AJAX地区三级联动JSON指的是通过AJAX技术获取JSON数据来实现省市区三级联动选择功能。
使用AJAX技术,可以在不刷新页面的情况下实现地区选择的动态变化。以获取省市区JSON数据为例,以下是一份示例代码:
{ "province": [ { "name": "北京","city": [ { "name": "北京市","district": [ "东城区","西城区","朝阳区","丰台区","石景山区","海淀区","门头沟区","房山区","通州区","顺义区","昌平区","大兴区","怀柔区","平谷区","密云区","延庆区" ] } ] },{ "name": "上海","city": [ { "name": "上海市","district": [ "黄浦区","徐汇区","长宁区","静安区","普陀区","虹口区","杨浦区","闵行区","宝山区","嘉定区","浦东新区","金山区","松江区","青浦区","奉贤区","崇明区" ] } ] },... ] }
通过以上JSON数据,在页面中实现地区选择可以采用以下方式:
