2.1 容器组件(view)

(2)例子

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>

page.wxss

.flex-item-red{  background-color: red;  height: 200rpx;  width: 200rpx;  text-align: center;  line-height: 200rpx; } .flex-item-green{  background-color: green;  height: 200rpx;  width: 200rpx;  text-align: center;  line-height: 200rpx } .flex-item-blue{  background-color: blue;  height: 200rpx;  width: 200rpx;  text-align: center;   line-height: 200rpx  } .flex-wrp-row{  flex-direction: row;  display: flex;  margin-left: 10rpx;  margin-top: 20rpx; } .flex-wrp-column{  flex-direction: column;  display: flex;  margin-left: 10rpx;   margin-top: 20rpx; } .color-text{  color: snow;  font-family: 'Times New Roman', Times, serif;  font-weight: bold; } .hover-style{  background-color: black; } .row-view-title,.column-view-title{  margin-left: 20rpx;  font-family: 'Times New Roman', Times, serif;  font-weight: bold; } /*重要属性：  display: flex; //与display：box;是类似，是flexbox的最新语法格式，有更好的适配效果  flex-direction: column; //表示子布局垂直布局  flex-direction: row; //表示子布局为水平布局 */

2.2 可滚动视图容器(scroll-view)

(1) 总结

(2) 例子

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; } /*重要属性：  white-space: nowrap;//设置内部元素不换行显示，与display: inline-flex;属性联合使用才会有水平布局的效果 */

page.js

//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  }, })

2.3 滑块视图容器（swiper）

(2)例子

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.js Page({  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) } })
