/**
 * 省市区3级联动使用说明：
 * 1.在页面的layui.use中装载模块  area
 * 2，定义调用变量 var area=layui.area;
 * 3.装载省数据 area.areaData("#province",1,"","");
 * 4.省联动装载市区：
 *  //装载市区数据
        form.on("select(province)",function(data){
            area.areaData("#city",2,data.value,"");
        });
 * 5.市联动装载区县
 //装载区县数据
        form.on("select(city)",function(data){
            area.areaData("#areas",3,data.value,"");
        });
具体使用见  system/hospital.html
