我想我已经有了一个可行的解决方案。
<!-- links will work as expected where javascript is disabled-->
<a class="intent"
href="http://facebook.com/someProfile"
data-scheme="fb://profile/10000">facebook</a>
我的 javascript 是这样工作的。
注意:其中混合了一些 jQuery,但如果您不想,则无需使用它。
(function () {
// tries to execute the uri:scheme
function goToUri(uri, href) {
var start, end, elapsed;
// start a timer
start = new Date().getTime();
// attempt to redirect to the uri:scheme
// the lovely thing about javascript is that it's single threadded.
// if this WORKS, it'll stutter for a split second, causing the timer to be off
document.location = uri;
// end timer
end = new Date().getTime();
elapsed = (end - start);
// if there's no elapsed time, then the scheme didn't fire, and we head to the url.
if (elapsed < 1) {
document.location = href;
}
}
$('a.intent').on('click', function (event) {
goToUri($(this).data('scheme'), $(this).attr('href'));
event.preventDefault();
});
})();
我也把这个作为gist https://gist.github.com/ChaseFlorell/5119047你可以分叉和搞乱。您还可以包括gist https://gist.github.com/ChaseFlorell/5119047如果你愿意的话,在jsfiddle中。
Edit
@kmallea https://github.com/kmallea分叉了要点并从根本上简化了它。https://gist.github.com/kmallea/6784568 https://gist.github.com/kmallea/6784568
// tries to execute the uri:scheme
function uriSchemeWithHyperlinkFallback(uri, href) {
if(!window.open(uri)){
window.location = href;
}
}
// `intent` is the class we're using to wire this up. Use whatever you like.
$('a.intent').on('click', function (event) {
uriSchemeWithHyperlinkFallback($(this).data('scheme'), $(this).attr('href'));
// we don't want the default browser behavior kicking in and screwing everything up.
event.preventDefault();
});
