门户栏目组件。
## 基本用法
```schema: scope="body"
{
"type": "page",
"data": {
"text": "这是一段描述信息"
},
"body": {
"type": "portlet",
"description": "${text}",
"tabs": [
{
"title": "标题",
"tab": "Content 1"
},
{
"title": "标题2",
"tab": "Content 2"
}
]
}
}
```
## 配置工具栏
```schema: scope="body"
{
"type": "portlet",
"toolbar": [
{
"label": "固定操作",
"type": "button",
"actionType": "ajax",
"api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm"
}
],
"tabs": [
{
"title": "Tab 1",
"tab": "Content 1",
"toolbar": [
{
"label": "ajax请求",
"type": "button",
"actionType": "ajax",
"api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm"
},
{
"type": "dropdown-button",
"level": "link",
"icon": "fa fa-ellipsis-h",
"hideCaret": true,
"buttons": [
{
"type": "button",
"label": "编辑",
"actionType": "dialog",
"dialog": {
"title": "编辑",
"body": "你正在编辑该卡片"
}
},
{
"type": "button",
"label": "删除",
"actionType": "dialog",
"dialog": {
"title": "提示",
"body": "你删掉了该卡片"
}
}
]
}
]
},
{
"title": "Tab 2",
"tab": "Content 2",
"toolbar": [
{
"type": "button",
"level": "link",
"url": "https://www.baidu.com",
"actionType": "url",
"size": "sm",
"label": "跳转2"
}
]
}
]
}
```
## 隐藏头部
去掉头部,默认只展示内容 tab 第一项的内容
```schema: scope="body"
{
"type": "portlet",
"hideHeader": true,
"tabs": [
{
"title": "Tab 1",
"tab": "Content 1"
}
]
}
```
## 设置 style
默认 tabs 只有一项的时候没有选中状态
```schema: scope="body"
{
"type": "portlet",
"style": {
"borderColor": '#333'
},
"tabs": [
{
"title": "Tab 1",
"tab": "Content 1"
}
]
}
```
## 去掉分隔线
```schema: scope="body"
{
"type": "portlet",
"divider": false,
"tabs": [
{
"title": "标题",
"tab": "Content 1"
}
]
}
```
## source 动态数据
配置 source 属性,根据某个数据来动态生成。具体使用参考 Tabs 选项卡组件
## 图标
通过 icon 可以设置 tab 的图标,可以是 fontawesome 或 URL 地址。
```schema: scope="body"
{
"type": "portlet",
"tabs": [
{
"title": "Tab 1",
"tab": "Content 1",
"icon": "https://suda.cdn.bcebos.com/images%2F2021-01%2Fdiamond.svg"
},
{
"title": "Tab 2",
"tab": "Content 2"
}
]
}
```
## mountOnEnter
只有在点击卡片的时候才会渲染,在内容较多的时候可以提升性能,但第一次点击的时候会有卡顿。
## unmountOnExit
如果你想在切换 tab 时,自动销毁掉隐藏的 tab请配置`"unmountOnExit": true`。
## 监听切换事件
```schema: scope="body"
{
"type": "portlet",
"activeKey": 1,
"onSelect": "alert(key)",
"tabs": [
{
"title": "Tab 1",
"tab": "Content 1"
},
{
"title": "Tab 2",
"tab": "Content 2"
}
]
}
```
会传递 key 参数和 props
