JSON 展示组件

基本用法

可以配置 value 展示 json 格式数据

{
    "type": "page",
    "body": {
        "type": "json",
        "value": {
            "a": "a",
            "b": "b",
            "c": {
                "d": "d"
            }
        }
    }
}

获取数据链值

也可以通过配置 source 获取数据链中的值

{
    "type": "page",
    "data":{
        "json":{
            "a": "a",
            "b": {
                "c": "c"
            }
        }
    },
    "body": {
        "type": "json",
        "source": "${json}"
    }
}

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",
                "json": {
                    "a": "a1",
                    "b": {
                        "c": "c1"
                    }
                }
            },
            {
                "id": "2",
                "json": {
                    "a": "a2",
                    "b": {
                        "c": "c2"
                    }
                }
            },
            {
                "id": "3",
                "json": {
                    "a": "a3",
                    "b": {
                        "c": "c3"
                    }
                }
            }
        ]
    },
    "columns": [
        {
            "name": "id",
            "label": "Id"
        },

        {
            "name": "json",
            "label": "颜色",
            "type": "json"
        }
    ]
}

List 的内容、Card 卡片的内容配置同上

Form 中静态展示

{
    "type": "form",
    "data": {
        "json": {
            "a": "a",
            "b": {
                "c": "c"
            }
        }
    },
    "body": [
        {
            "type": "control",
            "name": "json",
            "label": "Json",
            "body": {
                "type": "json"
            }
        }
    ]
}

主题

可配置jsonTheme，指定显示主题，可选twilight和eighties，默认为twilight。

[
{
    "type": "json",
    "value": {
        "a": "a",
        "b": "b",
        "c": {
            "d": "d"
        }
    }
},
{
    "type": "divider"
},
{
    "type": "json",
    "jsonTheme": "eighties",
    "value": {
        "a": "a",
        "b": "b",
        "c": {
            "d": "d"
        }
    }
}
]

配置默认展开层级

{
    "type": "page",
    "body": {
        "type": "json",
        "levelExpand": 0,
        "value": {
            "a": "a",
            "b": "b",
            "c": {
                "d": "d"
            }
        }
    }
}

如上，levelExpand配置为0，则默认不展开。

开启 json 修改

since 1.2.3

可配置mutable 为 true，展示 json 的同时支持修改。记得配置 name 属性。

[
{
    "type": "json",
    "name": "json",
    "mutable": true,
    "value": {
        "a": "a",
        "b": "b",
        "c": {
            "d": "d"
        }
    }
}
]

显示数据类型显示

还可以使用 displayDataTypes 开启数据类型显示

{
    "type": "page",
    "body": {
        "type": "json",
        "displayDataTypes":  true,
        "value": {
            "a": 1,
            "b": "b",
            "c": {
                "d": "d"
            }
        }
    }
}

文本过长自动处理

2.0.0 及以上版本

设置ellipsisThreshold可以设置字符串的最大展示长度，点击字符串可以切换全量/部分展示方式，默认展示全量字符串。

{
    "type": "page",
    "body": {
        "type": "json",
        "ellipsisThreshold": 80,
        "value": {
            "text": "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.",
        }
    }
}
