持续创作，加速成长！这是我参与「掘金日新计划 · 10 月更文挑战」的第2天，点击查看活动详情

一、应用介绍

这次要分享的小程序功能为好友匹配动画界面，这是一款以交友相亲为背景的恋爱主题样式组件。

纯css样式和JS原生语法打造，支持多端的开发，小程序、H5、APP均能丝滑享受。

二、效果展示

在这里插入图片描述

三、技术与难点

3.1 基本开发环境

  • 开发框架：uniapp
  • 代码语法：vue 2、html、css3

3.2 开发要点

  • （1）头像图片的生成
    • 先引入<image>标签，配置好相应的图片路径
	 <image class="dot" src="randomImg"  style="width: 92px;height: 92px;border-radius: 50px;"></image>`

	- 	再通过CSS样式将其变成圆形
	

   -webkit-border-radius: 50%;
   -moz-border-radius: 50%;
   border-radius: 50%;

  • （2）CSS动画的引入 对于网页元素的动画效果我们使用CSS 3 动画,不太熟悉的小伙伴可以直接查看文档进行学习：CSS动画教程

    • 先声明一个放缩动画变量
@keyframes 动画变量名（taoren） {
	0% {
		-webkit-transform:scale(0) translateX(0);
		transform:scale(0) translateX(0);
		opacity:.6
	}
	5% {
		-webkit-transform:scale(1) translateX(0) translateY(-80%);
		transform:scale(1) translateX(0) translateY(-80%);
		opacity:.8
	}
	20% {
		opacity:1
	}
	30% {
		opacity:.2
	}
	32% {
		opacity:0;
		visibility:hidden
	}
	50% {
		-webkit-transform:scale(1.9) translateX(-40px) translateY(-340%);
		transform:scale(1.9) translateX(-40px) translateY(-340%)
	}
	100% {
		-webkit-transform:translateX(-100px);
		transform:translateX(-100px)
	}
}
  • 将动画变量绑定到相应的元素样式中
.相应原始的Class名称 {
	animation:taoren
}
  • （3）JS循环逻辑的控制 在元素和动画都具备的基础之上，接下来进行更重要的操作：将元素所设置的动画按照特定的规则进行重复播放。
    • JS中要实现重复播放的逻辑，通常的做法是使用setInterval方法。
			this.interval = setInterval((function() {
				// 动画逻辑
				}
			), this.intervalTime)

四、完整源码

代码基于vue 2语法编写，拷贝出来需保存为.vue文件。该示例代码中，包括三大模块：<script>,<template>,<style>，三大模块的作用分别是：控制元素逻辑和数据绑定,编写组织页面元素的渲染,控制和渲染元素的样式。

<template>
	<view class="center">
		<view class="container">
			<image class="dot" src="randomImg"  style="width: 92px;height: 92px;border-radius: 50px;"></image>

			<view class="pulse1"></view>
			<view class="prize-flying" >
				<view v-for="(item,index) in flyLeftList" class="fly-prize fly-left" 
				:style="{ 'background': 'url('+ item.img +')', '-webkit-animation-duration': flySpeed + 's','animation-duration': flySpeed + 's' }"></view>
				<view v-for="(item,index) in flyCenterList" class="fly-prize fly-center"
				:style="{ 'background': 'url('+ item.img +')', '-webkit-animation-duration': flySpeed + 's','animation-duration': flySpeed + 's' }"></view>
				<view v-for="(item,index) in flyRightList" class="fly-prize fly-right"
				:style="{ 'background': 'url('+ item.img +')', '-webkit-animation-duration': flySpeed + 's','animation-duration': flySpeed + 's' }"></view>
			</view>
		</view>
		<view class="flex justify-center items-center match-button" @click="showMan">
			<view class="match-btn">

			</view>
		</view>
    </view>
</template>

<script>
	import utils from '@/utils/utils'
	export default {
		components: {utils},
		data() {
			return {
				show:false,
				randomImg:'/static/imgs/mm1.jpg',
				flyLeftList: [],
				flyCenterList: [],
				flyRightList: [],
				userList:[{img:'/static/imgs/mm1.jpg'},{img:'/static/imgs/mm2.jpg'},{img:'/static/imgs/mm3.jpg'}],
				flySpeed: 25,
				indexRecord: 0,
				intervalTime: 2.5,
				interval: null,
			};
		},
		// 从后台进入前台显示
		onShow() {
			this.flyLeftList=[];
			this.flyCenterList=[];
			this.flyRightList=[];
			this.refreshUser();
		},
		// 从前台进入后台
		onHide() {
			this.flyLeftList=[];
			this.flyCenterList=[];
			this.flyRightList=[];
			clearInterval(this.interval);
		},
		methods:{
			showMan(){
				console.log('========')
				this.show =true
			},
			refreshUser(){
				this.flyInterval();
			},
			flyInterval() {
				if(this.interval != null){
					clearInterval(this.interval);
				}
				var t = this;
				this.pushFlyList(),
				this.interval = setInterval((function() {
					t.pushFlyList()
				}
				), 1e3 * this.intervalTime)
			},
			pushFlyList() {
				var t = 0;
				while (t < 3) {
					this.indexRecord == this.userList.length - 1 ? this.indexRecord = 0 : this.indexRecord++;
					var a = this.userList[this.indexRecord];
						switch (t) {
							case 0:
								this.flyLeftList.push(a);
								break;
							case 1:
								this.flyCenterList.push(a);
								break;
							case 2:
								this.flyRightList.push(a);
								break
						}
					t++	
				}
			},
		}
	}
