AngularJS 中的路由无法正常工作

Question

我正在尝试 AngularJS.When 中的路由我点击 'li' 2，我想显示 secondScreen.html.Following 的内容是我的 code.I 不知道出了什么问题it.Can 有人告诉我我错过了什么吗？

AngularJS 文件：app.js

var sampleApp = angular.module("sampleApp",['ngRoute','ngResource']);

sampleApp.config(function($routeProvider){

    $routeProvider.when('/',{
        templateUrl : '/templates/firstScreen.html', 
        controller : 'mainController'
    })
    .when('/secondScreen',{         
        templateUrl : '/templates/secondScreen.html', 
        controller : 'mainController'
    })
    .when('/thirdScreen',{          
        templateUrl : '/templates/thirdScreen.html', 
        controller : 'mainController'
    })
    .otherwise({redirectTo : '/'});
});

sampleApp.controller("mainController",["$scope","$log","$resource","$location",function($scope,$log,$resource,$location){

$scope.tabValue = 1;    
$scope.statesAndCapitals = [{state:'Maharashtra',capital:'Mumbai'},{state:'Goa',capital:'Panji'}]

$scope.contacts = [{name:"Steve Jose",mobile : "9872314642",address : "Nasik"}];

$scope.submit = function(tab){
    $scope.tabValue = tab;
    if(tab==1){
        $location.path = '/';
        $log.log("changed path to 1");
    }
    else if(tab==2){
        $location.path = '#/secondScreen';
        $log.log("changed path to 2");
    }
    else if(tab==3){
        $location.path = '#/thirdScreen';
        $log.log("changed path to 3");
    }
}   

$scope.saveContact = function(){

};

}]);

HTML 内容：

<body>
    <div ng-controller="mainController">
        <ul>
            <li ng-click="submit(1)" ng-class="{'btn btn-primary' : tabValue==1,'btn btn-default' : tabValue!=1}">Find Capitals</li>
            <li ng-click="submit(2)" ng-class="{'btn btn-primary' : tabValue==2,'btn btn-default' : tabValue!=2}">Add Contact</li>
            <li ng-click="submit(3)" ng-class="{'btn btn-primary' : tabValue==3,'btn btn-default' : tabValue!=3}">Show Contacts</li>            
        </ul>
    </div>
    <div ng-view></div>
</body>

更改 $location.path.But 后我正在获取日志，但未显示。

这是我的 secondScreen.html :

<div class="container-fluid">   
<form ng-submit="saveContact()">
    Name : <input type="text"><br/><br/>
    Age : <input type="number" min=1 max=150><br/><br/>
    Gender : 
    <input type="radio" ng-model="gender" ng-value="Male">Male<br/>

    <input type="radio" ng-model="gender" value="Female">Female<br/>
    <input type="submit" value="Submit"/>
</form>

使用$location.path('/');

而不是

$location.path="/"
