JS获取一个表单字段中多条数据并转化为json格式

{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
console.log(recieverMsg)
//{recieverName:小红,recieverPhone:12341234,recieverAddress:中国湖南},{recieverName:小明,recieverPhone:12345678,recieverAddress:中国上海}
 $.ajax({
 url: '',
 type: 'post',
 data: {
 receiverInfo:recieverMsg,//收件人信息
 },
 traditional:true,
 success: function(data){
 console.log(data);
 },
 error: function() {
 alert("新增订单失败")
 }
 })
