Cómo volver a cargar el objeto jquery dropkick

Question

Im usando una lista de selección simple y la biblioteca jquery.dropkick para que sea hermosa. Ahora quiero cambiar ese contenido dropkick después de que se haya cambiado el elemento de selección correspondiente (una nueva opción entró). Pero simplemente llamando a $ ('# select'). Dropkick(); no funciona

Y parece que no es compatible. Sería suficiente reconstruir ese dropkick desde cero. ¿Hay alguna posibilidad de "destruir" ese objeto dropkick y luego reconstruirlo llamando al método .dropkick()?

Answer 1

Me he enfrentado al mismo problema y no he podido encontrar una solución, pero finalmente logré que este truco funcione.

$select = $("#select1"); 
$select.removeData("dropkick"); 
$("#dk_container_select1").remove(); 

$select.append("<option>opt4</option>"); 
$select.append("<option>opt5</option>"); 

$select.dropkick(); 

Answer 2

Para visitantes nuevos. Dropkick added redraw method.

$("select").dropkick('redraw'); 

Answer 3

Para aún más visitantes. Dropkick usa el método de reinicio ... no vuelve a dibujar.

$("select").dropkick('reset'); 

Answer 4

me encontré con el mismo problema, he hecho algunos parches al script jQuery-patada-1.0.0 para resolver este problema. Agregué un método forceSyncWithSelect al objeto dropkick.

He aquí una lista de los cambios que hice:

• añadir soporte para la etiqueta
• agregar configuraciones ANCHO AUTO dejar el ancho de css
• método add para abrir, cerrar, forceSyncWithSelect y isDropkicked
• torreón tabindex predeterminado 0
• agregue la opción optgroup class con el atributo data-dkgroupclass en el elemento op
• f Método ix forceSyncWithSelect si el valor de aparecer varias de tiempo, tomar la primera ocurrencia única
• de palanca al hacer clic en el menú de selección
• prevenir la EI se cierre el menú en la interacción barra de desplazamiento (un evento de desenfoque se puso en marcha en la interacción barra de desplazamiento, este comportamiento es tan malo)

puede que no quiera a todos los cambios, pero se puede hacer un parche de diferencias y de tomar lo que necesita (que sería feliz si deja que el registro de cambios o agregar la fuente de la misma en la cabecera, Quiero proponer esos cambios a Jamie Lottering, pero necesito hacer una cuenta de git hub para hacerlo.

Answer 5

I apalancado respuesta de diodo para modificar el código de Dropkick para hacer esto un poco más limpio:

// Reload the dropkick select widget after options have changed 
// usage: $("...").dropkick('reload'); 
methods.reload = function() { 
    var $select = $(this); 
    var data = $select.data('dropkick'); 
    $select.removeData("dropkick"); 
    $("#dk_container_"+ data.id).remove(); 
    $select.dropkick(data.settings); 
}; 

Añadir el código de arriba a la derecha después de que el siguiente fragmento de patada.JS:

methods.reset = function() { 
    ... 
}; 

continuación, puede utilizar mediante programación:

$('#my-select').html("<option>new options</option>"); 
    $('#my-select').dropkick('reload'); 

Answer 6

$('#select').html('<option>a</option>').dropkick('refresh');
