## 基本用法
|
|
|
|
用于展示一个简单搜索框,通常需要搭配其他组件使用。比如 page 配置 `initApi` 后,可以用来实现简单数据过滤查找,`name` keywords 会作为参数传递给 page 的 `initApi`。
|
|
|
|
```schema
|
|
{
|
|
"type": "page",
|
|
"initApi": "/api/mock2/page/initData?keywords=${keywords}",
|
|
"body": [
|
|
{
|
|
"type": "search-box",
|
|
"name": "keywords"
|
|
},
|
|
|
|
{
|
|
"type": "tpl",
|
|
"tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## 加强样式
|
|
|
|
```schema
|
|
{
|
|
"type": "page",
|
|
"initApi": "/api/mock2/page/initData?keywords=${keywords}",
|
|
"body": [
|
|
{
|
|
"type": "search-box",
|
|
"name": "keywords",
|
|
"enhance": true
|
|
},
|
|
|
|
{
|
|
"type": "tpl",
|
|
"tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## 可清除
|
|
|
|
```schema
|
|
{
|
|
"type": "page",
|
|
"initApi": "/api/mock2/page/initData?keywords=${keywords}",
|
|
"body": [
|
|
{
|
|
"type": "search-box",
|
|
"name": "keywords",
|
|
"clearable": true
|
|
},
|
|
|
|
{
|
|
"type": "tpl",
|
|
"tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## mini 版本
|
|
|
|
```schema
|
|
{
|
|
"type": "page",
|
|
"initApi": "/api/mock2/page/initData?keywords=${keywords}",
|
|
"body": [
|
|
{
|
|
"type": "search-box",
|
|
"name": "keywords",
|
|
"mini": true
|
|
},
|
|
|
|
{
|
|
"type": "tpl",
|
|
"tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
|
|
}
|
|
