jQuery 1.7.2 Beta 1 Released

Posted on by

Hey there Internets, it’s the jQuery Core team! We haven’t talked in a while, but over the holidays we were busy fixing the bugs you reported. The result of that hard work is jQuery 1.7.2 Beta 1. We decided to get a beta out by Groundhog Day so you wouldn’t be in the shadow of six more weeks of unfixed bugs.

You can get the code from the jQuery CDN:

Oh, we know what you’re thinking: “Cool, a new version of jQuery; I’ll wait until the final release has been out a few weeks and then I’ll give it a try.” Right, and then you’ll find some bug that keeps you from upgrading. Nothing makes us sadder than finishing up a release and only then seeing a report of a serious bug that could have been fixed earlier.

So please, come out of your burrow and try this beta with your code. Did we miss an old bug? Did we create a new bug that makes you feel like Bill Murray waking up to “I Got You Babe?” We want to know. You can use the bug tracker to report bugs; be sure to create a test case on jsFiddle so we can figure it out easily. If you’re not sure it’s a bug, ask on our forum or on StackOverflow.

    D, it’s easy. All you have to do is switch out th e version n that you are using for this one. Run through your code and see if anything breaks. If it does you then check if it’s a plugin that is broken. If it’s a plugin, report the issues to the plugin author. r. If not, then consult the api see if your code is using unexpected behaviour. If that’s not the case, you might have a bug in jQuery. From there, try and see if you can replicate it simply, without your business logic. Use something like jsfiddle. Once you’ve done that, see if your bug has been reported. If not then go ahead and report it.

    I hope this helps.

  2. Love jquery. It would be nice if someone can show me how to use ajax call and showing a progress bar indicator. What I’m trying to do is to use ajax to upload the photos to the server but unable to use the onprogress event.

  3. You guys know your Trac system is down, right? At least trying to view the bugs from this blog post gives an error. Has for a few days for me.

  4. Hey there.

    This is a bug in Opera 12.00 (not in earlier versions, but has been there forever in v12), and not in jQuery, but it can be fixed in jQuery. I reported the bug to Opera a few months ago, but they never did anything about it. If you run Opera 12 on any website, Inspect Element, go to the Properties tab on the right pane, then unfold ‘style’, you’ll see that ‘zoom’ is in the list, with an empty value.

    Because jQuery tests for style.zoom to match IE, it will run the IE code path and set style.zoom to 1, which generates a CSS error in Opera.

    As I said — it’s no biggie, but it would still be nice of you if you could do something about it, or even better, complain in an official manner at Opera so that they fix it before their final 12.00 release. You probably have more weight and voice than a single developer. I always have the console opened and it’s an error I’m seeing every time. Thanks :)

  5. Drag and drop partially broke when I upgraded from 1.6 -> 1.7.2 beta. Basically, it became hard to find the ‘sweet spot’ for dropping an image within the drop target rectangle. I don’t know why this is.

    Thankfully, the issue with the jQuery UI blog being marked as malicious seems to be resolved now.

  7. What is the correct operation for the “.on” click event handlers? Because ctrl+click won’t open a new tab, but middle click will (so it is not catched).

  8. i have issues with jquery.ui-selectmenu and Firefox 13 (nightly).
    a new “select” appears evertime i call .selectmenu().
    maybe it’s a selectmenu-issue or a jquery&ff13 issue ?!

    Windows 8 Consumer Preview was also recently released together with IE10 Preview 5, so make sure all tests in v1.7.2 runs OK in this browser.
