一.添加util.js文件
/**
* 生成uuid
*/
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("").replace("-","");
return uuid
}
//一定要在这里面注册，否则没有用
module.exports = {
wxuuid: wxuuid
}
二.页面引入js
var util = require('../../utils/util.js');
console.log(
util.wxuuid()
);
