javascript - angularJS $timeout executing method instantly -


i using ionic framework , cordova-plugin-shake plugin detect device shaking 1 of android application, working fine. problem after shake disable shaking detection 30 second, trying use $timeout this:

$timeout($scope.watchforshake(), 30000);

but somehow $timeout, no matter delay value is, $scope.watchforshake() executed instantly.

i have tried using settimeout result still same.

$timeout (and settimeout) expect callback function first parameter - function execute after time-out.

if want function .watchfortimeout execute, pass function first parameter:

var callbackfn = $scope.watchfortimeout; $timeout(callbackfn, 30000);

after 30 seconds, function callbackfn invoked no parameters: callbackfn().

in case, invoking $scope.watchfortimeout right away, passing return value of function first parameter `$timeout. so, doing (incorrectly) is:

var returnval = $scope.watchfortimeout(); $timeout(returnval, 300000)

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
