javascript - tablas - jQuery añadir y eliminar la fila de la tabla dinámica

tabla html añadir filas, controles y datos dinámicos con jquery, php y mysql

Question

Puedo agregar muchas filas para una tabla, pero no puedo eliminar muchas filas. Solo puedo eliminar 1 fila por complemento secuencial.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#addCF").click(function(){
$("#customFields").append(''<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" id="remCF">Remove</a></td></tr>'');
$("#remCF").on(''click'',function(){
$(this).parent().parent().remove();
});
});
});
</script>
<table class="form-table" id="customFields">
<tr valign="top">
<th scope="row"><label for="customFieldName">Custom Field</label></th>
<td>
<input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp;
<input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp;
<a href="javascript:void(0);" id="addCF">Add</a>
</td>
</tr>
</table>

Necesito ayuda.

Answer 1

Además de las otras respuestas, me gustaría mejorar la eliminación, a algo más genérico:

$(this).closest(''tr'').remove();

Esto sería mucho mejor que usar $(this).parent().parent().remove(); , porque no depende de la profundidad del elemento. Así, la estructura de la fila se vuelve mucho más flexible.

Answer 2

Cambiar ID a clase:

$("#customFields").append(''<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>'');
$(".remCF").on(''click'',function(){
$(this).parent().parent().remove();
});

Answer 3

Hay multiples problemas aqui

1. La identificación debe ser única en una página
2. Para los elementos dinámicos, debe usar la delegación de eventos usando .on()

Ex

$(document).ready(function(){
$("#addCF").click(function(){
$("#customFields").append(''<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" id="remCF">Remove</a></td></tr>'');
});
$("#customFields").on(''click'', ''#remCF'', function(){
$(this).parent().parent().remove();
});
});

Demo: Fiddle

Vea esta demostración donde se eliminan las propiedades de identificación.

$(document).ready(function(){
$("#addCF").click(function(){
$("#customFields").append(''<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>'');
});
$("#customFields").on(''click'', ''.remCF'', function(){
$(this).parent().parent().remove();
});
});

Answer 4

Por favor intente eso:

<script>
$(document).ready(function(){
var add = ''<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td>'';
add+= ''<input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" />&nbsp;&nbsp;&nbsp;'';
add+= ''<input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" />&nbsp;'';
add+= ''<a href="javascript:void(0);" class="remCF">Remove</a></td></tr>'';
$(".addCF").click(function(){ $("#customFields").append(add); });
$("#customFields").on(''click'',''.remCF'',function(){
var inx = $(''.remCF'').index(this);
$(''tr'').eq(inx+1).remove();
});
});
</script>

Answer 5

Puede agregar y eliminar dinámicamente filas de tablas como esta en la imagen usando jQuery.

Aquí está la parte html ...

<form id=''students'' method=''post'' name=''students'' action=''index.php''>
<table border="1" cellspacing="0">
<tr>
<th><input class=''check_all'' type=''checkbox'' onclick="select_all()"/></th>
<th>S. No</th>
<th>First Name</th>
<th>Last Name</th>
<th>Tamil</th>
<th>English</th>
<th>Computer</th>
<th>Total</th>
</tr>
<tr>
<td><input type=''checkbox'' class=''case''/></td>
<td>1.</td>
<td><input type=''text'' id=''first_name'' name=''first_name[]''/></td>
<td><input type=''text'' id=''last_name'' name=''last_name[]''/></td>
<td><input type=''text'' id=''tamil'' name=''tamil[]''/></td>
<td><input type=''text'' id=''english'' name=''english[]''/> </td>
<td><input type=''text'' id=''computer'' name=''computer[]''/></td>
<td><input type=''text'' id=''total'' name=''total[]''/> </td>
</tr>
</table>
<button type="button" class=''delete''>- Delete</button>
<button type="button" class=''addmore''>+ Add More</button>
<p>
<input type=''submit'' name=''submit'' value=''submit'' class=''but''/></p>
</form>

Siguiente necesidad de incluir jquery ...

<script src=''jquery-1.9.1.min.js''></script>

Finalmente el script que agrega las filas de la tabla ...

<script>
var i=2;
$(".addmore").on(''click'',function(){
var data="<tr><td><input type=''checkbox'' class=''case''/></td><td>"+i+".</td>";
data +="<td><input type=''text'' id=''first_name"+i+"'' name=''first_name[]''/></td> <td><input type=''text'' id=''last_name"+i+"'' name=''last_name[]''/></td><td><input type=''text'' id=''tamil"+i+"'' name=''tamil[]''/></td><td><input type=''text'' id=''english"+i+"'' name=''english[]''/></td><td><input type=''text'' id=''computer"+i+"'' name=''computer[]''/></td><td><input type=''text'' id=''total"+i+"'' name=''total[]''/></td></tr>";
$(''table'').append(data);
i++;
});
</script>

Answer 6

Solo puedes tener una ID única por página. Cambie esos ID a clases y cambie los selectores jQuery también.

Además, mueva el .on () fuera de la función .click (), ya que solo necesita configurarlo una vez.

http://jsfiddle.net/samliew/3AJcj/2/

$(document).ready(function(){
$(".addCF").click(function(){
$("#customFields").append(''<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>'');
});
$("#customFields").on(''click'',''.remCF'',function(){
$(this).parent().parent().remove();
});
});

varíe la forma sencilla en que puede resolverlo ... eche un vistazo a mi nuevo código recopilado.

 $(document).ready(function(){
$(".add-row").click(function(){
var name = $("#name").val();
var email = $("#email").val();
var markup = "<tr><td><input type=''checkbox'' name=''record''></td><td>" + name + "</td><td>" + email + "</td></tr>";
$("table tbody").append(markup);
});
// Find and remove selected table rows
$(".delete-row").click(function(){
$("table tbody").find(''input[name="record"]'').each(function(){
if($(this).is(":checked")){
$(this).parents("tr").remove();
}
});
