本文实例为大家分享了jQuery实现简单三级联动的具体代码,供大家参考,具体内容如下
首先写一个JSON数据
[ { "province": "吉林省", "cities": [ { "city": "长春市", "counties": ["朝阳区", "经济开发区", "高新区"] }, { "city": "吉林市", "counties": ["东城区", "经济开发区", "老城区"] }, { "city": "白山市", "counties": ["二道区", "河东区", "高新区"] } ] }, { "province": "辽宁省", "cities": [ { "city": "沈阳市", "counties": ["朝阳区", "经济开发区", "高新区"] }, { "city": "大连市", "counties": ["东城区", "经济开发区", "老城区"] }, { "city": "铁岭市", "counties": ["二道区", "河东区", "高新区"] } ] }, { "province": "山东省", "cities": [ { "city": "青岛市", "counties": ["朝阳区", "经济开发区", "高新区"] }, { "city": "济南市", "counties": ["东城区", "经济开发区", "老城区"] }, { "city": "威海市", "counties": ["二道区", "河东区", "高新区"] } ] } ]
然后用Ajax动态获取JSON文件中的数据
