## 基本用法
```schema:height="300" scope="body"
{
"type": "tabs",
"tabs": [
{
"title": "Tab 1",
"tab": "Content 1"
},
{
"title": "Tab 2",
"tab": "Content 2"
}
]
}
```
## 展示模式
### 线型
```schema:height="300" scope="body"
{
"type": "tabs",
"mode": "line",
"tabs": [
{
"title": "选项卡1",
"body": "选项卡内容1"
},
{
"title": "选项卡2",
"body": "选项卡内容2"
},
{
"title": "选项卡3",
"body": "选项卡内容3"
}
]
}
```
### 卡片模式
```schema:height="300" scope="body"
{
"type": "tabs",
"mode": "card",
"tabs": [
{
"title": "选项卡1",
"body": "选项卡内容1"
},
{
"title": "选项卡2",
"body": "选项卡内容2"
},
{
"title": "选项卡3",
"body": "选项卡内容3"
}
]
}
```
### 选择器型
```schema:height="300" scope="body"
{
"type": "tabs",
"mode": "radio",
"tabs": [
{
"title": "选项卡1",
"body": "选项卡内容1"
},
{
"title": "选项卡2",
"body": "选项卡内容2"
},
{
"title": "选项卡3",
"body": "选项卡内容3"
}
]
}
```
## 配置顶部工具栏
配置`toolbar`实现顶部工具栏。
```schema:height="200" scope="body"
{
"type": "tabs",
"toolbar": [
{
"type": "button",
"label": "按钮",
"actionType": "dialog",
"dialog": {
"title": "弹窗标题",
"body": "你点击了"
}
}
],
"tabs": [
{
"title": "Tab 1",
"tab": "Content 1"
},
{
"title": "Tab 2",
"tab": "Content 2"
}
]
}
```
## 配置 hash
可以在单个`tab`下,配置`hash`属性,支持地址栏`#xxx`。
```schema:height="300" scope="body"
{
"type": "tabs",
"tabs": [
{
"title": "Tab 1",
"hash": "tab1",
"tab": "Content 1"
},
{
"title": "Tab 2",
"hash": "tab2",
"tab": "Content 2"
}
]
}
```
## 默认显示某个选项卡
主要配置`activeKey`属性来实现该效果,共有下面两种方法:
#### 配置 hash 值
```schema:height="300" scope="body"
{
"type": "tabs",
"activeKey": "tab2",
"tabs": [
{
"title": "Tab 1",
"hash": "tab1",
"tab": "Content 1"
},
{
"title": "Tab 2",
"hash": "tab2",
"tab": "Content 2"
}
]
}
```
#### 配置索引值
单个`tab`上不要配置`hash`属性,配置需要展示的`tab`索引值,`0`代表第一个。
```schema:height="300" scope="body"
{
"type": "tabs",
"activeKey": 1,
"tabs": [
{
"title": "Tab 1",
"tab": "Content 1"
},
{
"title": "Tab 2",
"tab": "Content 2"
}
]
}
```
## unmountOnExit
如果你想在切换 tab 时,自动销毁掉隐藏的 tab请配置`"unmountOnExit": true`
