The change event occurs when the value of an element has been changed (only works on <input>, <textarea> and <select> elements). The change() method triggers the change event, or attaches a function to run when a change event occurs. Note: For select menus, the change event occurs when an option is selected. For text fields or text areas, the change event occurs when the field loses focus, after the content has been changed When you create an <input> tag in HTML, you can optionally set the default value (which the user can then change) by using the value= attribute. The val() method, however, does something a little bit different — it sets the value after the input is created, and very possibly after the user has already entered a value. That's probably not something that you would want to do with most inputs, but there are times when you may want to do it — in response, for example, to a user.
