ng-click功能立即执行功能而不点击

我是角色新手并试图设置登录系统。我有一些按钮'设置为在单击按钮时将用户重定向到用户facebook / google帐户的Oauth提示。我的问题是记录用户的功能是在页面日志上立即执行,而不是在单击按钮时执行。

我很确定根源在于JS对象的工作方式,但我仍在学习angularjs,这有点令人困惑。

我相信将函数放在$ scope上会立即执行它们,但我不知道如何将它们暴露给ng-click。

有人可以帮我解决如何让按钮按预期工作吗?

模板:

<ion-view title="Account">
    <ion-nav-buttons side="right">
        <button menu-toggle="right" class="button button-icon icon ion-navicon"></button>
    </ion-nav-buttons>
    <ion-content class="has-header padding">

        <h1 ng-click="google_login()">Log in with Google</h1>
        <h1 ng-click="fb_login()">Log in with Facebook</h1>
        <h1 ng-click="dev_login()">Dev login</h1>
        <div id="logs"></div>
        <form class="list">
            <label class="item item-input">
                <input type="text" placeholder="Username" ng-model="user.username" required>
            </label>
            <label class="item item-input">
                <input type="password" placeholder="Password" ng-model="user.password" required>
            </label>
            <div class="padding">
                <button class="button button-block button-stable" ng-click="email_authenticate()">Login</button>
            </div>
        </form>
    </ion-content>
</ion-view>

控制器:

.controller('AccountCtrl', function($scope, $state, Authentication) {
    $scope.dev_login = Authentication.dev_authenticate(); //executes immediately
    $scope.fb_login = Authentication.fb_authenticate(); //executes immediately
    $scope.google_login = Authentication.google_authenticate(); //executes immediately
    $scope.email_login = Authentication.email_authenticate(); //executes immediately
    $scope.logout = Authentication.logout();
});

这些在services.js中定义:

.factory('Authentication', function ($http) {
    return {
        authenticate: function () {
            return $http({
                url: 'https://api.squawkfinace.com/authenticate',
                method: 'post'//,
                //data: {facebook_authtoken: key}
            });
        },
        fb_authenticate: function () {
            return $.oauth2({
                 //Oauth details
            }, function (token, response) {
                localStorage.setItem("LoggedInAccount", JSON.stringify({'platform': 'facebook', 'token': token}));
                console.log(token);
                $state.transitionTo("app.notifications");
            }, function (error, response) {
                // do something with error object
            });
        },
        google_authenticate: function () {
            return $.oauth2({
                //oauth details
            }, function (token, response) {
                localStorage.setItem("Account", JSON.stringify({'platform': 'google', 'key': token}));

            }, function (error, response) {
                // do something with error object
                $("#logs").append("<p class='error'><b>error: </b>" + JSON.stringify(error) + "</p>");
                $("#logs").append("<p class='error'><b>response: </b>" + JSON.stringify(response) + "</p>");
            });
        },
        dev_authenticate: function () {
            return null;
        },
        email_authenticate: function () {
          return null;
        },
        logout: function () {
            localStorage.removeItem("Account");
            return null;
        }
    }
});

答案 0 :(得分:2)

这是因为你实际上正在执行这些功能

$scope.dev_login = Authentication.dev_authenticate();

应该是

$scope.dev_login = Authentication.dev_authenticate;

第一个场景执行该函数并将结果分配给$ scope。您想要为该函数分配引用。
