|

|

## 基本用法
|
||||
|
||||
```schema: scope="body"
|
||||
{
|
||||
"type": "pdf-viewer",
|
||||
"id": "pdf-viewer",
|
||||
"src": "/examples/static/simple.pdf"
|
||||
}
|
||||
```
|
||||
|
||||
## 配合文件上传实现预览功能
|
||||
|
||||
配置和 `input-file` 相同的 `name` 即可
|
||||
|
||||
```schema: scope="body"
|
||||
{
|
||||
"type": "form",
|
||||
"title": "",
|
||||
"wrapWithPanel": false,
|
||||
"body": [
|
||||
{
|
||||
"type": "input-file",
|
||||
"name": "file",
|
||||
"label": "File",
|
||||
"asBlob": true,
|
||||
"accept": ".pdf"
|

{

"id": "pdf-viewer",
|
||||
"name": "file"
|
||||
}
|
