Hrefs vs JavaScript onclick (regarding unobtrusive JavaScript)

What is the best practice of using links / <a> tags with explicit hrefs to other pages on your site (i.e. href = "/ blah / blah / blah.html) against having hrefs / divs / etc. that don’t have explicit href, and their onclick set in the finished document handler with JavaScript in the main.js.

I'm not an expert when it comes to web development, but I like to learn jQuery and the like, and I approach the concept of unobtrusive JavaScript. Although both options above do not break the “do not have JavaScript in HTML” part of this mentality, I believe that I hung up on “Separation of structure and presentation from behavior”. Although, admittedly, it was more natural for me to put a <a> tag and explicitly set href, I believe that this is really a behavior and should therefore be set in JS.

Is it really far, or am I just not used to it? The other side of me sees the advantage of putting it in JS, b / c, now I have the ability to completely control the behavior of this link without changing anything in the HTML. You'll probably say that I'm on the notorious fence. Please help me. =)

(One note: the site makes heavy use of JavaScript, so the concept of providing JS functions is disabled, it is not really a concern, since most of the site will not work without it.)

This is really too far for many reasons.

  • This is complex code that should be avoided.
  • This does not provide tangible benefits for your site.
  • It does not have an eloquent reserve for no-js.
  • This has a negative impact on SEO. In particular, bots will not run your script and therefore will not see links and, ultimately, will not index your site correctly.

The jquery history plugin is pretty nice, it allows you to set href = '# / url' so that you can have real urls, real buttons back, but your hand tools just listen for events related to history.url.

Unused tags can probably also have some usability problems for visually impaired users using on-screen programs.
