我有以下html
<div ng-controller="select">
<select ng-options="n for n in names"
ng-model="selected.item"
ng-change="change()">
</select>
</div>
<div ng-controller="graph">
<input type="text" ng-model="mySelected.item">
<canvas id="line" class="chart chart-line" chart-labels="gs" chart-data="ser">
</canvas>
</div>
我希望ng-option中的change()方法调用“graph”控制器。基本上,如果选项被更改,则应更新图表。有没有办法做到这一点。请帮忙。
如果需要,我也会分享我的控制器代码:`
app.controller('graph', ['$scope', '$http', 'myService', function($scope,$http, myService) {
$scope.mySelected = myService.selected;
console.log($scope.mySelected);
//$http.get('/myapp/stocklist/'+ $scope.mySelected).
$http.get('/myapp/stocklist/AMZN').
success(function(data) {
gs = [];
ser = [];
for( var i=0; i<data.length; i++ ) {
gs.push(data[i].name);
ser.push(data[i].high);
}
$scope.gs=gs;
$scope.ser=[];
$scope.ser.push(ser);
});
}]);
app.controller('select', ['$scope', '$http', 'myService', function($scope,$http, myService) {
$scope.selected = myService.selected;
$http.get('/myapp/stocknames').
success(function(data) {
$scope.names=data;
console.log($scope.names);
});
}]);
答案 0 :(得分:0)
在图形控制器中,您将使用$ on:
scope.$on('onServiceSelected', function (event, selectedService) {
$scope.mySelected = selectedService;
});
在您的其他控制器中,您将使用$ broadcast:
$rootScope.$broadcast('onServiceSelected',$scope.serviceSelection);
这应该指向正确的方向。
