Sample code to implement image and file upload in vue

Below I will share with you a sample code for uploading images and files in vue. It has a good reference value and I hope it will be helpful to everyone.

html page

<input type="file" value="" id="file" @change=&#39;onUpload&#39;>//注意不能带括号

js code

methods: {
//上传图片
onUpload(e){
      var formData = new FormData(); 
    f ormData.append('file', e.target.files[0]);
    formData.append('type', 'test');
      $.ajax({
        url: '/ShopApi/util/upload.weixun'，//这里是后台接口需要换掉
        type: 'POST',
        dataType: 'json',
        cache: false,
        data: formData,
        processData: false,
        contentType: false,
        success: (res) => {        
          if (res.code === 200) {
            var img_tpl =&#39;<p class="picture" style="width:108px;float:left;"><img id="preview" src="&#39;+后台返回的tu&#39;pian路径+&#39;" style="width:48px;height:48px;float:left;background-size:cover;"/><span class="r-span"
 onclick = "onDeletePicture()" style="color:#49BDCC;display:block;float:left;margin-left:10px;line-height:48px;">删除</span></p>&#39;;
            $("#refund_img").after(img_tpl);
          }
        },
        error: function(err) {
        alert("网络错误");
        }
      });
} 
}
