You could use the function that changes the text of span1 to change the text of the others.

As a work around, if you really want it to have a change event, then don't asign text to span 1. Instead asign an input variable in jQuery, write a change event to it, and whever ur changing the text of span1 .. instead change the value of your input variable, thus firing change event, like so:

var spanChange = $(<input />);

function someFuncToCalculateAndSetTextForSpan1() {

    //  do work

    spanChange.val($newText).change();

};



$(function() {

    spanChange.change(function(e) {

        var $val = $(this).val(),

            $newVal = some*calc-$val;

        $(#span1).text($val);

        $(#spanWhatever).text($newVal);

    });

});

Though I really feel this work-around, while useful in some aspects of creating a simple change event, is very overextended, and you'd best be making the changes to other spans at the same time you change span1.
