fastadmin中使用city-picker插件获取code值

在public里边的js文件（管理栏目所对应的js文件）中
添加

buildClassify:function(){
    //上一次选择的城市
    let prevCityCode='';
    //城市选择 获取行政code
    $("#city-picker").on("cp:updated", function() {

        var citypicker = $(this).data("citypicker");

        let province_code = citypicker.getCode("province");

        var city_code=citypicker.getCode("city");

        // let district_code=citypicker.getCode("district");

        $("#city_codes").val(province_code+","+city_code)

        // if(city_code != prevCityCode && typeof(city_code)!='undefined'){
        //     //请求数据
        //     Controller.api.hotelClassify(city_code);
        // }
    });

},

html文件中

<div class="form-group">
        <label class="control-label col-xs-12 col-sm-2">{:__('Province_id')}:</label>

        <div class='col-xs-12 col-sm-8'>
            <input id="city-picker" class="form-control" data-toggle="city-picker" data-responsive="true" data-level="city" placeholder="请选择省/市"  name="row[city]" type="text" value="" />
            <input type="hidden" id="city_codes" name="row[city_codes]" value="" />
        </div>

    </div>
