ant design中upload组件上传大文件,显示进度条进度的实例
您好,关于您的问题,可以通过监听 upload 组件的 onChange 事件,获取上传进度值并显示在页面中,从而实现上传进度条的效果。以下是示例代码:
```
<template>
<div>
<a-upload
:action="uploadUrl"
:show-upload-list="false"
:before-upload="beforeUpload"
:on-progress="onUploadProgress"
>
<a-button>上传文件</a-button>
</a-upload>
<a-progress :percent="uploadPercent" />
</div>
</template>
<script>
import { ref } from 'vue';
import { message } from 'ant-design-vue';
export default {
setup() {
const uploadUrl = 'your upload url'; // 上传接口地址
const uploadPercent = ref(0); // 初始化上传进度为0
// 上传前的操作
const beforeUpload = (file) => {
// 可以在此处对上传的文件进行校验等操作
};
// 上传进度变化时的操作
const onUploadProgress = (progressEvent) => {
if (progressEvent.total > 0) {
uploadPercent.value = Math.round((progressEvent.loaded / progressEvent.total) * 100); // 计算上传进度
}
};
return {
uploadUrl,
uploadPercent,
beforeUpload,
onUploadProgress,
};
},
};
</script>
```
希望可以帮到您!
