我正在尝试在页面加载时动态设置页面标题。这是我的代码:

<!DOCTYPE html>
<html ng-app="myApp">
<head>
    <meta http-equiv="content-type" charset="utf-8" />
    <title ng-bind="title"></title>
    <style type="text/css">
        [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
            display: none !important;
        }
    </style>
</head>
<body style="font-family:sans-serif" ng-controller="clicks">

    <h1>Hello <span ng-cloak class="ng-cloak">{{ user.name }}</span></h1>
    <input type="text" ng-model="user.name" placeholder="Enter a name here" >

    <h2>Clicked {{ counter.clicks }} times</h2>
    <button ng-click="count()" >Click</button>

    <script src="vendor/angular/angular.js"></script>
    <script>
        angular.module("myApp", ["myApp.controllers"]);

        angular.module("myApp")
            .run(function($rootScope) {
                $rootScope.title = "Angular Learning 1";
            });

        angular.module("myApp", [])
            .controller("clicks", function($scope) {
                $scope.user = {
                    name: "Sithu"
                }
                $scope.counter = { clicks: 0 };
                $scope.count = function() {
                    $scope.counter.clicks += 1;
                }
            });
    </script>
</body>
</html>

我认为在$rootScope.title中设置run()可以更新页面加载中的标题,但事实并非如此。

它不适合您,因为在使用myApp声明控制器时覆盖整个angular.module("myApp", [])模块。这是setter语法,但是你需要getter来检索已经创建的模块。

正确的代码是:

angular.module("myApp")
// Note no [] here --^
    .controller("clicks", function($scope) {
        $scope.user = {
            name: "Sithu"
        }
        $scope.counter = {
            clicks: 0
        };
        $scope.count = function() {
            $scope.counter.clicks += 1;
        }
    });

你可以改进的另一件事。标题不需要ngBind,不需要再绑定一个。只需设置document.title

即可
.run(function() {
    document.title = "Angular Learning 1";
});
