el-upload loading

el-upload组件可以显示一个loading状态，用来表示文件上传的进度。根据引用和引用的代码片段，el-upload的loading状态可以通过设置`:loading`属性来控制。当`:loading`为true时，上传按钮会显示为加载中状态，表示文件正在上传。在上传过程中，可以通过设置`:on-progress`属性来监听上传进度，并在页面上显示上传进度条。当文件上传完成后，`:loading`属性会自动设置为false，loading状态会消失。所以，el-upload的loading状态会在文件上传过程中显示，上传完成后自动消失。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
