这是我的JSFiddle：https://jsfiddle.net/inchrvndr/7pwh9p8g/
The bordered form elements get cloned on click of "+" button.
除了正在进行克隆的父级之外，所有克隆表单元素的值都将传递到JSON。
单击“保存”按钮，您可以看到除第一个边界div之外的所有表单字段值的JSON对象警报。
为什么会这样？请帮忙。 谢谢:)）

试试这个..
更新：
你有重复的元素，比如这个：id="op"页面上只能有一个唯一的ID ..我建议你删除id或生成它们
$( document ).ready(function() {
$('#deleteRow').closest('.form-group').hide();
$('#addRow').on('click', function (e) {
var len = $('.child-border').length;
$('.parent-border-repeat').clone().find(':input').each(function (idx, ele) {
ele.name = ele.name + len;
ele.id = ele.id + len;
ele.value = '';
}).end().find('.form-group').toggle(true).end()
.toggleClass('parent-border-repeat child-border').hide()
.appendTo('#container').slideDown('slow');
});
$('button.btn:contains("Save")').on('click', function (e) {
var jsonData = $('form.form-horizontal')
.find(':input:not(button)').get()
.reduce(function (acc, ele) {
acc[ele.id] = ele.value;
return acc;
}, {});
// console.log(jsonData);
alert(JSON.stringify(jsonData, null, 4));
});
$('#container').on('click', '[id^=deleteRow]', function(e) {
var jsonData = $(this).closest('.child-border, .parent-border-repeat')
.find(':input:not(button)').get()
.reduce(function (acc, ele) {
acc[ele.name || ele.id] = ele.value;
return acc;
}, {});
$(this).closest('.child-border, .parent-border-repeat').remove();
console.log(jsonData);
});

我已经解决了这个问题。
以下是回答的小提琴：AnswerFiddle
I added the Join Operator into the same "to-be-cloned" div and hid its div before cloning.
克隆后，即点击后，“+”按钮变为可见。 现在，所有前克隆和克隆后的表单字段的值都会传递给JSON。
