基本用法

{
    "type": "carousel",
    "auto": false,
    "thumbMode": "cover",
    "animation": "slide",
    "height": 300,
    "options": [
        {
            "image": "https://internal-amis-res.cdn.bcebos.com/images/2019-12/1577157239810/da6376bf988c.png"
        },
        {
            "html": "<div style=\"width: 100%; height: 300px; background: #e3e3e3; text-align: center; line-height: 300px;\">carousel data</div>"
        },
        {
            "thumbMode": "contain",
            "image": "https://suda.cdn.bcebos.com/amis/images/alice-macaw.jpg"
        }
    ]
}

动态列表

轮播图组件目前没有获取数据的配置,因此需要依赖 service 来获取数据。

{
  "type": "page",
  "body": {
    "type": "service",
    "api": "/api/mock2/options/carousel",
    "body": {
      "type": "carousel",
      "name": "imageList"
    }
  }
}

目前数据关联是通过 name 的方式,因此 api 返回应该是类似这样的:

{
    status: 0,
    msg: '',
    data: {
        imageList: [{
            "image": "https://internal-amis-res.cdn.bcebos.com/images/2019-12/1577157239810/da6376bf988c.png"
        }]
    }
}

其中的 imageList 要和配置的 name 值对应。

点击图片打开外部链接

1.3.3 及以上版本

需要放回的字段中除了前面的 image还有 href 属性

{
  "type": "page",
  "data": {
    "imageList": [
      {
        "image": "https://internal-amis-res.cdn.bcebos.com/images/2019-12/1577157239810/da6376bf988c.png",
        "href": "https://github.com/baidu/amis"
      }
    ]
  },
  "body": {
    "type": "carousel",
    "name": "imageList"
  }
}

自定义轮播图的展现

通过配置 itemSchema 可以自定义轮播图的展现,比如图片默认背景配置是 contain可以改成 cover

itemSchema: {
    type: 'tpl',
    tpl: '<div style="background-image: url("${image}"); background-size: cover; background-repeat: no-repeat; background-position: center center;" class="image ${imageClassName}"></div>'
}

多图展示

    "animation": "slide",
    "multiple": {count: 3},
    "interval": 1000,
    "duration": 5000,

事件表

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${事件参数名}${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

事件名称 事件参数 说明
change activeIndex: number 激活图片的索引
prevIndex: number 上一张图片的索引
轮播图切换时触发

change

{
  "type": "carousel",
  "auto": false,

动作表

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

动作名称 动作配置 说明
next - 下一张
prev - 上一张
