## 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 |

## 动作表

> 2.4.1 及以上版本

当前组件对外暴露以下特性动作，其他组件可以通过指定`actionType: 动作名称`、`componentId: 该组件id`来触发这些动作，动作配置可以通过`args: {动作配置项名称: xxx}`来配置具体的参数，详细请查看[事件动作](../../docs/concepts/event-action#触发其他组件的动作)。

| 动作名称 | 动作配置                 | 说明     |
| -------- | ------------------------ | -------- |
| clear    | -                        | 清空     |
| setValue | `value: string` 更新的值 | 更新数据 |
