Low Pro for Prototype and Firefox 3.5

02 JUL

Just a quick note for those googling for a solution to this. Older versions of Low Pro for Protoype will be experiencing problems with behaviors in Firefox 3.5. This issue has been fixed so pick up the latest version from GitHub

An interesting upshot of this is that I found out something pretty nice which is kind of obvious but had never occurred to me before. If you create a function in a closure then that function can refer to itself because it has access to that closure’s variables. I normally use arguments.callee to get a reference to a function from within its body but there’s never really any need to do that:

(function() {
  var aFunction = function() {
    aFunction.thing = 47;
  };

  aFunction();

  alert(aFunction.thing); //=> 47;
})();

You can use the “named function expression” form (I just made that term up) to do what you want I think:


var foo = function bar() {
  // do stuff here.
  bar(); // recurse...
}

foo(); // will recurse.

Thanks for warning. I was googling about this problem, and your post just came in front of my browser.

Now my problem with low pro is fixed.

Thanks

I noticed that adding dynamic content, like for example a link with class “remote” doesn’t work anymore. When I click on the link, it doesn’t act as a remote link, instead it acts as a regular html link and doesn’t execute ajax.

Any idea why that is?

It used to work fine before this update.

Hey, thanks for the tip, that did the trick!

Might I suggest adding a minor-revision number for this bugfix? When I first found this post, I compared the “LowPro.Version = ‘0.5’;” in the GitHub version against my “LowPro.Version = ‘0.5’;” in my production version and assumed we were already up to date. :)

Thank you for this post! This is going to save me some hassle!

You should add a new version number (like 0.5.1) to the code so that it tells those who only check version numbers that something has changed!

Keep up the great work!
