How to recognize PDA

No. It is not possible to specifically test for running on a PDA. You can, however, test whether the user is running on one of the many PDA Operating systems, or using one of the many PDA browsers by detecting the OS and user agent strings:
Code:
alert('User agent string: ' + navigator.userAgent + '\nRunning on OS: ' + navigator.platform);Windows returns "Win32" for the OS string. I have no idea what any of the many PDA OSes return. You'll have to test this yourself (or use Google to search for something like "PDA navigator.platform", etc)
Hope this helps,

The answers you get are only as good as the information you give!
To identify a specific PDA you would need to go to their website to see how they identify themselves as a user agent e.g.
However, since PDAs do not directly support framesets, you could use this as a generic approach:
However, having said that, for any application that contains navigation, a frameset can be ideal.
For example, try this link with a regular browser and then with a PDA.

I have no idea what browsers are available for what PDA OSes, but surely this would be dependant on the browser being used, and nothing at all to do with the actual PDA?

I decided to use a size of screen as indicator because PDA use IE, so it is no other way to recognize it.
But, unfortunately, I found that it not work same as desktop. For instance it not let me show anything i add to body by javascript function on load.

Now that will depend on what onload event you are using.
IE for Win CE does not support the onload event for the body element. It does, however, support the onload event for the window element (as long as you are running IE v4+). Try using that and see how you go.
Hope this helps,

Vadim, Not all PDAs support Javascript.

I guess it depends on which PDA you have.
My blackberry, as configured, will not recognise any script language.
Are you trying to support all PDAs or just some?
