第一种使用 ng-controller="cntrl as vm" 语法的方法:
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script>
angular.module('MyApp', [])
.controller('MyCntrl', function($scope) {
var vm = this;
vm.name = 'Custom Directive';
});
</script>
<body>
<div ng-app="MyApp" ng-controller="MyCntrl as vm">
{{vm.name}}
</div>
</body>
</html>
第二种方式使用 controllerAs 作为指令的属性之一:
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script>
angular.module('MyApp', [])
.directive('customDir', function() {
return {
restrict: 'EA',
template: '<div>{{vm.name}}</div>',
controller: function(){
var vm = this;
vm.name = 'Custom Directive';
},
controllerAs: 'vm'
}
});
</script>
<body>
<div ng-app="MyApp">
<div custom-dir></div>
</div>
</body>
</html>
使用在控制器中定义但在 html 中调用的“控制器为”语法调用函数的方法:
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script>
angular.module('MyApp', [])
.controller('MyCntrl', function($scope) {
var vm = this;
vm.name = 'Custom Directive';
vm.someFunction = function() {
vm.name = 'Button is Clicked!!!';
};
});
</script>
<body>
<div ng-app="MyApp" ng-controller="MyCntrl as vm">
{{vm.name}}
<input type='button' ng-click="vm.someFunction()" value="Click" />
</div>
</body>
</html>
