微信小程序模块的使用教程,微信小程序功能开发

//JS代码var msg = "hello world";//commonjs模块化导出var num = function (num1, num2) { return num1 + num2;}var toFixed = function(value,count){ return value.toFixed(count);}var formatNumber = function (n) { n = n.toString() return n[1] ? n : '0' + n}var regYear = getRegExp("(y+)", "i");var dateFormat = function (timestamp, format) { if (!format) { format = "yyyy-MM-dd hh:mm:ss"; } timestamp = parseInt(timestamp); var realDate = getDate(timestamp); function timeFormat(num) { return num < 10 ?
