asked Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

here is my

angularroute.html

<html xmlns="http://www.w3.org/1999/xhtml" ng-app="AngularApp">
<head>
    <title></title>
    <script src="angular.js"></script>
    <script src="angular-route.js"></script>
    <script type="text/javascript">

        var AngApp = angular.module('AngularApp', ['ngRoute']);
        AngApp.config(function ($routeProvider) {
            $routeProvider
                .when('/Route1/:ID', {
                    templateUrl:'Route1.html',
                    controller:'Route1'

                })
                .when('/Route2', {
                    templateUrl: 'Route2.html',
                    controller:'Route2'
                })

                .otherwise({
                    redirectTo: '/'
                });
        });

    </script>

            </head>
            <body>

                <p>Routing Explained</p>
                <a href="#Route1/100">Route1</a><br>
                <a href="#Route2">Route2</a>
                <div ng-view>

                <script src="Route.js"></script>       


            </body>
            </html>

the Route.js file contains.

angular.module('Route1').controller('Route1', function ($scope, $routeParams) {
    $scope.ID = $routeParams.ID;
});

angular.module('Route2').controller('Route2', function () {
});

Route1.html

<html xmlns="http://www.w3.org/1999/xhtml" ng-app="Route1">
<head>
    <title></title>

</head>
<body ng-controller="Route1">


    {{ID}}

    {{4+10}}

</body>
</html>

Remove everything that's not needed from your route template. Only the content that you added in your body of the template is required.

That will be included by angular into ng-view with the controller that you have configured in your route. It's a partial and not a complete html file.

Also your route.js code is not correct. You could create a module angular.module('route', []).controller('route1Controller', function(){...}) and use it as dependency in your app.

With-out the brackets like you did in your route.js you're getting a module that's already defined.

Please have a look at your updated code below or in this fiddle.

var AngApp = angular.module('AngularApp', ['ngRoute'])
.controller('Route1Controller', Route1Controller)
.controller('Route2Controller', Route2Controller);

AngApp.config(function ($routeProvider) {
    $routeProvider
        .when('/Route1/:ID', {
        templateUrl:'Route1.html',
        controller:'Route1Controller'

    })
        .when('/Route2', {
        templateUrl: 'Route2.html',
        controller:'Route2Controller'
    })

        .otherwise({
        redirectTo: '/'
    });
});

function Route1Controller($scope, $routeParams) {
    $scope.ID = $routeParams.ID;
}

function Route2Controller($scope) {

}

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.7/angular-route.js"></script>

<div ng-app="AngularApp">
    <script type="text/ng-template" id="Route1.html">
        Route1
        {{ID}}

        {{4+10}}
    </script>
    <script type="text/ng-template" id="Route2.html">
        Route2

        {{4+10}}
    </script>

                <a href="#Route1/100">Route1</a><br/>
                <a href="#Route2">Route2</a>
                <div ng-view>

                </div>
    </div>
