我无法理解如何定义具有隔离范围的指令(或内部)使用的函数。在下面的代码中，为什么$scope.foo()函数没有执行？我应该有正确的方法来解决这个问题吗？我希望制作一个仅在用户登录时才可见的按钮，并且认为指令是封装/隔离该功能的好方法。
<!DOCTYPE html>
<html>
<head>
<script src="https://code.angularjs.org/1.4.2/angular.js"></script>
<script>
angular.module('MyApp', [])
.directive('myScopedDirective', function() {
return {
scope: {}, // <!-- isolate scope breaks things
controller: function($scope) {
// isolate scope prevents this function from being executed
$scope.foo = function() {
alert('myScopedDirective / foo()');
};
}
};
});
</script>
</head>
<body>
<div ng-app="MyApp">
<!-- button doesn't work unless isolate scope is removed -->
<button my-scoped-directive ng-click="foo()">directive container - foo()</button>
</div>
</body>
</html>
最佳答案
它不起作用，因为您在不同的范围内使用了 2 个指令:ngClick 和 myScopedDirective。您需要为指令创建一个模板并调用 click 函数，如下所示:
<!DOCTYPE html>
<html>
<head>
<script src="https://code.angularjs.org/1.4.2/angular.js"></script>
<script>
angular.module('MyApp', [])
.directive('myScopedDirective', function() {
return {
restrict: 'AE', // Can be defined as element or attribute
scope: {},
// Call the click function from your directive template
template: '<button ng-click="foo()">directive container - foo()</button>',
controller: function($scope) {
$scope.foo = function() {
alert('myDirective / foo()');
};
}
};
});
</script>
</head>
<body>
<div ng-app="MyApp">
<my-scoped-directive></my-scoped-directive>
</div>
</body>
</html>
