卡片展示,不支持配置初始化接口初始化数据域,所以需要搭配类似像`Service`这样的,具有配置接口初始化数据域功能的组件,或者手动进行数据域初始化,然后通过`source`属性,获取数据链中的数据,完成数据展示。
## 基本用法
这里我们使用手动初始数据域的方式,即配置`data`属性,进行数据域的初始化。
```schema:height="450"
{
"type": "page",
"data": {
"items": [
{
"engine": "Trident",
"browser": "Internet Explorer 4.0",
"platform": "Win 95+",
"version": "4",
"grade": "X"
},
{
"engine": "Trident",
"browser": "Internet Explorer 5.0",
"platform": "Win 95+",
"version": "5",
"grade": "C"
},
{
"engine": "Trident",
"browser": "Internet Explorer 5.5",
"platform": "Win 95+",
"version": "5.5",
"grade": "A"
},
{
"engine": "Trident",
"browser": "Internet Explorer 6",
"platform": "Win 98+",
"version": "6",
"grade": "A"
},
{
"engine": "Trident",
"browser": "Internet Explorer 7",
"platform": "Win XP SP2+",
"version": "7",
"grade": "A"
}
]
},
"body": {
"type": "cards",
"source": "$items",
"card": {
"body": [
{
"label": "Engine",
"name": "engine"
},
{
"label": "Browser",
"name": "browser"
},
{
"name": "version",
"label": "Version"
}
],
"actions": [
{
"type": "button",
"level": "link",
"icon": "fa fa-eye",
"actionType": "dialog",
"dialog": {
"title": "查看详情",
"body": {
"type": "form",
"controls": [
{
"label": "Engine",
"name": "engine",
"type": "static"
},
{
"name": "browser",
"label": "Browser",
"type": "static"
},
{
"name": "version",
"label": "Version",
"type": "static"
}
]
}
}
}
]
}
}
}
```
或者你也可以使用 CRUD 的 [card 模式](./crud#cards-%E5%8D%A1%E7%89%87%E6%A8%A1%E5%BC%8F)
