javascript - ng-init vs function in controller, which is better practice when using $parent? -


i have bootstrap modal corresponds ng-repeat list. access ng-repeat scope data parent, contains modal. when modal button clicked on list, corresponding data json appears in modal.

i have found 2 ways of doing this, , wonder best alternative?

method 1 view:

<li ng-init="myfunction(item,$parent)" ng-repeat="item in data.webapps_1.items>

controller:

 $scope.myfunction = function(item,parent){         parent.selected=item.counter-1;     };

method 2 view:

<li ng-init="$parent.selected=item.counter-1" ng-repeat="item in data.webapps_1.items>

with nothing in controller.

i have read in angular nginit docs

the appropriate use of nginit aliasing special properties of ngrepeat, seen in demo below. besides case, should use controllers rather nginit initialize values on scope.

but list of special properties of ngrepeat not include $parent.

so, better practice? including expression $parent.selected=item.counter-1in controller or in nginit directive?

thanks in advance

either of 2 fine really, long you're consistent. depends on scale of app though.

imo if app going large you'll want go function way, better adhere whole mvc philosophy of decoupling , separation of concerns (http://victorblog.com/2013/03/18/angularjs-separation-of-concerns/).

ng-init="myfunction(item,$parent)"

it's better structure because want keep of business logic in javascript controllers, not in view.

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.
