用来显示用户头像

基本使用

{
  "type": "avatar",
  "src": "https://suda.cdn.bcebos.com/images/amis/ai-fake-face.jpg"
}

文字

{
  "type": "avatar",
  "text": "AM"
}

图标

通过 icon 设置图标

{
  "type": "avatar",
  "icon": "fa fa-user"
}

如果同时存在 src、text 和 icon会优先用 src、接着 text、最后 icon

动态图片或文字

src、text 都支持变量,可以从上下文中动态获取图片或文字,下面的例子中第一个获取到了,而第二个没获取到,因此降级为显示 icon

{
  "data": {
    "myAvatar": "https://suda.cdn.bcebos.com/images/amis/ai-fake-face.jpg"
  },
  "type": "page",
  "body": [
    {
      "type": "avatar",
      "icon": "fa fa-user",
      "src": "$myAvatar"
    },
    {
      "type": "avatar",
      "icon": "fa fa-user",
      "src": "$other"
    }
  ]
}

方形和圆角形

可以通过 shape 改成方形或圆角形

[
  {
    "type": "avatar",
    "shape": "square",
    "text": "AM"
  },
  {
    "type": "avatar",
    "shape": "rounded",
    "text": "AM",
    "style": {
      "marginLeft": "10px"
    }
  }
]

大小

通过 size 可以控制头像的大小

[
  {
    "type": "avatar",
    "size": 20,
    "src": "https://suda.cdn.bcebos.com/images/amis/ai-fake-face.jpg"
  },
  {
    "type": "avatar",
    "size": 60,
    "src": "https://suda.cdn.bcebos.com/images/amis/ai-fake-face.jpg"
  }
]

图片拉伸方式

通过 fit 可以控制图片拉伸方式,默认是 cover,具体细节可以参考 MDN 文档

[
  {
    "type": "avatar",
    "fit": "cover",
    "src": "https://suda.cdn.bcebos.com/images/amis/plumeria.jpeg"
  },
  {
    "type": "avatar",
    "fit": "fill",
    "src": "https://suda.cdn.bcebos.com/images/amis/plumeria.jpeg"
  },
  {
    "type": "avatar",
    "fit": "contain",
    "src": "https://suda.cdn.bcebos.com/images/amis/plumeria.jpeg"
  },
  {
    "type": "avatar",
    "fit": "none",
    "src": "https://suda.cdn.bcebos.com/images/amis/plumeria.jpeg"
  },
    {
    "type": "avatar",
    "fit": "scale-down",
    "src": "https://suda.cdn.bcebos.com/images/amis/plumeria.jpeg"
  }
]

样式

可以通过 style 来控制背景及文字颜色

{
  "type": "avatar",
  "text": "AM",
  "style": {
    "background": "#DB3E35",
    "color": "#FFFFFF"
  }
}
