基本用法

{
  "type": "breadcrumb",
  "items": [
    {
      "label": "首页",
      "href": "https://baidu.gitee.com/",
      "icon": "fa fa-home"
    },

    {
      "label": "上级页面"
    },

    {
      "label": "当前页面"
    }
  ]
}

动态数据

可以配置 source 来获取上下文中的动态数据，结合 service 来实现动态生成。

{
  "type": "page",
  "data": {
    "breadcrumb": [
      {
        "label": "首页",
        "href": "https://baidu.gitee.com/"
      },

      {
        "label": "上级页面"
      },

      {
        "label": "当前页面"
      }
    ]
  },
  "body": {
    "type": "breadcrumb",
    "source": "${breadcrumb}"
  }
}

分隔符

{
  "type": "breadcrumb",
  "separator": ">",
  "separatorClassName": "text-black",
  "items": [
    {
      "href": "https://baidu.gitee.com/",
      "icon": "fa fa-home"
    },

    {
      "label": "上级页面"
    },

    {
      "label": "当前页面"
    }
  ]
}

下拉菜单

{
  "type": "breadcrumb",
  "separator": ">",
  "separatorClassName": "text-black",
  "items": [
    {
      "label": "首页",
      "href": "https://baidu.gitee.com/",
      "icon": "fa fa-home"
    },

    {
      "label": "上级页面",
      "dropdown": [
        {
          "label": "选项一",
          "href": "https://baidu.gitee.com/",
        },
        {
          "label": "选项二"
        }
      ]
    },
    {
      "label": "当前页面"
    }
  ]
}

最大展示长度

{
  "type": "breadcrumb",
  "separator": ">",
  "separatorClassName": "text-black",
  "labelMaxLength": 16,
  "tooltipPosition": "top",
  "items": [
    {
      "href": "https://baidu.gitee.com/",
      "icon": "fa fa-home"
    },

    {
      "label": "上级页面上级页面上级页面上级页面上级页面"
    },

    {
      "label": "当前页面"
    }
  ]
}
