1.1 UI組件總結圖
1.2 概述
小程序的UI組件也就是定義用戶界面的一系列標簽,類似于html標簽。一個完整用戶響應過程:事件觸發――>UI組件接收到事件――>觸發js函數響應事件――>更新UI
2.容器組件

page.wxml
<view> <text class="row-view-title">水平布局:</text> <view class="flex-wrp-row"> <view class="flex-item-red" hover="true" hover-class="hover-style"><text class="color-text">red</text></view> <view class="flex-item-green" hover="true" hover-class="hover-style"><text class="color-text">green</text></view> <view class="flex-item-blue" hover="true" hover-class="hover-style"><text class="color-text">blue</text></view> </view></view><view> <text class="column-view-title">垂直布局:</text> <view class="flex-wrp-column" > <view class="flex-item-red" hover="true" hover-class="hover-style"><text class="color-text" >red</text></view> <view class="flex-item-green" hover="true" hover-class="hover-style"><text class="color-text">green</text></view> <view class="flex-item-blue" hover="true" hover-class="hover-style"><text class="color-text">blue</text></view> </view></view>

效果圖:

page.wxml
<view><text>水平滾動布局</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>垂直滾動布局</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

//index.js//獲取應用實例var app = getApp()//var color_index=['green','red','yellow','blue'];Page({ data:{ toview:'red', },/*滑動到左邊觸發*/scrollXToUpper:function(){ console.log('scrollXToUpper')},/*滑動到右邊觸發 */scrollXToLower:function(){ console.log('scrollXToLower')},/*滑動到頂部觸發*/scrollYToUpper:function(){ console.log('scrollYToUpper')},/*滑動到左邊觸發 */scrollYToLower:function(){ console.log('scrollYToLower')},/*滑動觸發 */scroll:function(){ console.log("scroll")},onLoad: function () { console.log('onLoad') var that = this },})2.3 滑塊視圖容器(swiper)
