As shown in the figure, we need to obtain the data in the following two li tags and then pass it to the backend; the data format received by the backend is json, so we need to convert the information in the two li In the following format.

{recieverName:Xiaohong,recieverPhone:12341234,recieverAddress:Hunan,China},{recieverName:Xiaoming,recieverPhone:12345678,recieverAddress:Shanghai, China}

The code is as follows:

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, &#39;&#39;) //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: &#39;&#39;,
    type: &#39;post&#39;,
    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")
    }
  })
