Detecting if a form is open on Mobile or Desktop





I have a form that works perfectly on Desktop, but the submit button don’t works on mobile. I know it’s because I have a custom javascript inside that button and only a portion of javascript is supported on mobile device.  
  
My question is: Is there a way to have something inside the PDF that can detect if the PDF is open on desktop versus mobile, and change the submit mecanism according to each?  
  
Thanks!
Not likely. If a script can't work, then it also can't detect that it's not working... The workaround is to create a warning message that's always visible by default and then use a script to hide it (for example, by making a field that's placed on top of it hidden). If the script executes, the message is hidden when the file is opened. If it's not, the message remains visible.
You can detect the browser in use and display the message. You can even have it hide the page content unless the browser used is Internet Explorer. However, there's no way to use JavaScript (or any other web dev. code) to open a completely separate program.



If you are really determined, you might try looking into something that indirectly opens another program through an object or applet of some kind, like flash or Java applets. I don't think you'll find anything, though.



If this were possible, it would be a security problem. Consider the situation if IE had a known exploit and it were possible to force a page to open in IE regardless of the browser it was originally opened in.



I recommend fixing your site. It's not that difficult to develop pages that work everywhere. If I develop pages in accordance with the W3C recommendations, they work pretty well in Firefox, Safari, Opera, and Chrome. Then it's not too difficult to tweak them to work in IE. I've found that doing it the other way around, targeting IE first then tweaking it to work in other browsers, is much more difficult. Pages that require Microsoft ActiveX plugins are an exception of course, but I think it's well worth the time to find an alternative.

but yeah a pdf reader only lets you read pdfs or fill out pdf forms. a productivity suite is usually only things like word and excel microsoft office.

a pdf editor, i.e. adobe acrobat, lets you actually make pdfs from scratch, and do things like add in typable boxes so you can make forms people can fill out and print or save and send off. (like a job application or a medical waver or something) this is much easier to do than it sounds. if you have adobe pdf reader downloaded and installed in some format on your computer, all you have to do is follow a few quick instructions. first, you open the pdf in adobe. then, you click Hi. Yes the mobile application option is offline. Find the alternative here <http://satechhelp.co.za/6596/Loan-Sassa-Social-Grant-Beneficiery> hi marko :slight\_smile: welcome to the community.

if you use multiple devices, it makes sense to enable “send copy to yourself” everywhere, so you see your own messages on all devices: <https://delta.chat/en/help#what-is-the-send-copy-to-self-setting-good-for>

ios often stops delta chat from running… i just figured out what the problem was. if you enable the “titlebar” in firefox’s “customize…” window (it is a checkbox at the bottom) then the traditional window titlebar appears (with the buttons on the left) and the click and drag thing works. who knew? hi roland, the universal gui will ultimately become a fully-fledged alternative to the windows, web and mobile user interfaces. we will make sure that current layouts (with tabs and inline details) in windows and web are also supported in the universal gui, to make the transition as smooth as possible! 介紹你使用「pdf split and merge 」這款軟體！

post code header, footer and other page attributes are stored against “sections” and not individual pages. each section can be one page, several pages or the entire document. inserting a manual page break starts a new section. i am new to libreo and was also frustrated by its behaviour till the penny dropped …
