   </body>
</html>

index.js

$(document).ready(function(){
    //group add limit
    var maxGroup = 15;
    
    //add more fields group
    $(".addMore").click(function(){
        if($('body').find('.fieldGroup').length < maxGroup){
            var fieldHTML = '<div class="form-group fieldGroup">'+$(".fieldGroupCopy").html()+'</div>';
            $('body').find('.fieldGroup:last').after(fieldHTML);
        }else{
            alert('Maximum '+maxGroup+' groups are allowed.');
        }
    });
    
    //remove fields group
    $("body").on("click",".remove",function(){ 
        $(this).parents(".fieldGroup").remove();
    });
});

现在我想要做的是在数组中获取表单的值

[{'name': 'inputname', 'email': 'inputEmail'}, {'name': 'inputname', 'email': 'inputEmail'},]

如您所见，我在 JSON 中有 2 个数组，我想要我的数据，因此添加多少表单会增加数据。

解决方案

https://api.jquery.com/serialize/

尝试序列化，方法遍历指定字段并收集数据
