I have a XSL that created multiple elements with the id of createdOn plus a $unique-id

Example : createdOnid0xfff5db30

I want to find and store these in a variable using JavaScript. I've tried

var dates = document.getElementsById(/createdOn/);

but that doesn't appear to work.

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]);
