步骤条组件

## 基本用法

```schema
{
  "type": "page",
  "body": [
    {
      "type": "steps",
      "value": 1,
      "steps": [
        {
          "title": "First",
          "subTitle": "this is subTitle",
          "description": "this is description"
        },
        {
          "title": "Second"
        },
        {
          "title": "Last"
        }
      ]
    }
  ]
}
```

## 设置状态

```schema
{
  "type": "page",
  "body": {
    "type": "steps",
    "value": 1,
    "status": "error",
    "steps": [
      {
        "title": "First"
      },
      {
        "title": "Second",
        "subTitle": "this is subTitle",
        "description": "this is description"
      },
      {
        "title": "Last"
      }
    ]
  }
}
```

## 数据映射

```schema
{
  "type": "page",
  "data": {
    "step": 1,
    "status": "error",
    "secondTitle": "Second"
  },
  "body": [
    {
      "type": "steps",
      "status": "${status}",
      "value": "${step}",
      "steps": [
        {
          "title": "First",
          "subTitle": "this is subTitle",
          "description": "this is description"
        },
        {
          "title": "${secondTitle}"
        },
        {
          "title": "Last"
        }
      ]
    }
  ]
}
```

## 接口映射

```schema
{
  "type": "page",
  "initApi": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/steps/get",
  "body": [
    {
      "type": "steps",
      "value": "${step}",
      "status": "${status}",
      "steps": [
        {
          "title": "First",
          "subTitle": "this is subTitle",
          "description": "this is description"
        },
        {
          "title": "Secord"
        },
        {
          "title": "Last"
        }
      ]
    }
  ]
}
```

## Form 中静态展示

```schema
{
  "type": "page",
  "body": {
    "type": "form",
    "initApi": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/steps/steps",
    "controls": [
      {
        "type": "steps",
        "source": "${steps}",
        "value": "${current}"
      }
    ]
  }
}
```

## 远程拉取

除了可以通过数据映射获取当前数据域中的变量以外，source 还支持配置接口，格式为 API，用于动态返回选项组。

```schema
{
  "type": "page",
  "body": {
    "type": "form",
    "controls": [
      {
        "type": "steps",
        "name": "steps",
        "source": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/steps/steps"
      }
    ]
  }
}
```

远程拉取接口时，返回的数据结构除了需要满足 amis 接口要求的基本数据结构 以外，必须用"steps"作为选项组的 key 值，如下：

```json
{
  "status": 0,
  "msg": "",
  "data": {
    "steps": [
      {
        "title": "First",
        "subTitle": "this is sub title",
        "value": "first"
      },
      {
        "title": "Secord",
        "description": "this is description",
        "value": "secord"
      },
      {
        "title": "Last",
        "value": "last"
      }
    ]
  }
}
```

## 自定义不同步骤以及状态

```schema
{
  "type": "page",
  "body": {
    "type": "steps",
    "value": "b",
    "status": {
      "a": "finish",
      "b": "error",
      "c": "wait"
    },
    "steps": [
      {
        "title": "First",
        "value": "a"
      },
      {
        "title": "Second",
        "subTitle": "this is subTitle",
        "description": "this is description",
        "value": "b"
      },
      {
        "title": "Third",
        "value": "c"
      }
    ]
  }
}
```
