一、使用来自不同页面的函数
函数写在util.js页面
function formatTime(date) {var year = date.getFullYear()var month = date.getMonth() + 1var day = date.getDate()var hour = date.getHours()var minute = date.getMinutes()var second = date.getSeconds()return [year, month, day].map(formatNumber).join('/') + ' ' + [hour, minute, second].map(formatNumber).join(':')
}function formatNumber(n) {n = n.toString()return n[1] ? n : '0' + n
}
module.exports = {formatTime: formatTime,
}
使用函数的方法：
二、使用相同页面的函数
get_productInformation: function () {。。。。},
getZones:function(){this.get_productInformation},
使用app.js内定义的函数
app.js代码
//app.js
App({onLaunch: function() {//调用API从本地缓存中获取数据var logs = wx.getStorageSync('logs') || []logs.unshift(Date.now())wx.setStorageSync('logs', logs)},get_a_test:function(){console.log('this is a test')},getUserInfo: function(cb) {var that = thisif (this.globalData.userInfo) {typeof cb == "function" && cb(this.globalData.userInfo)} else {//调用登录接口wx.getUserInfo({withCredentials: false,success: function(res) {that.globalData.userInfo = res.userInfotypeof cb == "function" && cb(that.globalData.userInfo)}})}},globalData: {userInfo: null,college_change:false}
})
三、在其他页面中使用
