随机生成 UUID

1、随机生成 UUID主方法

/*** 随机生成 UUID* @param {*} len   生成字符串的长度* @param {*} radix  生成随机字符串的长度**/export function uuid_(len = 30, radix = 20) {var chars ='0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.split('')var uuid = [],iradix = radix || chars.lengthif (len) {// Compact formfor (i = 0; i < len; i++) uuid[i] = chars[0 | (Math.random() * radix)]} else {// rfc4122, version 4 formvar r// rfc4122 requires these charactersuuid[8] = uuid[13] = uuid[18] = uuid[23] = '-'uuid[14] = '4'// Fill in random data.  At i==19 set the high bits of clock sequence as// per rfc4122, sec. 4.1.5for (i = 0; i < 36; i++) {if (!uuid[i]) {r = 0 | (Math.random() * 16)uuid[i] = chars[i == 19 ? (r & 0x3) | 0x8 : r]}}}return uuid.join('')
}

2、使用 uuid: uuid_()

import {uuid_} from '@/utils/uuid'
// 定义一个辅助函数来处理雨前和雨中的数据processList(dataList) {return (dataList || []).filter((item) => item.subCode == this.rscd).map((item) => {const defaultValues = { kd1: null, ll: null, needTm: null }const ddSz =item.ddSzList && item.ddSzList.length > 0? item.ddSzList[0]: defaultValuesreturn {...item,uuid: uuid_(),kd1: ddSz.kd1,ll: ddSz.ll,needTm: ddSz.needTm}})}

3、得到"uuid": “2878J1AHGECHE51D11147244H69F72”
