javascript - AngularJS Directive element method binding - TypeError: Cannot use 'in' operator to search for 'functionName' in 1 -


this controller of main template:

app.controller('overviewctrl', ['$scope', '$location', '$routeparams', 'websiteservice', 'helperservice', function($scope, $location, $routeparams, websiteservice, helperservice) {     ...          $scope.editwebsite = function(id) {         $location.path('/websites/edit/' + id);     }; }]);

this directive:

app.directive('wdawebsitesoverview', function() {     return {         restrict: 'e',         scope: {             heading: '=',             websites: '=',             editwebsite: '&'         },         templateurl: 'views/websites-overview.html'     } });

this how directive applied in main template:

<wda-websites-overview heading="'all websites'" websites="websites" edit-website="editwebsite(id)"></wda-websites-overview>

and method called directive template (website-overview.html):

<td data-ng-click="editwebsite(website.id)">edit</td>

question: when edit clicked, error appears in console:

typeerror: cannot use 'in' operator search 'editwebsite' in 1

does know goes on here?

since defined expression binding (&), need explicitely call json containing id if want bind in html edit-website="editwebsite(id)".

indeed, angular need understand id in html, , since not part of scope, need add called "locals" call doing:

data-ng-click="editwebsite({id: website.id})"

or alternative:

data-ng-click="onclick(website.id)"

with controller/link code:

$scope.onclick = function(id) {   // ad "id" locals of "editwebsite"    $scope.editwebsite({id: id}); }

this documented here, example involving "close({message: 'closing now'})"

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.
