JS遍历表单列表并转换为JSON格式提交

{recieverName:小红,recieverPhone:12341234,recieverAddress:中国湖南},{recieverName:小明,recieverPhone:12345678,recieverAddress:中国上海}

var recieverArr = []; //全局变量
var recieverMsg = {}; //全局变量
function recieverMsgToJson(parentFormId){  //若有多个表单公用这个函数，这里需要传所属表单的ID；例如新增和修改。
 $(parentFormId + ".recieverList li").each(function(m){  //遍历每个li，当前有两个li
   var recieverAttributes = [];
   $(this).find("span").each(function(n){  //遍历每个li下的span，而每个li下有三个span
     recieverAttributes[n] = $(this).children("input").val();  //找到每个span下存放着数据的input框，并获取值存放到数组中
   });
   var recieverObj = {  //用对象来表示数据；这时对象是{recieverName:小明,recieverPhone:12345678,recieverAddress:中国上海}
     receiverName:recieverAttributes[0],
     receiverPhone:recieverAttributes[1],
     receiverAddress:recieverAttributes[2]
   };
   recieverArr.push(recieverObj);    
 });
}
recieverMsg = JSON.stringify(recieverArr).replace(/\[|]/g, '') //将数组转化为json格式
