The online documentation for the progressbar plugin for jQuery.UI says to use “progress” as the keyword when setting the value of your progress bar, something like this:

var percent = Math.floor(data.received / data.size * 100);
$(“#upload-progress”).progressbar(‘progress’, percent);

It doesn’t work. At least, it doesn’t work with the 1.6rc5 release. The correct keyword for setting the value is “value”:

var percent = Math.floor(data.received / data.size * 100);
$(“#upload-progress”).progressbar(‘value’, percent);

The documentation doesn’t mention the default range of values for progressbar, but it is from 0 to 100. Actually the docs have all this stuff about showing custom text and the numeric value in the bar and that doesn’t seem to work neither.

In a way this small imperfection makes me admire jQuery even more. And this post is a kiss on her cheek.

I’ve filed a bug! [#3871 on jQuery.UI’s Trac](http://ui.jquery.com/bugs/ticket/3871).
