按Enter键时AngularJS表单不提交

Question

我正在尝试在用户按Enter键时提交登录表单.单击"登录"按钮时,表单完全正常,但按Enter键不起作用,此外,会导致奇怪的行为:

• 关联的函数ng-submit未被执行
• 按Enter键后,永远不再显示错误消息(登录失败)

这是我的标记:

<form ng-submit="login()" class="login-form">
    <div class="alert alert-danger" ng-class="{ 'display-hide': !showError }">
        <button class="close" data-close="alert"></button>
            <span> Login failed </span>
    </div>
    <div class="form-group">
        <label class="control-label visible-ie8 visible-ie9">Username</label>
        <input class="form-control form-control-solid placeholder-no-fix" type="text" autocomplete="off" placeholder="Username" name="username" ng-model="username"/>
    </div>
    <div class="form-group">
        <label class="control-label visible-ie8 visible-ie9">Password</label>
        <input class="form-control form-control-solid placeholder-no-fix" type="password" autocomplete="off" placeholder="Password" name="password" ng-model="password"/>
    </div>
    <div class="form-actions">
        <button class="btn btn-success uppercase">Login</button>
    </div>
</form>

请注意,我试图取代<button...>与<input type="submit"...>没有成功要么.

具有login() - 函数的相应控制器如下所示:

.controller('LoginCtrl', ['$rootScope', '$scope', ..., function LoginController ($rootScope, $scope, ...) {
    $scope.showError = false;

    $scope.login = function()
    {
        console.log("logging in");
        $http({
            url: $scope.apiEndpointLogin,
            method: 'POST',
            data: {'username': this.username, 'password': this.password}
        }).then(function(response) {
            $scope.showError = false;

            [...]
        }, function() {
            $scope.showError = true;
        });

    };
}]);

我运行angular v1.4.0并使用angular-ui-router v.0.2.15进行路由.

感谢您的任何意见,非常感谢.

把这一个

 <input type="submit" class="btn btn-success uppercase" value="Login" > 

代替

 <button class="btn btn-success uppercase">Login</button>

对于表单提交按钮应该是提交类型.

编辑代码:

<form   class="login-form"  ng-submit="login()" >
    <div class="alert alert-danger" ng-class="{ 'display-hide': !showError }">
        <button class="close" data-close="alert"></button>
            <span> Login failed </span>
    </div>
    <div class="form-group">
        <label class="control-label visible-ie8 visible-ie9">Username</label>
        <input class="form-control form-control-solid placeholder-no-fix" type="text" autocomplete="off" placeholder="Username" name="username" ng-model="username"/>
    </div>
    <div class="form-group">
        <label class="control-label visible-ie8 visible-ie9">Password</label>
        <input class="form-control form-control-solid placeholder-no-fix" type="password" autocomplete="off" placeholder="Password" name="password" ng-model="password"/>
    </div>
    <div class="form-actions">
        <input  type="submit" class="btn btn-success uppercase"  >
    </div>

</form>

另外,请检查您的LoginCtrl是否位于表单DOM之上.
