Using OO Javascript to create DOM elements and CSS Style

A lot of javascript tricks use CSS classes to toggle graphic properties, such as .mygoldbackground { ... } .mygreenbackground {...} and the js resets the classname of the HTML element. This is fine for most scenarios.

I am writing games where the CSS is much more dynamic, and I was constantly having to edit the CSS to match up with the game board layout ( for early prototype example of my players and game boards, see: http://my-toolbox.appspot.com/javascript.js?queryvalue=critters%201.2&dbtab=show )

So I am going to 1) create all game DOM elements with js 2) set all game DOM CSS with js.

Here is the core toolset of code for doing that:

• http://my-toolbox.appspot.com/javascript.js?queryvalue=javascript%20object%20oriented%20createElement%20cssText%20&dbtab=show
• http://my-toolbox.appspot.com/javascript.js?queryvalue=javascript%20object%20oriented%20DOM%20makebox&dbtab=show

Documenting behavior of the Google Cloud

This is a non-dynamic webpage documenting the database object insert timing for the Google Gdata object. I thought the randomness of insert completion of each node to be interesting and shows the "cloud" in action. Note the python code at the bottom of this page (here). The "nodes" were executed 1...64 in the python script, so it is easy to see where the cloud disengages from that linearity.
