I'm trying to get a simple unhandledrejection handler working in Google Chrome.
If I paste the following code into a JSFiddle and run it in Chrome, I get an error box, as expected:
window.addEventListener('unhandledrejection', function(e) {
console.log(e);
alert(e.reason);
});
new Promise(function(resolve, reject) {
setTimeout(function() {
return reject('oh noes');
}, 2000);
});
If I create an HTML file with an embedded script and load it in Chrome as a file:/// URL, I get a message box, as expected.
<!doctype html>
<html>
<body>
<script type="text/javascript">
window.addEventListener('unhandledrejection', function(e) {
console.log(e);
alert(e.reason);
});
new Promise(function(resolve, reject) {
setTimeout(function() {
return reject('oh noes');
}, 2000);
});
</script>
</body>
</html>
If I create separate HTML and JS files and load it in Chrome as a file:/// URL, I get Chrome's standard 'Uncaught (in promise)' console error but no message box.
index.html:
<!doctype html>
<html>
<body>
<script type="text/javascript" src="app.js"></script>
</body>
</html>
app.js:
window.addEventListener('unhandledrejection', function(e) {
console.log(e);
alert(e.reason);
});
new Promise(function(resolve, reject) {
setTimeout(function() {
return reject('oh noes');
}, 2000);
});
What's going on?

This can be solved by adding crossorigin="anonymous" to the script that is causing unhandled rejection.
<script src="non-default-domain.js" type="text/javascript" crossorigin="anonymous"></script>
