vue数据大屏适配
1、不管使用的是px,还是百分比,均可通过css3中提供的scale方法,来达到适配多端。
// 屏幕适配 mixin 函数 // * 默认缩放值 const scale = { width: '1', height: '1', } // * 设计稿尺寸(px) const baseWidth = 1920 const baseHeight = 1080 // * 需保持的比例(默认1.77778) const baseProportion = parseFloat((baseWidth / baseHeight).toFixed(5)) export default { data() { return { // * 定时函数 drawTiming: null } }, mounted () { this.calcRate() window.addEventListener('resize', this.resize) }, beforeDestroy () { window.removeEventListener('resize', this.resize) }, methods: { calcRate () { const appRef = this.$refs["appRef"] if (!appRef) return // 当前宽高比 const currentRate = parseFloat((window.innerWidth / window.innerHeight).toFixed(5)) if (appRef) { if (currentRate > baseProportion) { // 表示更宽 scale.width = ((window.innerHeight * baseProportion) / baseWidth).toFixed(5) scale.height = (window.innerHeight / baseHeight).toFixed(5) appRef.style.transform = `scale(${scale.width}, ${scale.height}) translate(-50%, -50%)` } else { // 表示更高 scale.height = ((window.innerWidth / baseProportion) / baseHeight).toFixed(5) scale.width = (window.innerWidth / baseWidth).toFixed(5) appRef.style.transform = `scale(${scale.width}, ${scale.height}) translate(-50%, -50%)` } } }, resize () { clearTimeout(this.drawTiming) this.drawTiming = setTimeout(() => { this.calcRate() }, 200) } }, }
2、使用:直接在mixins中引入即可
