Reset fields to default values using jQuery
Have you ever wanted to reset only fields in a particular section of the form without resetting all of the fields?
Here is how you can achieve this with jQuery 
$('#reset_address').click(function (event) {
event.preventDefault();
$('#address_details :input').each(function() {
if ($(this).is('select')) {
$(this).val($(this).find('option[selected]').val());
} else {
$(this).val(this.defaultValue);
}
});
});
#address_details represents a <fieldset> within my <form>. When the user clicks the #reset_address link I revert the fields within the <fieldset> (not the entire form) back to their original values.
Note: defaultValue is a core JavaScript property. A conditional check for <select> was necessary since defaultValue only applies to <input> and <textarea> fields.
