Below is a prototype.js 1.7.1 version

  getElements: function(form) {
var is_chrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1;
var elements = $(form).getElementsByTagName('*'); 
if(is_chrome){
    var elements = $(form).select('*');     //still problem in chrome
    console.log(elements.length);
}
var element, results = [], serializers = Form.Element.Serializers;
for (var i = 0; element = elements[i]; i++) {
  if (serializers[element.tagName.toLowerCase()])
    results.push(Element.extend(element));
}
return results;
