前言
前端开发有时会处理一部分后台返回的数据,或者根据数据判断做一些处理;
这个时候就非常有必要将一些常用的工具类封装起来;
本文根据常用的一些工具类封装了 59 个方法,当然还有很多用的较少前期没有录入,后期持续跟新;
使用
1.方法一
npm i -S utils-lan
import utils from 'utils-lan'
console.log(utils.arrJudge(['1','2']))
复制代码
3.关于类名
是根据字面量来命名的,方法首个驼峰表示所属类型,后面是方法作用;
如 arrAndSet 一看就是数组的方法,是处理交集的;
如果实在难以忍受,可以采用方法 2,导入本地对项目进行更改.
arr
1.arrAndSet
并集
/**
* 数组并集,只支持一维数组
* @param {Array} arrOne
* @param {Array} arrTwo
*/
export const arrAndSet = (arrOne, arrTwo) => {
return arrOne.concat(arrTwo.filter(v => !arrOne.includes(v)))
}
复制代码
2.arrIntersection
交集
/**
* 数组交集,只支持一维数组
* @param {Array} arrOne
* @param {Array} arrTwo
*/
export const arrIntersection = (arrOne, arrTwo) => {
return arrOne.filter(v => arrTwo.includes(v))
}
复制代码
3.arrDifference
差集
/**
* 数组差集,只支持一维数组
* @param {Array} arrOne
* @param {Array} arrTwo
* eg: [1, 2, 3] [2, 4, 5] 差集为[1,3,4,5]
*/
export const arrDifference = (arrOne, arrTwo) => {
return arrOne.concat(arrTwo).filter(v => !arrOne.includes(v) || !arrTwo.includes(v))
}
复制代码
4.arrTwoToArrObj
两个数组合并成一个数组对象
/**
* 两个数组合并成一个对象数组,考虑到复杂度,所以目前支持两个一维数组
* @param {Array} arrOne
* @param {Array} arrTwo
* @param {oneKey} oneKey 选填,如果两个都未传,直接以 arrOne 的值作为 key,arrTwo 作为 value
* @param {twoKey} twoKey
*/
export const arrTwoToArrObj = (arrOne, arrTwo, oneKey, twoKey) => {
if(!oneKey&&!twoKey){
return arrOne.map((oneKey, i) => ({ [oneKey]:arrTwo[i] }))
// 或者,此方法针对将 arrTwo 的索引作为 key 的情况,arrTwo 值会覆盖 arrOne
// return Object.assign({}, arrOne, arrTwo)
}else{
return arrOne.map((oneKey, i) => ({ oneKey, twoKey: arrTwo[i] }))
}
}
