我尝试在 AngularJS 控制器初始化中调用 dart 函数,但我得到ReferenceError: myFunction is not defined
.
索引.dart
import 'dart:js';
myDartFunction() {
return 42;
}
main() {
context['myFunction'] = (JsObject exchange) {
exchange['output'] = myDartFunction();
};
}
我的 AngularJS 的 html:
<!DOCTYPE html>
<html ng-app="MyApp">
<head lang="en">
<meta charset="UTF-8">
<title>My Title</title>
</head>
<body>
<div ng-controller="MyCtrl">
<p>{{var}}</p>
</div>
<script type="application/dart" src="index.dart"></script>
<script type="application/javascript" src="../packages/browser/dart.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.js"></script>
<script>
angular.module("MyApp", []).controller('MyCtrl', function($scope) {
var exchange = {};
myFunction(exchange);
$scope.var = exchange['output'];
});
</script>
</body>
</html>
在我看来,context['myFunction']
控制器初始化时尚未设置。我怎样才能等待它并初始化$scope.var
?
