  • Semantics when using Javascript

    Just a quick question,

    I have images that can be clicked on to pop up a larger image in a new window.

    I am using <a> anchors to achieve this, but since everything is done in Javascript, I leave the href as "#something"... but it occurs to me that this might not be the most semantic way of doing this...

    What's the most "official" way to handle href semantics when using Javascript?

    Alternatively, I could put an "onclick" function on the IMG tag directly and change the cursor for the IMG through CSS... this seems preferable to me, but what do other people think?

    I would personally do something like:

    <a href="linktolargerimage.html"><img blabla/></a>

    Then set the onclick handlers dynamically through Javascript to open the image in a new window. Thus, when JS is disabled, the link is still useful.

      Using return false is the best method; if the user does not have Javascript they are taken to the link, if they do then the function is run.

      <a href="largerimage.jpg" onclick="functiontoshowlargerimage(); return false;"><img src="smallerimage.jpg" /></a>

        Hi... thanks for the reply.

        The only problem with either of these methods is that if Javascript IS enabled, the picture is popped up in a new window AND the link takes takes the user to the new page/pic...I can't figure out how to make the browser ignore the HREF if Javascript works...

          That's what the "return false" takes care of… if the javascript is executed, then the normal action of the link isn't.
