angularjs - Destroy angular $http success/error snippets after route change -


the issue can seen here: http://embed.plnkr.co/qcw1ya/

i run route1 , have $timeout function. switch route2, delayed code route1 shows up. want destroy code running in $timeout function, in real case scenario $http service request , shows error messages previous routes.

solution here is: clean after ourselves.

best practices

...

add teardown code controllers , directives
controller , directives emit event right before destroyed. given opportunity tear down plugins , listeners , pretty perform garbage collection.

subscribe $scope.$on('$destroy', ...) event

so, instead of (there a updated plunker)

controller: function($timeout) {     $timeout(function() {       alert("hey i'm message route 1!");     }, 5000) }

we should this:

controller: function($scope, $timeout) {      var removetimer = $timeout(function() {       alert("hey i'm message route 1!");     }, 5000)       $scope.$on('$destroy', function(){       $timeout.cancel(removetimer);        console.log('all cleared')     }); }

not saying - $http has cancel... later or sooner come server...

the point is, if there ghost actions triggered when repsonse comes (inside of .then()) should either clear them or check if state has not gone...

check here

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
