微信小程序 UI與容器組件總結(jié)
1.總結(jié)與概述
2.容器組件
2.1 組件容器(view)
2.2 可滾動視圖容器(scroll-view)
2.3 滑塊視圖容器(swiper)
1.總結(jié)與概述
1.1 UI組件總結(jié)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(yīng)過程:事件觸發(fā)——>UI組件接收到事件——>觸發(fā)js函數(shù)響應(yīng)事件——>更新UI
2.容器組件
2.1 容器組件(view)
(1)總結(jié)
(2)例子
效果圖
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; } /*重要屬性: display: flex; //與display:box;是類似,是flexbox的最新語法格式,有更好的適配效果 flex-direction: column; //表示子布局垂直布局 flex-direction: row; //表示子布局為水平布局 */
2.2 可滾動視圖容器(scroll-view)
(1) 總結(jié)
(2) 例子
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
.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; } /*重要屬性: white-space: nowrap;//設(shè)置內(nèi)部元素不換行顯示,與display: inline-flex;屬性聯(lián)合使用才會有水平布局的效果 */
page.js
//index.js //獲取應(yīng)用實例 var app = getApp() //var color_index=['green','red','yellow','blue']; Page({ data:{ toview:'red', }, /*滑動到左邊觸發(fā)*/ scrollXToUpper:function(){ console.log('scrollXToUpper') }, /*滑動到右邊觸發(fā) */ scrollXToLower:function(){ console.log('scrollXToLower') }, /*滑動到頂部觸發(fā)*/ scrollYToUpper:function(){ console.log('scrollYToUpper') }, /*滑動到左邊觸發(fā) */ scrollYToLower:function(){ console.log('scrollYToLower') }, /*滑動觸發(fā) */ scroll:function(){ console.log("scroll") }, onLoad: function () { console.log('onLoad') var that = this }, })
2.3 滑塊視圖容器(swiper)
(1)總結(jié)
(2)例子
效果圖:
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) } })
