带有ng-click的AngularJS登录表单不起作用 [英] AngularJS Login form with ng-click not working

问题描述

我在这个 plunk 中写了一个基本的登录表单 http://plnkr.co/edit/xQEN1ZNN5ZEw1CSwNw97?p=preview(点击 Home 路径上的红色 Log into Dashboard 按钮).

I wrote a basic login form in this plunk http://plnkr.co/edit/xQEN1ZNN5ZEw1CSwNw97?p=preview (click on the red Log into Dashboard button on the Home route).

但是由于某种原因，我无法在我的 loginCtrl 控制器代码中触发 login() 方法.

However for some reason I cannot get the login() method to fire in my loginCtrl controller code.

为什么这个例子有效，而我的无效?http://plnkr.co/edit/H4SVl6?p=preview

Why is this example working, and mine is not ? http://plnkr.co/edit/H4SVl6?p=preview

相反，它所做的是一个老式的 URL 重定向，其中用户/密码参数作为表单变量传入.我不知道出了什么问题.

Instead what it's doing is an old-school URL redirect with the user/password parameters passed in as form variables. I can't figure out what's wrong.

这里是 LoginCtrl 代码以及 login-form.html 模板:

Here is LoginCtrl code as well as the login-form.html template :

(function () {
    'use strict';

    angular.module('routerApp').controller('LoginCtrl',
        ['$rootScope', '$scope', authenticate]);

    function authenticate($rootScope, $scope,   userService) {

        var login = this;

        login.loginUser = function () {
            login.dataLoading = true;
            //loginService.authUser(login.user, login.password);  // TO DO !!!
        };
        login.test = function () {
            var test = true;
        };
    }
})();

<div ng-show="error" class="alert alert-danger">{{error}}</div>
<form  ng-submit="login.loginUser()" name="form">
    <div class="form-group">
        <label for="username">Username</label>
        <i class="fa fa-key"></i>
        <input type="text" name="username" id="username" class="form-control" ng-model="login.username" required />
        <span ng-show="form.username.$dirty && form.username.$error.required" class="help-block">Username is required</span>
    </div>
    <div class="form-group">
        <label for="password">Password</label>
        <i class="fa fa-lock"></i>
        <input type="password" name="password" id="password" class="form-control" ng-model="login.password" required />
        <span ng-show="form.password.$dirty && form.password.$error.required" class="help-block">Password is required</span>
    </div>
    <div class="form-actions">
        <button type="submit" ng-disabled="form.$invalid || dataLoading" class="btn btn-danger">Login</button>
        <img ng-if="login.dataLoading" src="data:image/gif;base64,R0lGODlhEAAQAPIAAP///wAAAMLCwkJCQgAAAGJiYoKCgpKSkiH/C05FVFNDQVBFMi4wAwEAAAAh/hpDcmVhdGVkIHdpdGggYWpheGxvYWQuaW5mbwAh+QQJCgAAACwAAAAAEAAQAAADMwi63P4wyklrE2MIOggZnAdOmGYJRbExwroUmcG2LmDEwnHQLVsYOd2mBzkYDAdKa+dIAAAh+QQJCgAAACwAAAAAEAAQAAADNAi63P5OjCEgG4QMu7DmikRxQlFUYDEZIGBMRVsaqHwctXXf7WEYB4Ag1xjihkMZsiUkKhIAIfkECQoAAAAsAAAAABAAEAAAAzYIujIjK8pByJDMlFYvBoVjHA70GU7xSUJhmKtwHPAKzLO9HMaoKwJZ7Rf8AYPDDzKpZBqfvwQAIfkECQoAAAAsAAAAABAAEAAAAzMIumIlK8oyhpHsnFZfhYumCYUhDAQxRIdhHBGqRoKw0R8DYlJd8z0fMDgsGo/IpHI5TAAAIfkECQoAAAAsAAAAABAAEAAAAzIIunInK0rnZBTwGPNMgQwmdsNgXGJUlIWEuR5oWUIpz8pAEAMe6TwfwyYsGo/IpFKSAAAh+QQJCgAAACwAAAAAEAAQAAADMwi6IMKQORfjdOe82p4wGccc4CEuQradylesojEMBgsUc2G7sDX3lQGBMLAJibufbSlKAAAh+QQJCgAAACwAAAAAEAAQAAADMgi63P7wCRHZnFVdmgHu2nFwlWCI3WGc3TSWhUFGxTAUkGCbtgENBMJAEJsxgMLWzpEAACH5BAkKAAAALAAAAAAQABAAAAMyCLrc/jDKSatlQtScKdceCAjDII7HcQ4EMTCpyrCuUBjCYRgHVtqlAiB1YhiCnlsRkAAAOwAAAAAAAAAAAA=="/>
    </div>
</form>

在我的本地应用程序中，它通过 URL 发布旧式表单变量，我无法让它在 LoginCtrl 内部触发 login.loginUser 函数.

In my local app, it is posting the old-style form variables via the URL, and I cannot get it to fire the login.loginUser function below inside LoginCtrl.

提前谢谢你...

推荐答案

由于某些奇怪的原因(可能是 ui-router 版本控制)，controllerAs 无法正常工作.

for some odd reason (perhaps ui-router versioning) the controllerAs is not working.

戴安娜的回答是有效的，但它不使用 controlleras 语法.如果您仍想使用它，请将 ui-router 设置更改为:

Diana´s answer is valid, but it doesn´t use the controlleras syntax. If you still want to use it, change the ui-router setting to:

.state('login', {
        url: "/login",
        templateUrl: "login-form.html",
        controller: 'LoginCtrl as login',
    })

这应该可以解决问题；)

That should do the trick ;)
