ADC Rates Web Browsers For Javascript Compatibility

      If you consider that the web is used for a lot more than academic papers in the year 2003, you'll be quite suprised to find that JavaScript w/ DOM bindings can be quite useful in helping to make web _application_ interfaces suck less. HTML makes an....um...interesting presentation layer for lots of stuff, application data included, but when you want to do something with that data, HTML's cracks start to show.

      Excluding [XML test] Safari was the only browser that was perfect on all tests.

      I don't have a Mac to test on but at least my old Nightly Build of Mozilla 1.3b (ID:2003021806) does render also the DHTML test perfectly[1]. You're right that the XML test is broken (the server is misconfigured).

      [1] Or... it does display and remove the scrollbar as expected when the div goes over (under?) the right edge of viewport. However, it doesn't display the scrollbar when the div goes over the left border of the viewport, which I consider as a bug also. It's the bug ID:6976 in case you want to vote it. Don't post extra comments to that bug unless you have a fix.

      What would you rather Steve said? "Safari is insanlely great!"? Apple posted a reproducable test suite that outlined some of Safari's positives and negatives. As for Apple saying "We're Great", the conclusion reads "The new Safari 1.0 beta is a strong contender." Safari went toe-to-toe with Mozilla and came out alive. That is quite an accomplishment and Apple should be commended for it.

      ... There's no telling how many tests where done, but whose results we won't get to see until they have fixed the bugs. Let's see some tests from an independant third party. I bet Safari won't get "Perfect except for that W3C draft thing which no browser except Mozilla support, test that seems like it was put in there just so Safari would fail it, and the test will look more neutral".

    I'll bet the reason Safari couldn't handle that XML -- which Mozilla 1.3b didn't run on my debian system until I copied it locally and fixed the XML problems -- was that it wasn't really XML. The MIME type is "text/plain" and it didn't have a proper XML declaration.

      Running IE6 on w2k, it fares quite well.

      The only test it seems to have some issue with is the W3CDOM test where it creates form fields on the fly.

      It creates the fields, but the radio buttons don't seem to accept a click. This may have to do with the fact that the radio buttons don't have a name attribute. I've noticed before that IE (at least mine) doesn't like unnamed radio buttons (as that's how it knows how to group them).

      Otherwise, the other tests worked quite well.

  8. The XML test... by Anonymous Coward · · Score: 2, Insightful

    I thought the whole point of these tests was to measure the brwoser's standards compliance. Then they go and code their javaScript (for the XML test, at least) such that there is a specific implementation so that IE will work since IE doesn't support the method called for by the standard.

    What's the point of testing browser compliance if you're going to execute separate code for specific browsers? Why not just check the navigator.appName and then write browser specific javaScript code like we've had to do ever since IE entered the browser war?

    1. Re:The XML test... by russcoon · · Score: 3, Interesting

      navigator.appName checking isn't portable, and it can be quite verbose (requires a check per browser per feature), whereas object detection (which is what they're doing here) allows you to detect whether or not a specific feature is supported without knowing what browsers support it.

      Browser specific hacks are what got us into the document.all vs. document.layers mess in the 4.0 days anyway.

      As for browser-specific-code WRT to the XML loading thing, there's little (if any) support for DOM 3 Load And Save (as there's no public spec yet), so executing conditional, browser specific code to get this functionality is necessaray. Mozilla has implemented the XMLHTTP object that first appeared in IE, and so it's kind of the defacto standard (similar to innerHTML, which would also go away with DOM 3 Load And Save), however creating these objects is different on the various platforms, and is again not standard.

  10. not a total waste of time... by russcoon · · Score: 5, Informative

    This article isn't bad, but it only scratches the surface of a lot of more insidious problems with all the browsers "tested".

    For instance, no real differentiation is made between DOM 0, DOM 1, and DOM 2 style events and their setters. There's not even a whisper about mutation events. The section on "display" properties totally misses the related (and more useful) problems of using attribute getters and setters in the various browsers. Ever tried setting a div to have overflow="scroll" on Safari?

  12. They did not test JavaScript by DeadSea · · Score: 3, Interesting
    I would be very interested to see how regular expressions (a core part of the JavaScript language) stack up in various browsers. Netscape has had good support for regexps since 4.0, IE since 5.0. Opera still seems to be lacking in these regards.

    I'm basing this on my experience writing a contact form that thwarts spam. It has (optional) client side verification of the fields based on regular expressions. (The same regular expressions are then used again on the server, the client side stuff just makes it fail fast.) When a web browser thinks it supports JavaScript, but doesn't do it well enough this runs into problems. I keep finding browsers that like the regular expressions I use.

    If you are using an uncommon browser, I would appretiate the testing. Please go to my contact page and fill out a valid email address but no subject or message. If your browser works correctly, you should not get an error about the email address. Then send me the results. (If you do have problems, disable JavaScript first.)

    Opera and Mozilla both handled everything flawlessly except for the XML. Neither seemed too happy with the imported XML text, instead remaining blank. On the other hand, I.E. rendered all of the above with no problems.

    In any case, you shouldn't be importing your site's content as XML anyway, as another poster pointed out. If you have to, your site will be I.E. only for now. Unless they have a Mac.
