var house=$("#house-form").serializeJson();

var contract=$("#owner_contract").serializeJson();

var allocation=$("#house_allocation").serializeJson();

$.extend(param, house,contract,allocation);

serializeJson 是封装的拼接json的js方法:

$.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;  

    };
