Oh wow ... no offense but I haven't seen such code in a while :) .. I
see the code but it's difficult to understand the problem that you are
trying to solve ... looks like you are building a clock. For building
reasonable small JavaScript I'd recommend using Lif't's JavaScript
abstraction (JsExp/JsCmd etc). For bigger JS code I'd recommend
writing the JavaScript code in the JS file and define your own
JavaScript objects.
So what I'd do:
1. Define the JavaScript function in a separate .js file (the function
may be part of a JS JSON object )
2. The function would take a JSON structure as argument
3. From the Lift's snippet generate the JSON structure that needs to
be passed to you function using JsObj and generate the <script> tag
(using xml literals or even use the JsCmds.Script object). Potentially
use JqOnLoad so that
your function to be called after the DOM tree is loaded
