基本用法

{
    "type": "page",
    "body": {
        "type": "mapping",
        "value": "1",
        "map": {
            "1": "第一",
            "2": "第二",
            "3": "第三",
            "*": "其他"
        }
    }
}

渲染 HTML

{
    "type": "page",
    "body": {
        "type": "mapping",
        "value": "2",
        "map": {
            "1": "<span class='label label-info'>漂亮</span>",
            "2": "<span class='label label-success'>开心</span>",
            "3": "<span class='label label-danger'>惊吓</span>",
            "4": "<span class='label label-warning'>紧张</span>",
            "*": "<span class='label label-default'>其他:${type}</span>"
        }
    }
}

用作 Field 时

当用在 Table 的列配置 Column、List 的内容、Card 卡片的内容和表单的 Static-XXX 中时,可以设置name属性,映射同名变量

Table 中的列类型

{
    "type": "table",
    "data": {
        "items": [
            {
                "id": "1",
                "type": "1"
            },
            {
                "id": "2",
                "type": "2"
            },
            {
                "id": "3",
                "type": "3"
            }
        ]
    },
    "columns": [
        {
            "name": "id",
            "label": "Id"
        },

        {
            "name": "type",
            "label": "映射",
            "type": "mapping",
            "map": {
                "1": "<span class='label label-info'>漂亮</span>",
                "2": "<span class='label label-success'>开心</span>",
                "3": "<span class='label label-danger'>惊吓</span>",
                "4": "<span class='label label-warning'>紧张</span>",
                "*": "其他:${type}"
            }
        }
    ]
}

List 的内容、Card 卡片的内容配置同上

Form 中静态展示

{
    "type": "form",
    "data": {
        "type": "2"
    },
    "controls": [
        {
            "type": "static-mapping",
            "name": "type",
            "label": "映射",
            "map": {
                "1": "<span class='label label-info'>漂亮</span>",
                "2": "<span class='label label-success'>开心</span>",
                "3": "<span class='label label-danger'>惊吓</span>",
                "4": "<span class='label label-warning'>紧张</span>",
                "*": "其他:${type}"
            }
        }
    ]
}

布尔值映射

{
    "type": "form",
    "data": {
        "type": true
    },
    "controls": [
        {
            "type": "static-mapping",
            "name": "type",
            "label": "映射",
            "map": {
                "1": "<span class='label label-info'>开</span>",
                "0": "<span class='label label-default'>关</span>"
            }
        }
    ]
}

或者

{
    "type": "form",
    "data": {
        "type": true
    },
    "controls": [
        {
            "type": "static-mapping",
            "name": "type",
            "label": "映射",
            "map": {
                "true": "<span class='label label-info'>开</span>",
                "false": "<span class='label label-default'>关</span>"
            }
        }
    ]
}

远程拉取字典

since 1.1.6

通过配置 source 接口来实现,接口返回字典对象即可,数据格式参考 map 配置。

{
    "type": "form",
    "data": {
        "type": "2"
    },
    "controls": [
        {
            "type": "mapping",
            "name": "type",
            "label": "映射",
            "source": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mapping"
        }
    ]
}

默认 source 是有 30s 缓存的,通常字典数据不长变更。如果想修改,请参考 API 文档配置缓存。

关联上下文变量

since 1.1.6

同样通过配置 source 来实现,只是格式是取变量。

{
    "type": "form",
    "initApi": {
        "url": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mapping",
        "method": "get",
        "responseData": {
            "zidian": "$$$$",
            "type": "2"
        }
    },
    "controls": [
        {
            "type": "mapping",
            "name": "type",
            "label": "映射",
            "source": "$${zidian}"
        }
    ]
}

属性表

属性名 类型 默认值 说明
type string 如果在 Table、Card 和 List 中,为"color";在 Form 中用作静态展示,为"static-color"
className string 外层 CSS 类名
placeholder string 占位文本
map object 映射配置
source string or API API数据映射
