Element upload组件的onChange传递多个参数

:on-change=“handleChange”
把handleChange改变为箭头函数 ()=>{} 接收到参数后接着再携带再调用即可

:on-change=“(file, fileList) => {filehandleChange(file, fileList, item)}”

const filehandleChange = (file, fileList, item) => {
  console.log(file, fileList, item);
  if (!fileFlag) {
    fileFlag = setTimeout(() => {
      emit("Get" + item.File, file, fileList, item);
      clearTimeout(fileFlag);
      fileFlag = null;
    }, 50);
  }
};
