I have a main controller in which i want to emit/ broadcast an event
main controller
.controller('gameCtrl', function(){
function moveToTileBy(moves)
{
var numberOfTiles = ctlr.board.tiles.length,
player = getCurrentPlayer(),
currentTileNumber = player.currentPositionTileNumber;
if((moves + currentTileNumber) > numberOfTiles)
{
// alert player not enough moves
return nextTurn();
}
// create a drag and drop
$scope.$emit('movePlayer', currentTileNumber);
$scope.$emit('activateTile', moves + currentTileNumber);
}
})
I also have a directive on an ng-repeat
items, each item has an isolated scope whose only connection to the main controller is the scope's model
directive
.directive('phTile', ['$rootScope', 'Drake', function ($rootScope, Drake) {
return {
restrict: 'A',
scope: {
tile: '@ngModel'
},
link: function (scope, element, attr) {
var elem = element[0];
console.log(scope.tile);
$rootScope.$on('movePlayer', function(){
console.log('root link move player ', arguments);
});
scope.$on('movePlayer', function(){ console.log('link scope move player', arguments);})
}
};
html
<div ng-controller="gameCtrl as ctlr">
<div ng-repeat="(i, tile) in ctlr.board.tiles" class="w3-col tile tile-{{tile.number}}" ng-repeat-end-watch="ctlr.resize()" ng-model="tile" ph-tile><span>{{tile.number}}</span></div>
</div>
I want the above event in the controller to trigger a series of dom manipulations to 1 or more item DOM elements
The dilemma i am facing is that I am not sure how/ where to build the logic to listen to the said event and proceed with the logic for dom manipulation....
Should it be
1) In a directive controller
return {
restrict: 'A',
scope: {
tile: '=ngModel'
}, controller: function($scope){ $scope.$on('move', function(){ /* manipulate dom element */}); }
2) Or in the link
return {
restrict: 'A',
scope: {
tile: '=ngModel'
}, link: function(scope, element, attr){ scope.$on('move', function(){ /* manipulate dom element */}); }
In addition I need to access the isolated scope's "tile" object and the directive's "element" in order to proceed with the dom manipulation.
