Upgrading JQueryPlugin to version 6.13 in an 1.1.9 installation resulted in general js failures that trace back to jquery.foswiki.js. The error given for that script is "syntaxError invalid range in character class". For some reason, this issue only shows up with minified version of the script. If the uncompressed version is used, the error disappears. This was confirmed by GeorgeClark using a fresh test installation of 1.1.9.

Googling this javascript error, I'm guessing that the issue has to do with the character lists in the definition of foswiki.RE (or else the use of that array subsequently in defining regexes). Perhaps also this issue only shows up in 1.1.9 because 2.0 installations use UTF-8 character encoding.

To complete a fine bug report it would help to know which browser you use and whether you've got an exact line/char position where that error occurs.

In the meantime I fixed a couple of jslint warnings, one of which was causing a fatal javascript error for Internet Explorers:

First, the good news: your new version of jquery.foswiki.js works fine.

Additional information on my error report: I was using using Firefox (~ver 40) on Windows 7. When using the distributed (minified) version of jquery.foswiki.js the console of course indicates the issue was on line 1. However, when I tried it in Chrome, the error still occurred but the error message specifically referred to a bad regex, so I believe it was associated with the regex defined in line 28 (of the uncompressed version) which combines the character strings defined previously.

-- LynnwoodBrown - 17 Sep 2015

It appears that the minified and compressed versions of jquery.foswiki.js and jquery.foswiki.js.gz included the JQueryPlugin download files (JQueryPlugin.tgz Version 55 and Version 63) are garbled. They both start with a string that looks like

var foswiki=foswiki||{preferences:{}};foswiki.RE={upper:"A-ZÀ-ÖØ-ÞĀĂĄĆĈĊČĎĐĒĔĖĘĚĜĞĠĢĤĦĨĪĬĮİIJĴĶĹĻĽĿŁŃŅŇŊŌŎŐŒŔŖ

The jquery.foswiki.js file in version 62 of appears to be intact and not garbled.

I see the same errors on an installation of Foswiki 1.1.9. Like Lynwood, we resolved the error by installing the files that Michael uploaded to this topic. After re-reading Lynwood's comment above about UTF-8 encoding, what I saw as "garbled" files was a difference in character encoding. For example, compare the start of the definition of upper between the files:

jquery.foswiki.uncompressed.js from JQueryPlugin 6.13:
upper : "\u0041-\u005A\u00C0-\u00D6\u00D8-\u00DE\u0100\u0102\u0104
jquery.foswiki.js from JQueryPlugin 6.13:
jquery.foswiki.uncompressed.js from this topic:
upper : "A-Z\u00C0-\u00D6\u00D8-\u00DE\u0100\u0102\u0104\u0106\u0108\u010A
jquery.foswiki.js from this topic:

Is it proper for the minified file to contain UTF-8 encoded characters or should they be escaped like in the uncompressed file and in Michael's minified file?

-- JaysonLoewen - 21 Sep 2015

Those \u escape sequences definitely need to stay intact. I don't know why they have been expanded int 6.13, but I suspect that this version of JQueryPlugin has not been build using uglify-js.

-- MichaelDaum - 21 Sep 2015

Michael, I just ran a full build of 2.0.2 using the exact same tools and procedures I did for the 2.0.1 release. Unfortunately I didn't keep the build log for 2.0 or 2.0.1. Here is what I get in a build:

Building with uglify-js 2.4.23
Building with node.js cssmin

uglifyjs /var/www/foswiki/distro/JQueryPlugin/pub/System/JQueryPlugin/plugins/foswiki/jquery.foswiki.uncompressed.js -o /var/www/foswiki/distro/JQueryPlugin/pub/System/JQueryPlugin/plugins/foswiki/jquery.foswiki.js --ascii

So I confirm that I'm using uglify.js, but the bad news is I still end up with utf-8 inside of jquery.foswiki.js. Something is going wrong here and I have no idea what. I'm reopening this because I can't release until we figure out why it's having issues on my system. Could I be using a bad version of uglify? I've added additional debug print and I'm pretty sure it's using uglify.

-- GeorgeClark - 21 Sep 2015

Updated to uglify 2.4.24, the latest. Still is generating the utf-8 version.

-- GeorgeClark - 21 Sep 2015

Updated to uglify 2.4.24, the latest. Still is generating the utf-8 version. Found the issue. uglify.js has changed their options.
