how to prevent iOS safari alert when trying to open non-installed native app?

Question

I\'ve been looking for a way to open a native iOS app from the browser. I found a decent solution here: Is it possible to register a http+domain-based URL Scheme for iPhone

For solving this and avoid no wanted iOS safari alert I've used a different approach handle also an iframe but without jquery and listener events. It works perfectly.

    var iframe = document.createElement("iframe");

    iframe.style.border = "none";
    iframe.style.width = "1px";
    iframe.style.height = "1px";
    iframe.onload = function () {
        document.location = alt;
    };
    iframe.src = nativeSchemaUrl; //iOS app schema url

    window.onload = function(){
        document.body.appendChild(iframe);
    }

    setTimeout(function(){
        window.location = fallbackUrl; //fallback url
    },300);
