這篇文章主要介紹“基于Vue3怎么實現圖片散落效果”，在日常操作中，相信很多人在基于Vue3怎么實現圖片散落效果問題上存在疑惑，小編查閱了各式資料，整理出簡單好用的操作方法，希望對大家解答”基于Vue3怎么實現圖片散落效果”的疑惑有所幫助！接下來，請跟著小編一起來學習吧！
圖片破裂效果說白了就是搞了100個div，每個div都有自己的背景圖片，通過backgroundPosition屬性來控制每個div的背景圖片方位，最后拼在一起，就像一張完整的圖片一樣，給每個div都加上動畫效果，每個div的旋轉角度不同，移動距離不同，移動方位不同來讓整個圖片像玻璃一樣散開來。
這里用到了兩個div，#break是用作為100個div的容器，#InBox是用來綁定下一張的背景圖片
<div id="animateBox" v-show="showImg"> <div id="break"></div> <div id="InBox"></div> </div>
import bgImg5 from '../../assets/img/1/y1.png'
import bgImg4 from '../../assets/img/1/y2.png'
import bgImg3 from '../../assets/img/1/y3.png'
import bgImg2 from '../../assets/img/1/y4.png'
import bgImg6 from '../../assets/img/1/y5.png'
import { ref, onMounted, onUnmounted } from 'vue'
let index = 0
onMounted(() => {
let imageSrcArr = [bgImg2, bgImg3, bgImg4, bgImg5, bgImg6]
let imgloadPromiseArr: Array<Promise<HTMLImageElement>> = []
let imageArr: Array<string> = []
for (let i = 0; i < imageSrcArr.length; i++) {
imgloadPromiseArr[i] = new Promise((resolve, reject) => {
let img = new Image()
img.src = imageSrcArr[i]
img.onload = () => {
resolve(img)
}
})
}
imgloadPromiseArr.forEach(item => {
item.then(res => {
imageArr.push(`url(${(<HTMLImageElement>res).currentSrc})`)
index = imageArr.length
})
})
})通過createElement創建200個div，每個div綁定長寬，給div添加背景圖片，使用backgroundPosition來讓整個div變得像一張圖片，給div綁定動畫效果。
for (let i = 0; i < 100; i++) {
let div = document.createElement('div')
let div1 = document.createElement('div')
div.style.width = '76px'
div.style.height = '41px' // 這里為什么是41px后面會提到
div1.style.width = '76px'
div1.style.height = '40px'
div1.style.overflow = 'hidden'
div.style.boxSizing = 'border-box'
div.style.backgroundImage = imageArr[0]
let positionX = -(i % 10) * 76 + 'px'
let positionY = -Math.floor(i / 10) * 40 + 'px'
div.style.backgroundPosition = positionX + ' ' + positionY
div.style.backgroundSize = '760px 400px'
let style = document.styleSheets[0]
style.insertRule(`@keyframes secondrotate${i}
{
0%,30%{
transform:scale(1)
}
70%
{transform: rotateX(${180 + Math.random() * 720}deg) rotateY(${180 + Math.random() * 720}deg)}
100%
{transform: rotateX(${180 + Math.random() * 720}deg) rotateY(${180 + Math.random() * 720}deg)}
}`)
style.insertRule(`@keyframes secondrotateS${i}
{
0%,32%{
transform:scale(1);opacity:1;
}70%
{transform: translateZ(${300 + Math.random() * 1500}px) translate(${(0.5 - Math.random()) * 500}px,${
(0.5 - Math.random()) * 500
}px);opacity:0}
100%
{transform: translateZ(${300 + Math.random() * 1500}px) translate(${(0.5 - Math.random()) * 500}px,${
(0.5 - Math.random()) * 500
}px);opacity:0}
}`)
div1.style.animation = `secondrotateS${i} 4.5s ease-out infinite`
div.style.animation = `secondrotate${i} 4.5s ease-out infinite`
div.style.transformOrigin = `center center`
div1.appendChild(div)
dom.appendChild(div1)
}通過zIndex來讓當前展示的div是哪一個
前面說過，InBox是展示的下一張圖片，在breakBox散落完成之后，讓breakBox的zIndex降低，展示出下一張圖片，隨后帶有100個div的breakBox完成下一張圖片的渲染，zIndex提高，展示出來
let count = 0
let repeat = true
let breakBox: HTMLDivElement = document.querySelector('#break')!
let InBox: HTMLDivElement = document.querySelector('#InBox')!
function changeImage(InBox: HTMLDivElement) {
if (repeat) {
breakBox.style.zIndex = '-10'
count++
count = count === index ? 0 : count
repeat = false
setTimeout(() => {
repeat = true
breakBox.style.zIndex = '100'
let currentImageLength = count === index - 1 ? 0 : count + 1
InBox.style.backgroundImage = imageArr[currentImageLength]
}, 1000)
}
}每次動畫完成之后會去調上面這個方法，為了能在div碎片破碎完畢，展示下一張圖片，使用定時器將該方法進行延遲處理 4s是因為div碎片在4s后完全消失。（動畫在運行70%的時候，透明度為0）
const timer1 = ref<number>()
const timer2 = ref<number>()
for (let i = 0; i < 100; i++) {
let div = document.createElement('div')
let div1 = document.createElement('div')
div.style.width = '76px'
div.style.height = '41px'
div1.style.width = '76px'
div1.style.height = '40px'
div1.style.overflow = 'hidden'
div.style.boxSizing = 'border-box'
div.style.backgroundImage = imageArr[0]
let positionX = -(i % 10) * 76 + 'px'
let positionY = -Math.floor(i / 10) * 40 + 'px'
div.style.backgroundPosition = positionX + ' ' + positionY
div.style.backgroundSize = '760px 400px'
let style = document.styleSheets[0]
style.insertRule(`@keyframes secondrotate${i}
{
0%,30%{
transform:scale(1)
}
70%
{transform: rotateX(${180 + Math.random() * 720}deg) rotateY(${180 + Math.random() * 720}deg)}
100%
{transform: rotateX(${180 + Math.random() * 720}deg) rotateY(${180 + Math.random() * 720}deg)}
}`)
style.insertRule(`@keyframes secondrotateS${i}
{
0%,32%{
transform:scale(1);opacity:1;
}70%
{transform: translateZ(${300 + Math.random() * 1500}px) translate(${(0.5 - Math.random()) * 500}px,${
(0.5 - Math.random()) * 500
}px);opacity:0}
100%
{transform: translateZ(${300 + Math.random() * 1500}px) translate(${(0.5 - Math.random()) * 500}px,${
(0.5 - Math.random()) * 500
}px);opacity:0}
}`)
div1.style.animation = `secondrotateS${i} 4.5s ease-out infinite`
div.style.animation = `secondrotate${i} 4.5s ease-out infinite`
div.style.transformOrigin = `center center`
div.addEventListener('animationstart', () => {
timer1.value = setTimeout(() => {
changeImage(InBox)
div.style.backgroundImage = imageArr[count]
}, 4000)
})
div.addEventListener('animationiteration', () => {
timer2.value = setTimeout(() => {
changeImage(InBox)
div.style.backgroundImage = imageArr[count]
}, 4000)
})
div1.appendChild(div)
dom.appendChild(div1)
}
在100個div展示之后會出現這樣的線，在經過多次嘗試之后，找到了方法，將div的高度變大，div1設置overflow:hidden; 線回消失
