Dans keyboardJS.init(), vous utilisez la méthode bind() sur votre callbacks événement.
document.addEventListener("keydown", this.keyIsDown.bind(this));
document.addEventListener("keyup", this.keyIsUp.bind(this));
Safari (y compris Safari mobile) ne prend pas en charge la liaison () méthode.Vous devez fournir un polyfill:

if (Function.prototype.bind === null || Function.prototype.bind === undefined) {
Function.prototype.bind = (function (slice) {
// (C) WebReflection - Mit Style License
function bind(context) {
var self = this; // "trapped" function reference
// only if there is more than an argument
// we are interested into more complex operations
// this will speed up common bind creation
// avoiding useless slices over arguments
if (1 < arguments.length) {
// extra arguments to send by default
var $arguments = slice.call(arguments, 1);
return function() {
return self.apply(
context,
// thanks @kangax for this suggestion
arguments.length ?
// concat arguments with those received
$arguments.concat(slice.call(arguments)) :
// send just arguments, no concat, no slice
$arguments
);
};
}
// optimized callback
return function() {
// speed up when function is called without arguments
return arguments.length ? self.apply(context, arguments) : self.call(context);
};
}
// the named function
return bind;
} (Array.prototype.slice));
}
Oh, monsieur! Beaucoup de félicitations pour cela! Il fonctionne parfaitement! :) –
