Does binding events to elements in jQuery multiple times have a knock on effect?

Question

If I have the below code, textboxes of class serial will be bound to the events more than once if the new serial button is pressed multiple times.

Will this hinder

Answer 1

Well i think this causes a lot of overhead and some problems because the events are binded more than once. Look at this simple fiddle: http://jsfiddle.net/nicolapeluchetti/syvDu/

Button
Serial
Serial
Serial

MonitorSerialTextBoxes();

$('#newSerial').click(function() {
    MonitorSerialTextBoxes();

});

function MonitorSerialTextBoxes() {
    $('.serial').each(function() {


        // Look for changes in the value
        $(this).bind("click", function(event) {
            alert("hi");
        });
    });
}

When you load the page a single alòert is displayed when you click on a div, but each time you press the button one more alert is displayed because a new event is attached
