使用Vue-cli 中为单独页面设置背景图片铺满全屏
啥也不说了,大家还是直接看代码吧~
<template> <div id="logo"> </div> </template> <script> import meadiaurl from '../../api/mediaurl' export default { name: "logo" </script> <style scoped> #logo{ background: url("../../assets/images/Login.png"); background-size: 100% 100%; height: 100%; } </style>
如果像以上代码写,高度为100%时,会发现背景图片只是内容撑起来的,却不能使整个屏幕铺满背景图;
解决方案:
我们要让#logo脱离文档流,为他添加个fixed属性
#logo{ background: url("../../assets/images/Login.png"); background-size: 100% 100%; height: 100%; position: fixed; width: 100% }
补充知识:vue 实现全屏显示和全屏按钮svg图
1,第一步安装screenfull
npm install --save screenfull
2, 新建screenfull.vue组件,
<template> <div> <svg t="1508738709248" class="screenfull-svg" viewBox="0 0 1024 1024" version="1.1" xmlns="http://www.w3.org/2000/svg" p-id="2069" xmlns:xlink="http://www.w3.org/1999/xlink" width="32" height="32" @click="click"> <path d="M333.493443 428.647617 428.322206 333.832158 262.572184 168.045297 366.707916 64.444754 64.09683 64.444754 63.853283 366.570793 167.283957 262.460644Z" p-id="2070"/> <path d="M854.845439 760.133334 688.61037 593.95864 593.805144 688.764889 759.554142 854.56096 655.44604 958.161503 958.055079 958.161503 958.274066 656.035464Z" p-id="2071"/> <path d="M688.535669 428.550403 854.31025 262.801405 957.935352 366.921787 957.935352 64.34754 655.809313 64.081481 759.919463 167.535691 593.70793 333.731874Z" p-id="2072"/> <path d="M333.590658 594.033341 167.8171 759.804852 64.218604 655.67219 64.218604 958.270996 366.342596 958.502263 262.234493 855.071589 428.421466 688.86108Z" p-id="2073"/> </svg> </div> </template> <script> import screenfull from 'screenfull' //引入screenfull export default { name: 'Screenfull', props: { width: { type: Number, default: 22 }, height: { type: Number, default: 22 }, fill: { type: String, default: '#48576a' } }, data(){ return { isFullscreen: false //不可少 } }, methods: { click(){ if(!screenfull.enabled){ this.$message({ message: '你的浏览器不支持全屏', type: 'warning' }) return false } screenfull.toggle() } } } </script> <style scoped> .screenfull-svg { width: 20px; height: 20px; cursor: pointer; fill: red; } </style>
3, 在需要的组件引入该组件即可
