I'm coming up to speed with JQM but am a newbie with AJAX. What I'd like to do is dynamically populate a form's text field with data coming from a digital scale, refreshing every few seconds. When the form gets submitted, the currently displayed weight gets inserted into the database via standard form processing.
The scales are on order and I've requested technical info, so I'll need to figure out some of the details when I have the hardware and specs. We will be using PHP on the server side, perhaps the scales can send raw socket data or else output to a text file for processing...
I've done a fair amount of PHP development, but am new to Jquery. What I'd like to do is develop a tablet web app that uses custom image buttons for numeric-only data entry to populate form text boxes.
Basically, when an image button (0 - 9) is tapped by the user, then the text box having the focus gets that corresponding digit added. There will also be a "back" button to erase, and a "send" button to process the form.
It looks like this should be possible to do using Jquery or Jquery UI, but again I'm a newbie with Jquery and am not sure how to proceed. Any advice would be appreciated!
