@ -240,6 +240,39 @@ Word 渲染支持以下功能:
注意上面的例子用到了 `trackExpression`,默认情况下如果设置了 `enableVar`,每次上层数据变化都会重新渲染文档,如果文档较大可能会有性能问题,这时可以通过配置 `trackExpression` 来限制只有某个数据变化时才重新渲染。
### 图片中的变量
> 2.10 及以上版本
如果要将文档中的图片设置为变量,需要右键对应的图片,选择「查看可选文字」,然后填入类似 `{{img}}` 变量标识,在渲染时图片将替换为这个 `img` 变量的 url 地址

```schema: scope="body"
{
"type": "form",
"title": "",
"wrapWithPanel": false,
"body": [
{
"type": "input-text",
"name": "img",
"value": "https://suda.cdn.bcebos.com/images/amis/ai-fake-face.jpg",
"label": "图片地址"
},
{
"type": "office-viewer",
"id": "office-viewer",
"src": "/examples/static/image-alt-var.docx",
"wordOptions": {
"enableVar": true,
"padding": "8px"
}
}
]
}
```
## 不渲染模式
通过配置 `display: false` 可以让文档不渲染,虽然不渲染,但还是可以使用后面的下载及打印功能
