</div>

當用戶按下「添加」就必須添加一個新行中輸入相同的日期，但添加到每一行的按鈕，編輯當前行並將其刪除。，所以你可以添加N元素並刪除逐行（或逐個編輯）。

    <body> 
    <div class="container"> 
    <div class="row main" id="main"> 

     <div class="col-xs-12 col-md-3 "> 
       <input type="text" id="txtNombre" placeholder="Usuario" required="" autofocus="" class="form-control" > 
     </div> 
     <div class="col-xs-12 col-md-3 "> 
       <input type="text" id="txtTelefono" placeholder="Telefono" required="" autofocus="" class="form-control" > 
     </div> 
     <div class="col-xs-12 col-md-3 "> 
       <input type="text" id="txtDireccion" placeholder="Direccion" required="" autofocus="" class="form-control" > 
     </div> 
     <div class="col-xs-12 col-md-3 "> 
       <input type="text" id="txtEmail" placeholder="Correo" required="" autofocus="" class="form-control" > 
     </div> 
    </div> 
    <div class="row buttonbox"> 
     <div class="col-xs-12 col-md-3 col-md-offset-9 "> 
      <button type="button" class="btn btn-success add" >ADD +</button> 
       <button type="button" class="btn btn-danger remove" >DEL -</button> 
     </div> 
    </div> 

</div> 
    </body> 

</html>

和JS

// Add your javascript here 
$(function(){ 
    var i = 0; 
    var last12 = $('.buttonbox').last(); 
    $(document).on('click', '.add', function() { 

    var clone = $('#main').clone(); 
clone.find("input").val(""); 
clone.attr("id", "main" + i++).insertBefore(last12); 



     //clone.id = "main" + i; 

    }); 

    $(".remove").click(function(){ 

    $('.main:last').remove(); 
    }); 
});

可以克隆上述股利和添加再次

更新您的HTML中加入2按鈕添加和排減，

HTML

<div class="row"> 
<!--For adding row--> 
<div class="col-xs-12 col-md-3 col-md-offset-9 "> 
    <img src="#" class="agregar" id="btnadd" autofocus="" > 
</div> 
<!-- for removing rows-->  
    <div class="col-xs-12 col-md-3 col-md-offset-9 "> 
     <img src="#" class="agregar" id="btnrmv" autofocus="" > 
    </div>

更新JS，

$(document).ready(function(){ 
$("#btnadd").click(function(){ 
$(".container > .row:first").clone().insertBefore('.row:last'); 
}); 
$("#btnrmv").click(function(){ 
$(".row:first").remove(); 
}); 
});

因此，每一次，當用戶點擊#btnadd它添加一個和onclick #btnrmv它刪除一個。
