上傳數(shù)據(jù)到服務器出現(xiàn)瀏覽器崩潰問題

上傳數(shù)據(jù)比較多，其中包括2到3個base64

相關代碼

  <Upload :show-upload-list="true" :headers="{'token':user}" 
  accept="application/pdf"
  multiple
  action="http://jsonplaceholder.typicode.com/posts/"
  :on-success="handleSuccess" 
  :before-upload="handleBeforeUpload">
  <Button type="ghost" icon="ios-cloud-upload-outline">文件上傳</Button>
  </Upload>
          
handleBeforeUpload(file) {
  var reader = new FileReader();
  reader.readAsDataURL(file);

  reader.onloadend = () => {
    this.upList.push(reader.result);
    this.$set(this.list, "value", this.upList);

    console.log(this.list);
  };

  return false;
},

數(shù)據(jù)保存成功，并且不是很慢

錯誤如下：
