When using the Javascript API from within a WebView, the following JS exception is raised:
URIError: Domain contained invalid characters.
I found the root cause as well:
There is a RegExp that is ran on "location.hostname" which is an empty string in WebView/UIWebView and the RegExp fails.
The code in the JS SDK (all.js):
function n(o) {
if (typeof o != 'string')
throw new TypeError('The passed argument was of invalid type.');
if (k.test(o))
throw new URIError('The passed argument could not be parsed as a url.');
if (this instanceof n === false)
return new n(o);
var p = o.match(j);
if (!o || !p)
throw new URIError('The passed argument could not be parsed as a url.');
this._protocol = p[4] || location.protocol.replace(/:/, '');
this._domain = p[6] || location.hostname;
this._port = p[8] || (p[6] ? (this._protocol == 'http' ? '80' : '443') : location.port);
this._path = p[9] || '';
this._search = p[11] || '';
this._fragment = p[13] || '';
if (this._path.substring(0, 1) != '/')
this._path = '/' + this._path;
if (!l.test(decodeURIComponent(this._domain.toLowerCase()))) {
i.error('Invalid characters found in domain name: %s', this._domain);
throw new URIError('Domain contained invalid characters.');
}
}
