vue项目中loadsh库常用方法说明

npm i lodash

import _ form lodash

import { 要使用的函数 } from lodash

var objects = [{ 'a': 1 }, { 'b': 2 }];
 
var deep = _.cloneDeep(objects);
console.log(deep[0] === objects[0]);
// => false

_.chunk(array, [size=1])

_.chunk(['a', 'b', 'c', 'd'], 2);
// => [['a', 'b'], ['c', 'd']]
 
_.chunk(['a', 'b', 'c', 'd'], 3);
// => [['a', 'b', 'c'], ['d']]

_.compact([0, 1, false, 2, '', 3]);
// => [1, 2, 3]

var array = [1];
var other = _.concat(array, 2, [3], [[4]]);
 
console.log(other);
// => [1, 2, 3, [4]]
 
console.log(array);
// => [1]

_.drop(array, [n=1])

_.drop([1, 2, 3]);
// => [2, 3]
 
_.drop([1, 2, 3], 2);
// => [3]
 
_.drop([1, 2, 3], 5);
// => []
 
_.drop([1, 2, 3], 0);
// => [1, 2, 3]

_.dropRight(array, [n=1])

_.dropRight([1, 2, 3]);
// => [1, 2]
 
_.dropRight([1, 2, 3], 2);
// => [1]
 
_.dropRight([1, 2, 3], 5);
// => []
 
_.dropRight([1, 2, 3], 0);
// => [1, 2, 3]

_.debounce(func, [wait=0], [options=])

 searchText: {
      // lodash中的debounce防抖处理
      handler: debounce(function (val) {
        this.localSearchSuggestions(val)
      }, 300),
      // handler (val) {
      //   this.localSearchSuggestions(val)
      // },
      immediate: true
    }

_.merge(object, [sources])

var object = {
  'a': [{ 'b': 2 }, { 'd': 4 }]
};
 
var other = {
  'a': [{ 'c': 3 }, { 'e': 5 }]
};
 
_.merge(object, other);
// => { 'a': [{ 'b': 2, 'c': 3 }, { 'd': 4, 'e': 5 }] }
