javascript - angular directive scope not binding data -


i have question, code this:

html:

<div class="overflow-hidden ag-center" world-data info="target"></div>

js:

.directive('worlddata', ['$interval', function($interval) {     return {         scope: {             chart: '=info'         },          template: '<div>{{chart.aaa}}</div>',          link: function($scope, element, attrs) {              $scope.target = {'aaa': 'aaa'};              aaa = $scope.chart;         }     } }])

the chart value undefined, , template no value, when declare $scope.target within controller, code works, why?

this should pattern:

.controller('mycontroller', function($scope){     $scope.target = {'aaa': 'aaa'}; //in reality, you'd load via other method, $http. })  .directive('worlddata', [function() {     return {         scope: {             chart: '=info'         },          template: '<div>{{chart.aaa}}</div>'      } }])

--

<div ng-controller="mycontroller">     <div class="overflow-hidden ag-center" world-data info="target"></div> </div>

alternatively, directive responsible going , fetching data, , not pass in it. you'd want consider if don't need data in multiple places.

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.
