ngSubmit 不是控制器中的触发功能

Question

我对AngularJS和javascript比较陌生，请在回答时手下留情。

我正在尝试创建一个我想嵌套控制器的示例应用程序。 MainController 将始终作为父容器，如果用户登录，它将在顶部呈现菜单和用户名。现在我正在检查用户是否存储在 localStorage 中。

每个页面都有自己的控制器，可以执行页面特定的操作。

我卡在 ng-submit 上了，为什么它不起作用？

感谢任何帮助。

Answer 1

编辑您的代码：

<input type="submit" value="submit" id="submit" ng-submit="login()"></input>

必须如下：

<input type="submit" value="submit" id="submit" ng-click="submit()"></input>

Answer 2

我认为你的 login.html 有问题。删除 login() 因为你有 submit()

<from ng-submit="submit()">
    <input type="text" id="username" ng-model="username"></input>
    <input type="password" id="password" ng-model="password"></input>
    <input type="submit" value="submit" id="submit"></input>
</form>

Answer 3

请更改您的代码。看来你拼错了。

<from ng-submit="submit()">

至：

<form ng-submit="submit()">

同样替换下面的代码。

<input type="submit" value="submit" id="submit" ng-click="submit()"></input>

Answer 4

这里不需要ng-submit="login()"type="submit就够了最后一个是button不是input

<from ng-submit="submit()">
    <input type="text" id="username" ng-model="username"></input>
    <input type="password" id="password" ng-model="password"></input>
    <button type="submit" value="submit" id="submit"></button>
</form>

ngSubmit 不是控制器中的触发功能

ngSubmit is not triggering function in controller

javascript

html

angularjs

ng-submit
