How can function be defined via "fn" member in Javascript? -

-

i found following definition

$.fn.flex = function ( options ) {    var p = this.data("flex"),            opts = options || {};    if (p) return p;    this.each(function () {       p = new flex( this, opts );       $(this).data("flex", p);    });    return opts.api ? p : this; };

which defines function flex() in original code.

unfortunately, stops defining function in environment, i.e. function call causes error flex not function.

what critical here flex being function?

update

sorry, didn't modify anything. put javascript https://github.com/jasonenglish/jquery-flex/ environment (liferay) , code run script

<script type="text/javascript">     $(function() {         $(".flex").flex();     });     </script>

caused error. replaced $ jquery everywhere did before , still not working.

update 2

hmmm. error occurs in widget.js twitter. says 

typeerror: jquery(...).flex not function

if rename flex flex1 everywhere, says "flex1" not function.

sorry, didn't modify anything. put javascript ... environment (liferay) , code run script

because that's jquery plug-in, need make sure include script after jquery on page. so

<script src="/path/to/jquery.js"></script> <script src="/path/to/the-plugin.js"></script>

if put them in other order, first script fail because try take value of jquery symbol, doesn't exist yet, throwing referenceerror (in both loose , strict mode).

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
