Using jQuery you can use the attr starts with selector:

var dates = $('[id^="createdOnid"]');

Using modern browsers, you can use the CSS3 attribute value begins with selector along with querySelectorAll:

var dates = document.querySelectorAll('*[id^="createdOnID"]');

But for a fallback for old browsers (and without jQuery) you'll need:

var dateRE = /^createdOnid/;
var dates=[],els=document.getElementsByTagName('*');
for (var i=els.length;i--;) if (dateRE.test(els[i].id]) dates.push(els[i]);
