I created a custom directive and also have a controller to bind data to the directive.
The data is retrieved from the server and bound to the directive. However, I noticed that the data in the directive on the page does not update when I change the scope variable.
Below is my code:
Directive:
angular.module('MyApp')
.directive('stats',function() {
return {
templateUrl:'scripts/directives/dashboard/stats/stats.html',
restrict:'E',
replace:true,
scope: {
'comments': '@',
'number': '@',
'name': '@',
'colour': '@',
'details':'@',
'type':'@',
'goto':'@'
},
link : function($scope,element,attr){
$scope.$watch('number', function(oldValue,newValue) {
console.log(attr);
}, true);
}
}
});
Directive Template:
<div class="col-lg-3 col-md-6">
<div class="panel panel-{{colour}}">
<div class="panel-heading">
<div class="row">
<div class="col-xs-3">
<i class="fa fa-{{type}} fa-5x"></i>
</div>
<div class="col-xs-9 text-right">
<div class="huge">{{number}}</div>
<div>{{comments}}</div>
</div>
</div>
</div>
<a href="{{goto}}">
<div class="panel-footer">
<span class="pull-left">View Details</span>
<span class="pull-right"><i class="fa fa-arrow-circle-right"></i></span>
<div class="clearfix"></div>
</div>
</a>
</div>
Controller:
'use strict';
angular.module('MyApp',['ngResource'])
.controller('MainCtrl', function($scope,$state,MyService) {
$scope.result = {};
var names = MyService.get({classtype:'getNames',start:'',end:''},function(){
$scope.pages = names.data;
if (typeof($scope.pages[0]) === 'undefined'){
$scope.selectedItem = 'loading...';
}else{
$scope.selectedItem = $scope.pages[0].name;
}
var res = MyService.get({classtype:'getLastRes',seriesName:$scope.selectedItem},function(){
$scope.result = res;
});
});
$scope.dropboxitemselected = function(item){
$scope.selectedItem = item;
var result = MyService.get({classtype:'getLastRes',seriesName:item},function(){
$scope.result = result;
});
//$scope.result = {};
};
});
HTML:
<div class="row" ng-controller="MainCtrl">
<stats number="{{result.score}}" comments="score" colour="primary" type="heartbeat" goto="#/res/{{result._id}}"></stats>
<stats number="{{result.totalSize}}" comments="size" colour="primary" type="file-code-o" goto="#/res/{{result._id}}"></stats>
<stats number="{{result.count}}" comments="count" colour="red" type="file-text" goto="#/res/{{result._id}}"></stats>
</div>
There is a dropdown box on the page which triggers the dropboxitemselected function in the controller to refresh the data in the directive. How can I achieve this?
