let thisContent = this;let loading = thisContent.$loading({ lock: true, text: '上传中,请稍候...', spinner: 'el-icon-loading', background: 'rgba(0, 0, 0, 0.5)' })// 中间进行一系列的操作// 上传成功后关闭loading, 并显示上传成功loading.close();thisC.$message('上传文件成功');
这样一个简单的loading效果就实现了。
请求的时候 需要一个全局loading来拦截 若是页面单独引用的话 就有点繁琐了 所以需要再全局封装一个 此时就要明白 再哪里封装了 先考虑一下 为什么要用
一方面是为了防止重复操作
另一方面是为了一个加载的效果能够更明显
所以 再请求的时候加 就能联想到axiOS拦截器的位置处理了 话不多说 开始撸代码 全程copy就行了
