Question

我正在尝试使用angularJS构建动态菜单，遗憾的是它不起作用，我不知道为什么。有什么想法吗？

我的想法是：我将遍历当前控制器实例的menuItem集合。 item的name属性将显示为menuItem名称，menuItem的path属性将作为参数传递给nagivate（）函数。

var clientParams = {
    appKey: "....."
    , appSecret: "....."
};

var app = angular.module("helloKinveyApp", ["ngRoute", "kinvey"]);

app.config(["$routeProvider", function($rootProvider) {
    $rootProvider
        .when("/", {
            controller: "loginController"
            , templateUrl: "app/partials/login.html" })
        .when("/partials/password_reset", {
            controller: "resetPasswordController"
            , templateUrl: "app/partials/password_reset.html" })
        .when("/partials/sign_up", {
            controller: "signupController"
            , templateUrl: "app/partials/sign_up.html" })
        .when("/partials/logged_in", {
            controller: "loggedInController"
            , tempalteUrl: "app/partials/logged_in.html" })
        .otherwise({ redirectTo: "/"});
}]);

app.run(["$location", "$kinvey", "$rootScope", function($location, $kinvey, $rootScope) {
    var promise = $kinvey.init({
       appKey: clientParams.appKey
        , appSecret: clientParams.appSecret
    });
    
    promise.then(function() {
        console.log("Kinvey init with success");
        determineBehavior($location, $kinvey, $rootScope);
    }, function(errorCallback) {
        console.log("Kinvey init with error: " + JSON.stringify(errorCallback));
        determineBehavior($location, $kinvey, $rootScope);
    });
}]);

function determineBehavior($location, $kinvey, $rootScope) {
    var activeUser = $kinvey.getActiveUser();
    console.log("$location.$$url: " + $location.$$url);
    
    if (activeUser != null) {
        console.log("activeUser not null, determine behavior");
        
        if ($location.$$url != "/partials/logged-in")
            $location.path("/partials/logged-in");
    }
    else {
        console.log("activeUser null redirecting");
        
        if ($location.$$url != "/partials/login")
            $location.path("/partials/login");
    }
}


'use strict';
app.controller("loginController", function($scope, $kinvey, $location) {
    $scope.menuItems = [
        {name: "Pricing", path: "#"}
        , {name: "Customers", path: "#"}
        , {name: "Help", path:"#"}
        , {name: "Sign up", path: "#"}
    ];
    
    $scope.signin = function($scope, $kinvey, $location) {
        alert("signin()");
    };
    
    $scope.signup = function($scope, $kinvey, $location) {
        alert("signup()");
    };
    
    $scope.forgotPassword = function($scope, $kinvey, $location) {
        alert("forgotPassword");
    }
    
    $scope.navigate = function (path2Navigate) {
        alert(path2Navigate);
    }
});

您在<ul>标记上使用了ng-repeat，这会为您的菜单数组中的每个项目生成<ul>。在<li>上使用它，以便每个菜单项都是菜单项而不是空菜单。

您也不需要在item.path中包裹{{}}。当你以角度开始时，这是一个常见的错误。将其更改为data-ng-click="navigate(item.Path)"我也没有看到您在HTML中的任何位置使用loginController。试试<header class="container" ng-controller="loginController">

AngularJS无法生成动态菜单
