$.fn.serializeJson=function(){
            var serializeObj={};
            var array=this.serializeArray();
            var str=this.serialize();
            $(array).each(function(){
                if(serializeObj[this.name]){
                    if($.isArray(serializeObj[this.name])){
                        serializeObj[this.name].push(this.value);
                    }else{
                        serializeObj[this.name]=[serializeObj[this.name],this.value];
                    }
                }else{
                    serializeObj[this.name]=this.value;
                }
            });
            return serializeObj;
        };
