Can jQuery check whether input content has changed?

Question

Is it possible to bind javascript (jQuery is best) event to \"change\" form input value somehow?

I know about .change() method, but it does not trigger

Answer 1

You can also store the initial value in a data attribute and test it with the current value.

 

$("#id_someid").keyup(function() {
    return $(this).val() == $(this).data().initial;
});

Would return true if the initial value has not changed.
