1.2 概述
小程式的UI元件也就是定義使用者介面的一系列標籤,類似html標籤。一個完整使用者回應過程:事件觸發->UI元件接收到事件->觸發js函數回應事件->更新UI

2.3 滑桿檢視容器(swiper)
(2)範例
效果圖:
page.wxml#########//index.js //获取应用实例 var app = getApp() //var color_index=['green','red','yellow','blue']; Page({ data:{ toview:'red', }, /*滑动到左边触发*/ scrollXToUpper:function(){ console.log('scrollXToUpper') }, /*滑动到右边触发 */ scrollXToLower:function(){ console.log('scrollXToLower') }, /*滑动到顶部触发*/ scrollYToUpper:function(){ console.log('scrollYToUpper') }, /*滑动到左边触发 */ scrollYToLower:function(){ console.log('scrollYToLower') }, /*滑动触发 */ scroll:function(){ console.log("scroll") }, onLoad: function () { console.log('onLoad') var that = this }, })######## page.js############## page.js#### #####
