//日期处理

    //js 日期格式化通用方法

            "m+" : this.getMinutes(), //minute

            "s+" : this.getSeconds(), //second

            "q+" : Math.floor((this.getMonth()+3)/3), //quarter

            "S" : this.getMilliseconds() //millisecond

            }

            if(/(y+)/.test(format)) {

                format = format.replace(RegExp.$1, (this.getFullYear()+"").substr(4 - RegExp.$1.length));

            }

            for(var k in o) {

              if(new RegExp("("+ k +")").test(format)) {

                  format = format.replace(RegExp.$1, RegExp.$1.length==1 ? o[k] : ("00"+ o[k]).substr((""+ o[k]).length));

              }

            }

            return format;

    }

     var now = new Date();

    // js 日期处理

    var nowadd = now.setFullYear(now.getFullYear()+2);

    var d2=new Date(nowadd)

    var nowStr = d2.format("yyyy-MM-dd");

    $('#userTime').val(nowStr);

//表单标准化成json

function standJsonByObj(obj){
