JS obtains multiple pieces of data in a form field and converts them into json format. Example sharing

This article mainly introduces the relevant information about JS obtaining multiple data in a form field and converting it into json format. Friends who need it can refer to it. I hope it can help everyone.

As shown in the figure, we need to obtain the data in the following two li tags and then pass them to the backend; and the data format received by the backend is json, so we need to get the data in the two li tags The information is converted into the following format.

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

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, '') //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") } })
