You should always iterate Array objects using numeric iteration or
Array.prototype iteration. What you're doing is object property
iteration. Array has properties in addition to its members.
// traditional iteration
for (i = 0; i < elements.length; i++) {
alert(
'the id key is ' + parseFloat(elements[i].substring(4)) +
' and the value is " + elements[i].innerHTML
);
}
// Array.prototype iteration (Prototype Enumerable#each)
elements.each(function(element) {
alert(
'the id key is ' + parseFloat(element.substring(4)) +
' and the value is " + element.innerHTML
);
});
