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 ='<div class="picture" style="width:108px;float:left;"><img id="preview" src="'+后台返回的tu'pian路径+'" 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></div>';            $("#refund_img").after(img_tpl);          }        },        error: function(err) {        alert("网络错误");        }      });} }
