Convert standalone Javascript to widget -

we have 8,300-line javascript application, implements interactive diagram hand of bridge. it's written 250 top-level variables, 250 functions, 130 lines of driver code outside of functions, , 30 hard-coded element ids referenced in various places; it's entirely self-contained, no libraries used. gets parameters url query string. way use on web pages load in iframe.

this implemented 3 files:

• handviewer.html - page point in iframes. contains 70 lines of html required divs, , loads css , js (called handviewer-old.html in test below)
• hvstyles.css - css page
• handviewer.js - javascript code described above

in handviewer.html, active elements have inline onclick attributes call functions in handviewer.js.

the problem when embed lots of these on page, performance suffers. iframes pain begin with, , lots of them pointing same server run connection limits. , though they're pointing @ same script, parameters in query string act cache-buster. loading page 12 of these diagrams takes 3-5 seconds reasonably fast browsers. looking @ timeline, can see loads staggered. i'd convert widget can applied div, parameters inline arguments.

a test page these 12 iframes at:

http://dev.bridgebase.com/barmar_test/many-hv-old.html

i'm preparing hand -- i'll wrap function around whole thing, replace ids classes, document.getelementbyid(x) becomes thediv.getelementsbyclass(x)[0], , rewrite function extracts query string parameters them options argument. wonder if there tools around can assist in process. if has done conversion this, have techniques help?

i took @ code ...

if(carddivs[seat][suit][i].innerhtml=="") ...

don't that. make classic js array of booleans mark "empty items".

and generally, don't access dom much. seems, whole "model" (from mvc terminology) , application state stored in dom.
