数字盒子

轮播图组件

<template>
	<div>
		<mt-swipe :auto="4000">
			<mt-swipe-item v-for="item in swiperList" :key="item.url">
				<img src="item.img" alt="" :class="{'full': isfull}">
			</mt-swipe-item>
		</mt-swipe>
	</div>
</template>

<script>
	export default {
		props: ["swiperList", "isfull"]
	}
</script>

<style lang="scss" scoped>
	.mint-swipe {
		height: 200px;

		.mint-swipe-item {
			&:nth-child(1){

			}
			&:nth-child(2){
				
			}
			&:nth-child(3){
				
			}

			img{
				height: 100%;
			}
		}
	}
	.full{
		width: 100%;
	}
</style>

关键问题

1. 轮播图的自适应问题：

<img src="item.img" alt="" :class="{'full': isfull}">

.full{
		width: 100%;
	}

2. 小球动画
   半场动画+ref组件操作+@change事件绑定+滚动条和分辨率适配算法

<input id="test" class="mui-input-numbox" type="number" value="1" @change="countChanged" ref="numbox"

beforeEnter(el){
				el.style.transform = "translate(0, 0)"
			},
enter(el, done){
				el.offsetWidth;
				const ballPosition = this.$refs.ball.getBoundingClientRect();
				const badgePosition = document.getElementById('badge').getBoundingClientRect();
				const xDist = badgePosition.left - ballPosition.left;
				const yDist = badgePosition.top - ballPosition.top;
				el.style.transform = `translate($(xDist)px, $(yDist)px)`;
				el.style.transition = "all 1s cubic-bezier(.4,-0.3,1,.68)";
				done();
			},
afterEnter(el){
				this.ballFlag = !this.ballFlag
			},

3. $emit 子组件向父组件传值

<p>购买数量：<numbox @getcount="getSelectedCount" 

methods:{
			countChanged(){
				this.$emit("getcount", parseInt(this.$refs.numbox.value));
			}
		},

4. watch监听max

watch:{
			'max':function(newVal, oldVal){
				mui(Selector).numbox().setOption("max", newVal)
			}
		}
