in thread On Line Book - Exploring Programming Language Architecture in Perl - Updated

With or without JS enabled, when I click the link bottom-left of the title page, it takes me to http://billhails.net/Book/front.html which comes up entirely blank using my preferred browser (Opera). I viewed the source and saw the reference to book.js and attributed the problem to that.

I just sparked up an (relatively ancient) version of Firefox and the page loads fine there. Looking at the JS, I suspect DOM differences for Opera vs. FireFox.

    Hmm, OK, thanks for that. If this breaks Opera, I'd better fix it!

    Odd, I just downloaded Opera (for Mac) and browsed to the book. It works fine for me. I'll try with a FreeBSD Opera when I get to work tomorrow morning.

      Maybe it's a problem limited to the version of Opera I use, v8.51, though I get the same effects with v6.06 which I keep around for historical reasons. I tried v9 but didn't like it so I reverted.

      If I save the source to a local file and comment out the script tag, it loads and displays. If I copy the contents of book.js and embed them within the local html file, it loads and displays. But if I copy the js to a local file and reference from the local html, I get the blank screen again.

      It's probably a browser/version specific bug, and so not worth your while persuing.

        The link works for me in Firefox 2.0.0 but not in IE 7.0.5

        UPDATE

        Now working in IE7 too.
