En este post veremos algunar formas para manipular un  “select”  mediante jQuery.

Agregando mediante html.

Una  de las formas mas sencillas es agregar la opción mediante codigo HTML como tal, y agregarselo a select mediante append.

$('#example').append('<option value="foo" selected="selected">Foo</option>');


Mediante la forma “new option”

Una forma un poco más  adecuada es usando la el metodo new option(). a un que esta forma podria no funcionar muy bien en internet explorer ¬¬.

$('#example').append(new Option('Foo', 'foo', true, true));


Agregando multiples options.

En el siguiente codigo estaremos agregando 4 optiones al select con id = #example.

var newOptions = {
    'red' : 'Red',
    'blue' : 'Blue',
    'green' : 'Green',
    'yellow' : 'Yellow'
var selectedOption = 'green';

var select = $('#example');
if(select.prop) {
  var options = select.prop('options');
else {
  var options = select.attr('options');
$('option', select).remove();

$.each(newOptions, function(val, text) {
    options[options.length] = new Option(text, val);


Limpiar nuestro select



Seleccionando una opción median Js

Con esta funcion vamos  a setear el valor que queremos se seleccione en un determinado select.

bastara con enviar como parametros el nombre del Id, y el value que queremos seleccionar.

    function setValueSelect(SelectId, Value) {
        SelectObject = document.getElementById(SelectId);
        for(index = 0;  index < SelectObject.length;  index++) {
            if(SelectObject[index].value == Value) SelectObject.selectedIndex = index;


Código del formulario

  1. Ok funciona pero con valor pre-determinado, y si lo que deseo es tomar los datos de una base de datos, mostrarlos en el Select, y cuando doy click al boton agregar, me deje escribir la opcion y la muestre en el select (Sin borrar la info anterior)

    1. Bueno en este caso necesitaras un poco mas de código JS para mandar un promp o la ventana de dialogo, y después usar la linea $(‘#example’).append(‘Foo’);

      Con esto se agregara pero no se eliminan las anteriores.

  2. ¿Y para poner yo desde el formulario el valor que quiero?

    Even though I jokingly credit my aunt for my writing talent, I know that it is a talent I have fostered from childhood. Though my aunt is a writer, I also started out young.
    I’ve always had a way with words, according to my favorite professor . I was always so excited in English when we had to do a research paper .
    Now, I help current pupils achieve the grades that have always come easily to me. It is my way of giving back to students because I understand the obstacles they must overcome to graduate.
