Injecting javascript is too slow

[0xWDG]

If i set the url to http://wdg.github.io/HTML-iOS-Template/mac.html
wich contains a test what uses window.webshell.version a.k.a. webshell.version.
i'd need to create a hack because the injecting is somewhat to slow.

The function:

function myFunction() {
    if (typeof window.webshell !== 'undefined') {
        console.log(window.webshell.version) // works...
    } else {
        console.error('i\'m missing something')
    }
}

the hack:

rdy(function(){myFunction()});
function rdy(f){/in/.test(document.readyState)?setTimeout('rdy('+f+')',9):f()}

this test every 9ms the readyState.

because window.addEventListener is too fast, and injecting to slow.

window.addEventListener(
    "load",
    function(event) { myFunction() },
    true
); // missed it, to early

window.addEventListener(
    "load",
    function(event) { myFunction() },
    false
); // missed it, to early

window.addEventListener(
    "DOMContentLoaded",
    function(event) { myFunction() }, 
    true
); // missed it, to early

window.addEventListener(
    "DOMContentLoaded",
    function(event) { myFunction() },
    false
); // missed it, to early

Possible solutions:

• Try to inject the javascript faster.
• Extend WebKit (don't know if it is possible, in this way)
• Fire the DOMContentLoaded, load 2 times (last time by WebShell)
