Javascript goodies

Today, I spend quite some time refactoring messy Javascript code:

1.) I needed to extract a number appended to the end of the string - use the power of regular expressions to make this one clean and sleek.

var RowIdNumber = rowId.match(/\d+$/)[0];

2.) To obtain a 'anchor' element inside of a table row and invoke it's click (href) -

rows[i].getElementsByTagName("a")[0].click();

Enjoy :)
