> 当然,`crud`组件内置已经支持此功能,你只需要配置`crud`中的`filter`属性,就可以实现上面的效果,更多内容查看 [crud -> filter](../components/crud) 文档。
我们再来一个例子,这次我们实现两个`form`之间的联动:
我们再来一个例子,这次我们实现 [两个 form 之间的联动](../components/form/index#%E5%B0%86%E6%95%B0%E6%8D%AE%E5%9F%9F%E5%8F%91%E9%80%81%E7%BB%99%E7%9B%AE%E6%A0%87%E7%BB%84%E4%BB%B6)
### 发送指定数据
`target`属性支持通过配置参数来发送指定数据,例如:`"target" :"xxx?a=${a}&b=${b}"`,这样就会把当前数据域中的`a`变量和`b`变量发送给目标组件
```schema:height="800" scope="body"
[
{
"type": "form",
"title": "form1",
"mode": "horizontal",
"api": "/api/mock2/form/saveForm",
"controls": [
{
"label": "Name",
"type": "text",
"name": "name"
},
{
"label": "Email",
"type": "text",
"name": "email"
},
{
"label": "Company",
"type": "text",
"name": "company"
}
],
"actions": [
{
"type": "action",
"actionType": "reload",
"label": "发送到 form2",
"target": "form2?name=${name}&email=${email}"
}
]
},
{
"type": "form",
"title": "form2",
"name": "form2",
"mode": "horizontal",
"api": "/api/mock2/form/saveForm",
"controls": [
{
"label": "MyName",
"type": "text",
"name": "name"
},
{
"label": "MyEmail",
"type": "text",
"name": "email"
},
{
"label": "Company",
"type": "text",
"name": "company"
}
]
}
]
```
上例中我们给按钮上配置了`"target": "form2?name=${name}&email=${email}"`,可以把当前数据链中的`name`变量和`email`变量发送给`form2`
### 配置多个目标
`target`支持配置多个目标组件 name用逗号隔开例如
```json
{
"type": "action",
"actionType": "reload",
"label": "刷新目标组件",
"target": "target1,target2"
}
```
上例中点击按钮会刷新`target1`和`target2`组件。
事实上,**组件间联动也可以实现上述任意的 [基本联动效果](./linkage#%E5%9F%BA%E6%9C%AC%E8%81%94%E5%8A%A8)(显隐联动、接口联动等其他联动)。**
