It appears that this method of relocation is discouraged by w3c mainly because it excludes users without javascript. There are other disadvantages to this method, namely that these links (sometimes referred to as pseudo-links) don't offer the functionality that regularly-formed links do. You cannot preview the URL of the page the link will lead to, open the URL in a new window or a new tab, for example. There is also the structural argument against this form of linking that a site's navigation should be inextricably tied to its structure and content. This is a widely held view amongst the very best in this field. (See Web Site Usability by Jared M. Spool et al., 1999.)However, in practice if you do wish to use it, it can be relied upon to function correctly in all enabled browsers
