jQuery action whenever any select is changed

开发者_JS百科Using jQuery, how can I make it so that a function is called whenever any select object on the page is changed?

You can bind the change event to all the select elements on the DOM:

$('select').change(function () {
  // do something
});

Inside the event handler, the this keyword refers to the select element triggered the event, and you can get it's attributes, eg. var selectId = this.id;
