## 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:${&|json}</p>"
}
]
}
```
## 禁用样式
> `6.0.0`及以上版本
```schema
{
"type": "page",
"initApi": "/api/mock2/page/initData?keywords=${keywords}",
"body": [
{
"type": "flex",
"direction": "column",
"justify": "flex-start",
"alignItems": "flex-start",
"items": [
{
"type": "search-box",
"name": "keywords",
"disabled": true,
"style": {
"marginBottom": "10px"
}
},
{
"type": "search-box",
"name": "keywords",
"mini": true,
"disabled": true
}
]
}
]
}
```
## 加载状态
> `6.0.0` 及以上版本
设置`"loading": true`, 标识开关操作的异步任务仍在执行中。另外`loadingOn`支持表达式,配合`ajax`动作实现搜索操作时的loading状态。
```schema
{
"type": "page",
"id": "demo-page",
"data": {
"isFetching": false,
"fetched": false
},
"body": [
{
"type": "search-box",
"name": "keywords",
"clearable": true,
"loadingOn": "${isFetching}",
"className": "mb-2",
"onEvent": {
"search": {
"actions": [
{
"actionType": "setValue",
"componentId": "demo-page",
"args": {
"value": {
"isFetching": true
}
}
},
{
"actionType": "toast",
"args": {
"msgType": "warning",
"msg": "开始检索..."
}
},
{
"actionType": "ajax",
"api": {
"url": "/api/mock2/sample?perPage=5&waitSeconds=2&keywords=${keywords}",
"method": "get",
"messages": {
"success": "检索完成",
"failed": "检索失败"
}
}
},
{
"actionType": "setValue",
"componentId": "demo-page",
"args": {
"value": {
"isFetching": false,
"fetched": true,
"total": "${event.data.responseResult.count}",
"datasource": "${event.data.responseResult.rows}"
}
}
}
]
}
}
},
{
"type": "flex",
"visibleOn": "${fetched && !isFetching}",
"justify": "flex-start",
"alignItems": "flex-start",
"direction": "column",
"items": [
{
"type": "flex",
"className": "mb-2",
"alignItems": "self-end",
"items": [
{
"type": "status",
"value": "success",
"className": "mr-2",
"labelMap": {
"success": "检索成功:"
}
},
{
"type": "tpl",
"tpl": "总计${total}条当前仅展示5条"
},
]
},
{
"type": "list",
"source": "${datasource}",
"listItem": {
"body": [
{
"type": "hbox",
"columns": [
{
"label": "Engine",
"name": "engine"
},
{
"name": "version",
"label": "Version"
}
]
}
]
}
}
]
}
]
}
```
## 加强样式
```schema
{
"type": "page",
"initApi": "/api/mock2/page/initData?keywords=${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:${&|json}</p>"
}
]
}
```
### 清除后立即搜索
> `2.8.0` 及以上版本
设置`"clearAndSubmit": true`后,清空搜索框内容后立即执行搜索,与`searchImediately`不同的是,`clearAndSubmit`仅作用于清空输入框的动作,而`searchImediately`会影响所有搜索动作。
```schema
{
"type": "page",
"initApi": "/api/mock2/page/initData?keywords=${keywords}",
"body": [
{
"type": "search-box",
"name": "keywords",
"clearable": true,
"clearAndSubmit": 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:${&|json}</p>"
}
]
}
```
## 与 CRUD 搭配
```schema: scope="body"
{
"type": "crud",
"api": "/api/mock2/sample",
"syncLocation": false,
"headerToolbar": [
{
"type": "search-box",
"name": "keywords",
"align": "right",
"placeholder": "关键字检索"
}
],
"columns": [
{
"name": "id",
"label": "ID"
},
{
"name": "engine",
"label": "Rendering engine"
},
{
"name": "browser",
"label": "Browser"
},
{
"name": "platform",
"label": "Platform(s)"
},
{
"name": "version",
"label": "Engine version"
},
{
"name": "grade",
"label": "CSS grade"
}
]
}
```
## 与 Service 搭配
```schema
{
"type": "page",
"body": [
{
"type": "service",
"api": "/api/mock2/page/initData?keywords=${keywords}",
"body": [
{
"type": "search-box",
"name": "keywords"
},
{
"type": "tpl",
"tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
}
]
}
]
}
```
## 立刻搜索模式
设置 `"searchImediately": true` 实现输入时即搜索
```schema
{
"type": "page",
"body": [
{
"type": "service",
"api": "/api/mock2/page/initData?keywords=${keywords}",
"body": [
{
"type": "search-box",
"name": "keywords",
"searchImediately": true
},
{
"type": "tpl",
"tpl": "<p>关键字:${keywords}</p><p>返回结果:${&|json}</p>"
}
]
}
]
}
```

## 事件表
> 2.4.1 及以上版本
当前组件会对外派发以下事件,可以通过`onEvent`来监听这些事件,并通过`actions`来配置执行的动作,在`actions`中可以通过`${事件参数名}`或`${event.data.[事件参数名]}`来获取事件产生的数据,详细请查看[事件动作](../../docs/concepts/event-action)。
> `[name]`表示当前组件绑定的名称,即`name`属性,如果没有配置`name`属性,则通过`value`取值。
| 事件名称 | 事件参数 | 说明 |
| -------- | ------------------------- | -------------------- |
| search | `[name]: string` 组件的值 | 点击搜索图标时触发 |
| change | `[name]: string` 组件的值 | 输入框值变化时触发 |
| focus | `[name]: string` 组件的值 | 输入框获取焦点时触发 |
| blur | `[name]: string` 组件的值 | 输入框失去焦点时触发 |
