

2、在组件中使用

<el-table-column property="lastUpdateTime" label="上次修改时间" width="180">
          <template slot-scope="scope">
            <i class="el-icon-time"></i>
            <span style="margin-left: 10px">{{ scope.row.lastUpdateTime  | formatDate }}</span>
          </template>
  </el-table-column>

结果：
2020-01-02 00:00:00
