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
