javascript - 'console' is undefined error for Internet Explorer -

-

i'm using firebug , have statements like:

console.log("...");

in page. in ie8 (probably earlier versions too) script errors saying 'console' undefined. tried putting @ top of page:

<script type="text/javascript">     if (!console) console = {log: function() {}}; </script>

still errors. way rid of errors?

try

if (!window.console) console = ...

an undefined variable cannot referred directly. however, global variables attributes of same name of global context (window in case of browsers), , accessing undefined attribute fine.

or use if (typeof console === 'undefined') console = ... if want avoid magic variable window, see @tim down's answer.

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
