利用util.js 生成 UUID 并实现调用:
下面是util.js
const wxuuid = function () { var s = []; var hexDigits = "0123456789abcdef"; for (var i = 0; i 36; i++) { s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1); } s[14] = "4"; // bits 12-15 of the time_hi_and_version field to 0010 s[19] = hexDigits.substr((s[19] & 0x3) | 0x8, 1); // bits 6-7 of the clock_seq_hi_and_reserved to 01 s[8] = s[13] = s[18] = s[23] = "-"; var uuid = s.join(""); return uuid}//一定要在这里面注册,否则没有用module.exports = { formatTime: formatTime, wxuuid: wxuuid}在目标JS中引用:
//在需要的UUID的JS中引用,'../'视你的目录结构而定var app=getApp()var util = require('../../utils/util.js')//调用util.wxuuid(). app.data.user.bzz[0].uuid 是我在app.js中定义的全局变量。app.data.user.bzz[0].uuid = util.wxuuid()
