Vue中使用Lodash的实现示例

cnpm i -S lodash

import _ from 'lodash'
Vue.prototype._ = _

    let users = [
      { user: 'a', age: 48 },
      { user: 'b', age: 34 },
      { user: 'a', age: 42 },
      { user: 'b', age: 55 }
    ];
 
    let c = this._.orderBy(users, ['age'], ['desc']);
    console.log('age降序排列:', c);
 
    let d = _.orderBy(users, ['user', 'age'], ['desc', 'asc']);
    console.log('user降序,age升序排序:', d);

    test(
      arr1 = ['00', '01', '02', '03'],
      arr2 = [
        { value: '12', name: '00' },
        { value: '45', name: '01' },
        { value: '65', name: '03' }
      ],
      orderKey = 'name',
      order = 'asc'
    ) {
      let arr_result = arr2.map((d) => d.name);
      let a = arr1.filter((item) => !arr_result.includes(item));
      if (a.length !== 0) {
        a.forEach((item) => {
          arr2.push({ value: '0', name: item });
        });
      }
      return _.orderBy(arr2, [orderKey], [order]);
    },
