vue的基本用法

标签：erro   参数   attribute   return   ado   cli   com   用法   err   

公共样式---pc版的404报错

动态src
这个是vue组件template部分

 <div class="not-found">
        <img :src="img" alt="404">
    </div>
     <div>{{fish}}</div>

script部分

import './404.css'   //先引入less
import img from './error-404.png'
export default {
  name: 'HelloWorld',
  data () {
    return {
      msg: '你还没有登录,请先登录',
      img, //es6用法   等同于  img:img
      fish:'你好'
    }
  }
}

引入的404.css部分

.not-found {
    margin: 10% 0 0;
    text-align: center;
}

下面是现象

公共样式loading pc端，根据传过来的参数，来显示loading
style用法
父组件:

<template>
     <!-- 显示loading -->
     <Load :option="test"></Load>
  </div>
</template>
<script>
import load from './loading'
export default {
  name: 'HelloWorld',
  data () {
    return {
      msg: '你还没有登录,请先登录',
      test:{
        show:true,
        progress:60
      }
    }
  },
  components:{
    Load:load
  }
}
</script>

子组件

<template>
  <div class="hello">
     哈哈哈
     <!-- 显示loading -->
    <div class="loadingbar-wrapper" v-show="option.show">
        <div id="loadingbar" class="waiting" :style="{ width: option.progress+'%'}">
            <dt></dt><dd></dd>
        </div>
    </div>
     
  </div>
</template>

<script>

export default {
  name: 'HelloWorld',
  props:['option'],
  data () {
    return {
      msg: '你还没有登录,请先登录'
    }
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>

效果 :

这个位置会根据传过来的数不一样而移动，这里主要是父传子的实际应用吧~
