Question

尝试做一些DOM操作，但永远不会调用link()，所以没有任何反应：

app.js

var app = angular.module('app', ['directives', ...]);
var directives = angular.module('directives', []);
...

directives.js

directives.directive('doIt', ['$window', function($window) {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            console.log('Inside link()');
            // Do stuff with $window
        }
    };
]});

HTML

<html ng-app="app">
    <body>
        <div ng-view>
            <div do-it>
                // ....
            </div>
        </div>
    </body>
</html>

我错过了什么？

Answer 1

方括号不正确

directives.directive('doIt', ['$window', function($window) {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            console.log('Inside link()');
            // Do stuff with $window
        }
    };

    }]);//Check this part. The square bracket was on the wrong side of }

像上面的那样移动它

您的模块声明中还有一些额外的句号

var app = angular.module('app', ['directives']); //删除额外....的

这是plnkr的帮助吗？plnkr

 angular.module('app', [])
// .controller('Controller', ['$scope', function($scope) {
//   $scope.customer = {
//     name: 'Naomi',
//     address: '1600 Amphitheatre'
//   };
// }])
.directive('doIt', ['$window', function($window) {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
        console.log('Inside link()');
        // Do stuff with $window
    }
  };
}]);

AngularJS指令DOM操作不执行link（）
