Launch App from browser

[Sagi]

I'm trying to launch my app in case it is installed and fallback to my website if tbe the app does not exist. (got some insights from  : http://stackoverflow.com/questions/13044805/how-to-check-if-an-app-is-installed-from-a-web-page-on-an-iphone

I was able to launch the app using custom url scheme , but was only able to so when there is user interaction (e.g. user clicks a button/link) :

     <a onclick="window.open('myapp://foo=bar', '_system')">Launch myapp</a>


However When using 

  window.open('myapp://foo=bar', '_system');

or 

 window.location = 'myapp://foo=bar'

without user interaction (e.g. on window load / document ready) the app does not launch.

Is this expected ?

Any workarounds ?

Thanks

Hello Sagi,

I am afraid the case you are describing cannot be achieved due to browser restrictions. Attempting to invoke window.open without user interaction(click event) will be blocked by the browser for security purposes.

This being said, I am not aware of any workarounds you can use to reach the desired effect. Please have in mind that even if a workaround exists it will most likely be browser-specific and not a general solution.

I hope this helps.
