Would be nice if it asks height in feet and inches and weight in lbs.

[palmdoc2005]

er.. the ROW uses SI units

[whitesmoke33]

well done! i am getting tired of running skyscape and pepid on classic

we need more medical WebOs stuff....great start!

[cohoman]

I agree, in that the "Rough Cuts" book is pretty dry reading and the first example was way too complicated. So, what issues do you have with your sample application?

[majikTib]

just a suggestion (as I won't be using this)... what if you had it automatically convert from inches to cm? That may reduce human error, or at least verify what you had calculated.

Input inches, Output cm
Input pounds, Output kg

I don't know how to put the JS code in the assistant section to work with the regular html in the views/scene section, and I hope some kind soul will be able to help.
I'm now checking this clearer tutorial out
First official webOS / Mojo SDK Tutorial from Palm Redux!
and wonder why Mitch didn't put this in the book

Yes that can be easily done, but my priority is to learn to "properly" place the code

Being in the healthcare field myself, you don't always get the numbers you are looking for. Once you get the hang of this, it might be better for you to have a tab or something to switch between British and Metric units and the conversion is made for you. This is just an idea when you are ready for that. I'll be learning how to do this in the future once I'm done with school because there are some things that I'll need as well. When I did my dietetic internship clinical rotation, I made a spreadsheet to calculate energy needs and BMI. I had it on my Palm Tungsten E2 as well as in my Google Docs for me to use. I still have a while before I'll have the time for programming. Keep up the good work though. Mediquations is looking into a Pre app. Their iPhone one is really awesome.

[cohoman]

I took your index.html file and tuned it up using some basic CSS and made a slight change to the javascript routine you created. For this app, you can make the calculation and display the results all on one page. If you want to jump to other pages ("scenes"), use customer list controls, etc. then you'll need to add some Mojo Javascript coding to the assistant.js file, etc. That's when things get complicated...

Attached should be the modified index.html file and the packaged ipk file that I created.

[palmdoc2005]

Thanks cohoman. I've learnt a couple of new things about Javascript today
-document.getElementById
- innerHTML

I've modified the attachments in the first post
I guess the normal Javascript Alert function does not work?
Looks like these have to go into mojo dialogue controls, sigh

Now to delve deeper into how to get all of these into the assistants and scenes....

[cohoman]

You are right, in that the Javascript alert() function does not display a popup message.

I'm debating whether to develop my apps using basic Javascript techniques, or struggling through the Mojo Framework controls. Mojo will be tough to swallow, so I'll have to try both methods and see which works better.

Good luck with your Med Apps.

You should also learn about the prototype library.

$("bsaResults").update('Body Surface Area = ' + bsa + ' m2');

I'd highly recommend using the Mojo functions. The various alerts are pretty straightforward to use.

/unless you don't have access to the API, in which case the Prototype suggestion is a good one.

Hey cool! Learnt one more thing today!.
I went through the samples including Buttons, UIWidgets, Text fields etc. and it is very confusing
My apps have a simple structure

1) Data input in terms of text/numeric entry in text fields or drop down boxes
2) A button to submit the data
3) A simple calculation to compute the data
4) Output the result

The best way to learn I think is by example as all the tutorials on the web and sample code including the homebrew ones so far don't quite fit or are too complicated (for me at least)
Can anyone help changing the BSA app from plain JS to using Mojo functions? Thanks

[bkcrown]

Thank you for initiating the first app for Palm Pre. I really need to use Sprint (horrible AT+T coverage in my area) and I dearly miss my multiple old Palm OS apps.

Greatly appreciate you jumping in.

There's always Classic

[h3artl3ss]

We need more apps like this.

[palmdoc2005]

Still learning. From rboatright's suggestion on "mojo-ization", I moved the html in the body to a scene, and just moved out the JS code to the end of the scene assistant as suggested here:
pre dev wiki: Porting Older Apps

and it still works.

Now to figure out how the mojo widgets work. Ugh.

[palmdoc2005]

First post updated.
I have basically made it more mojo-like by moving the code to the assitant/views format and the buttons are WebOS style. I basically modified the HelloWorld tutorial

I can't get the ViewRef button to work with as a simple pop-up Error Dialog. After looking at the UIWidget sample, I thought it might work as a
Mojo.Controller.errorDialog(...)

Grateful for any pointers here. Thanks.

Further to dos:
A toggle button to switch to and fro from SI to Imperial units.
