<template>

    <div class="plan_name Upload_name">企业logo</div>
    <div class='Upload'>
     <input type="file" name="pclogo" id="xdaTanFileImg" @change="xmTanUploadImg()" ref='box' accept="image/*">
     <img src="../../static/img/Authentication/shxy.jpg" class="img-circle img-thumbnail img-responsive" id="avarimgs">

export default {

//上传图片
  xmTanUploadImg(){
 
   var obj=this.$refs.box;//获取元素的dom
   var file = obj.files[0];        
   var reader = new FileReader();
   reader.onload = function (e) {
 
    var img = document.getElementById("avarimgs");//获取图片id
 
    img.src = e.target.result;//给图片src路径赋值
 
    //重要：这里可以把获取的src路径的 base64 格式的图片传给后端即可
   }
   
   reader.readAsDataURL(file)
  },
