jQuery将form列表转JSON

function filedSelectJson(){
var a = {};
var reserveVenueCons = $("#orderForm").serializeArray();
var numreg = /\[[0-9]*\]\./;//正则表达式
var index = 0;
var attnum = 5;//list对象中有几个属性，这里有5个：reserveField.id，reserveField.name，orderPrice，startTime，endTime
var tmp = 0 ;
$.each(reserveVenueCons,function(n,v){
var name = v.name;
var names = name.split(numreg);//以 [0-9]. 为枢纽分割字符串
if(names.length > 1){//数组属性
if(!a[names[0]])//如果a[]没有属性names[0]
a[names[0]]= [];
if(!a[names[0]][index]) //如果a[names[0]]没有属性index
a[names[0]][index]= {};
a[names[0]][index][names[1]] = v.value;//设置
tmp++;
if((tmp)%attnum==0){
index++;
}
}else{//普通属性
a[v.name] = v.value;
}
});
var rtn=JSON.stringify(a);
return rtn;
}
