I'm writing my first application in AngularJS, and I'm new to javascript. I have a simple question:
我正在AngularJS中编写我的第一个应用程序，而且我是javascript的新手。我有一个简单的问题：
How do I use POST values from an html form in an angular controller?
如何在角度控制器中使用html表单中的POST值？
I have a form (i've stripped out the css and validation stuff for ease of reading):
我有一个表单（为了便于阅读，我已经删除了css和验证内容）：
<form name="signupForm" novalidate>
<input type="text" placeholder="Name..." ng-model="name" name="name" required />
<input type="email" name="email" ng-model="email" placeholder="Email..." required>
<input type="password" placeholder="Password..." ng-model="password" name="password" required ng-minlength="7" ng-maxlength="50"/>
<button type="button" ng-click="auth.signup()">Sign Up</button>
</form>
I have a controller (no errors), with a function which looks a bit like this:
我有一个控制器（没有错误），其功能看起来有点像这样：
function SignupController($http, $scope, $rootScope, $location) {
vm.signup = function(name, email, password, onSuccess, onError) {
$http.post('http://myapi.com/api/authenticate/signup',
{
name: name,
email: email,
password: password
}).then(function(response) {
// etc
});
}
Now, how do I assign the values name, email, password from the form to name, email, password in the controller?
现在，如何将表单中的值名称，电子邮件，密码分配给控制器中的名称，电子邮件，密码？
Thanks.
谢谢。

When you set the input with ng-model="email", then you can access those variable values in controller by just calling $scope.email.
使用ng-model =“email”设置输入时，只需调用$ scope.email即可在控制器中访问这些变量值。
Case-1: For single value
案例1：单值
HTML
HTML
<input type="text" ng-model="email" />
Angular Controller
角度控制器
console.log($scope.email);
Case-2: For multiple values
案例2：对于多个值
HTML
HTML
<input type="text" ng-model="user.firstname" />
<input type="text" ng-model="user.lastname" />
<input type="text" ng-model="user.email" />
Angular Controller
角度控制器
//This will print the all the values (firstname, lastname, email) contains user as object.
console.log($scope.user);

<input type="text" placeholder="Name..." ng-model="user.name" name="name" required />
<input type="email" name="email" ng-model="user.email" placeholder="Email..." required>
<input type="password" placeholder="Password..." ng-model="user.password" name="password" required ng-minlength="7" ng-maxlength="50"/>
<button type="submit">Sign Up</button>
</form>
</body>#2

You need to use $scope for binding ng-model's value as shown as follow...
您需要使用$ scope来绑定ng-model的值，如下所示...
$scope.signup = function() {
data={
name: $scope.name,
email: $scope.email,
password: $scope.password
}
$http.post('http://myapi.com/api/authenticate/signup',data).then(function(response) {
// etc
});
