react项目使用了 Ant Design等需要三级联动的省市区资源库

let cityData = { "RECORDS": [ { "value": 110000, "label": "北京", "children": [{ "value": 110100, "label": "北京", "children": [{ "value": 110101, "label": "东城" }, { "value": 110102, "label": "西城" }, { "value": 110105, "label": "朝阳" }, { "value": 110106, "label": "丰台" }, { "value": 110107, "label": "石景山" }, { "value": 110108, "label": "海淀" }, { "value": 110109, "label": "门头沟" }, { "value": 110111, "label": "房山" }, { "value": 110112, "label": "通州" }, { "value": 110113, "label": "顺义" }, { "value": 110114, "label": "昌平" }, { "value": 110115, "label": "大兴" }, { "value": 110116, "label": "怀柔" }, { "value": 110117, "label": "平谷" }, { "value": 110228, "label": "密云" }, { "value": 110229, "label": "延庆" }] }] } Ant Design组件三级联动资源库必备
