1.2 概述

小程序的UI组件也就是定义用户界面的一系列标签，类似于html标签。一个完整用户响应过程：事件触发——>UI组件接收到事件——>触发js函数响应事件——>更新UI

page.wxml

<view><text>水平滚动布局</text></view><view class="x-view"> <scroll-view class="scroll-view-x" scroll-x="true" bindscrolltoupper="scrollXToUpper" bindscrolltolower="scrollXToLower" bindscroll="scroll" scroll-left="0" scroll-into-view="{{green}}"> <view id="green" class="x_green"></view> <view id="red" class="x_red"></view> <view id="yellow" class="x_yellow"></view> <view id="blue" class="x_blue"></view> </scroll-view></view><view><text>垂直滚动布局</text></view><view class="y-view"> <scroll-view class="scroll-view-y" scroll-y="true" bindscrolltoupper="scrollYToUpper" bindscrolltolower="scrollYToLower" bindscroll="scroll" scroll-top="0" scroll-into-view="{{green}}"> <view id="green" class="y_green"></view> <view id="red" class="y_red"></view> <view id="yellow" class="y_yellow"></view> <view id="blue" class="y_blue"></view> </scroll-view></view>

page.wxss

.x_green{ background-color: green; width: 500rpx; height: 300rpx; display: inline-flex;}.x_red{ background-color: red; width: 500rpx; height: 300rpx; display: inline-flex; }.x_blue{ background-color: blue; width: 500rpx; height: 300rpx; display: inline-flex; }.x_yellow{ background-color: yellow; width: 500rpx; height: 300rpx; display: inline-flex; }.y_green{ background-color: green; width: 100%; height: 300rpx;}.y_red{ background-color: red; width: 100%; height: 300rpx;}.y_yellow{ background-color: yellow; width: 100%; height: 300rpx;}.y_blue{ background-color: blue; width: 100%; height: 300rpx;}.scroll-view-x{ display: flex; white-space: nowrap; width: 100%; margin-bottom: 20px; margin-top: 10px; height: 300rpx; }.scroll-view-y{ height: 400rpx;}

page.js

//index.js//获取应用实例var app = getApp()//var color_index=['green','red','yellow','blue'];Page({ data:{ toview:'red', },scrollXToUpper:function(){ console.log('scrollXToUpper')},scrollXToLower:function(){ console.log('scrollXToLower')},scrollYToUpper:function(){ console.log('scrollYToUpper')},scrollYToLower:function(){ console.log('scrollYToLower')},scroll:function(){ console.log("scroll")},onLoad: function () { console.log('onLoad') var that = this },})

2.3 滑块视图容器（swiper）

(1)总结

(2)例子

效果图：

page.wxml

<swiper data-current="0" current="0" bindchange="itemChangeFunc" circular="true" indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}"> <block wx:for="{{imgUrls}}" wx:key="swiperkeys"> <swiper-item> <image src="{{item}}" class="slide-image" width="355" height="150"/> </swiper-item> </block></swiper>

page.js

//game.jsPage({ data: { imgUrls: [ '/image/wechat.png', 'http://img02.tooopen.com/images/20150928/tooopen_sy_143912755726.jpg', 'http://img06.tooopen.com/images/20160818/tooopen_sy_175866434296.jpg', 'http://img06.tooopen.com/images/20160818/tooopen_sy_175833047715.jpg' ], indicatorDots: true, autoplay: true, interval: 3000, duration: 1000, current:1, }, durationChange: function(e) { this.setData({ duration: e.detail.value }) }, durationChange: function(e) { this.setData({ duration: e.detail.value }) },itemChangeFunc:function(e){ // console.log(e.target.dataset.current) console.log(e.detail)}})
