You can use .on() to bind a function to multiple events:

$('#element').on('keyup keypress blur change', function(e) {
    // e.type is the type of event fired
});

Or just pass the function as the parameter to normal event functions:

var myFunction = function() {
   ...
}

$('#element')
    .keyup(myFunction)
    .keypress(myFunction)
    .blur(myFunction)
    .change(myFunction)
