Leave the markup as-is and replace the Prototype script with this
jQuery. I tried to make the selectors do most of the work, but it
still has the downsides of the original code such as not validating
price inputs.
$(function(){
var calculate = function() {
var total = 0;
$("tr.fieldpair:has(:checked) :text").each(function(){
total += +this.value;
});
$("#total_amount").text(total);
};
calculate();
$("tr.fieldpair :checkbox").click(calculate);
$("tr.fieldpair :text").keyup(calculate);
});
