JavaScript for the BlackBerry browser

[LFI]

Hey, all! I'm currently writing BlackBerry counterparts to a few of my company's important desktop applications (specifically our timesheet program, but also some others). The differences between programming for a monitor-sized screen and IE6 Browser with a "standard" keyboard at your disposal and programming for the thumb-typist on a little screen with the limited HTML and JavaScript (and CSS for that matter) that the BlackBerry can handle has required strategizing to the extent that I am using it as a topic for my Master's Project (lower expectations than a full-blown thesis).

I was wondering if anyone had any experience with the BlackBerry browser and what you have discovered regarding it and the use of JavaScript. I can use all the fodder I can get. I just uncovered a new one today: It appears that document.forms[0].cbName.length is null in IE6 (cbName being a hypothetical name for a checkbox) when there is only ONE checkbox with that name. On the BlackBerry browser, however, document.forms[0].cbName.length returns a value of 1.

You might imagine that this (among other things) makes it a challenge to test on IE (faster) for later use on the BlackBerry.

Here is an example of an instance where I had to program for both Browsers just so I could test on IE, even though I was only going to be using this on the BlackBerry:

var df = document.forms[0];
[i]//'ot_cb' is the name of every checkbox, 
// of which there could be one or more.[/i]
if(df.ot_cb.length != null) [i]//if-clause for IE's sake[/i]
{
 for(var i=0; i<df.ot_cb.length; i++)
 {
  if(df.ot_cb[i].checked)
  {
   boxesChecked++;
   df.elements["cb"+boxesChecked].value = df.ot_cb[i].value; 
[i]//interestingly, CANNOT reference checkbox 'id', 
// parameter, so using 'value' instead.  Another 
// BlackBerry JS quirk.[/i]
  }[i]//end if[/i]
 }[i]//end for[/i]
}//end if
else [i]//for the single-checkbox in IE scenario[/i]
{
 if(df.ot_cb.checked)
 {
  boxesChecked++;
  df.elements["cb"+boxesChecked].value = df.ot_cb.value;
 }[i]//end if[/i]
}[i]//end else[/i]

Pretty much, anything I found the BlackBerry could do, IE6 could do as well. This is the first time I had to include JavaScript solely for IE.

Anybody with any experience with the BlackBerry browser? I'm interested in any JavaScript, CSS, and HTML dissimilarities you may have discovered.
