我正在用 AngularJS 编写我的第一个应用程序，而且我对 javascript 很陌生。我有一个简单的问题:
如何在 Angular Controller 中使用 html 表单中的 POST 值？
我有一个表单(为了便于阅读，我删除了 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>
我有一个 Controller (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
});
}
现在，如何将表单中的名称、电子邮件、密码值分配给 Controller 中的名称、电子邮件、密码？
谢谢。
最佳答案
当您使用 ng-model="email"设置输入时，您只需调用 $scope.email 即可访问 Controller 中的这些变量值。
Case-1: For single value
HTML
<input type="text" ng-model="email" />
Angular Controller
console.log($scope.email);
Case-2: For multiple values
HTML
<input type="text" ng-model="user.firstname" />
<input type="text" ng-model="user.lastname" />
<input type="text" ng-model="user.email" />
Angular Controller
//This will print the all the values (firstname, lastname, email) contains user as object.
console.log($scope.user);
请检查此工作片段以查看实时示例
var app = angular.module('myApp', []);
app.controller('FormCtrl', function ($scope, $http) {
$scope.user = {};
$scope.signup = function(){
console.log($scope.user);
}
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp">
<form name="signupForm" ng-controller="FormCtrl" ng-submit="signup()">
<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>
