Execute code if native app not exists in javascript

Question

I want to display a popup if instagram is not installed. I have this code right now:

setTimeout(function () { 
            $.mobile.changePage( "dialog-instagram.html", { role: "dialog" });
}, 5);
window.location = "instagram://media?id=" + element.title;

If instagram is installed on mobile phone, this launch the app and shows the photo I want. If not installed, launch dialog-instagram.html

Thanks ok. The problem is that dialog-instagram.html is always launched. I just want it to launch if app is not opened. I understand why, code is launched with 5 seconds of delay.

Can that be done? How can I know if window.location is succesful or not?

Try increasing the delay time is very short, so you can try increasing it (300ms would be something reasonable). If that doesn't work, try this code (based on this answer):

function startIThrown(){
  document.location = 'instagram://media?id=' + element.title;
  setTimeout(function(){
    if(confirm('You do not seem to have iThrown installed, do you want to go download it now?')){
      document.location = 'http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=293049283&mt=8&uo=6';
    }
  }, 300);
}

<a href="#" onclick="startIThrown()">Restart iThrown</a>

At the end I haven't found a way to solve it. When you return from native app, you see the message. – Biribu Jul 17 '14 at 10:52
