         }
         form.render('checkbox');
     });
     function init()
     {
         //多选初始化选中
         var checkboxJson = "22,23,24".split(',');//此处为从后台获取
         var obj = $('.fang_config_data');
         obj.map(function (index,value) {
             var v = $(value).val();
             if ($.inArray(v, checkboxJson) != -1) {

             }
         });
         //单选初始化选中
         var fang_status = "1";//此处为从后台获取，这里默认存储为1
         var bass_obj = $("input[name=fang_status][value='" + fang_status + "']").next('div');
         bass_obj.addClass('layui-form-radioed');
         bass_obj.children('i').addClass('layui-anim-scaleSpring');
