有人可以告诉我该怎么做,这样当我按下"提交"按钮myName变量是否更新?谢谢!
app.js:
app.controller('SomeController', ['$scope', 'emails', function($scope, emails) {
emails.success(function(data) {
$scope.emails = data;
});
$scope.myName = "John";
}]);
view.html
<div ng-controller="SomeController">
<form name="messageForm" ng-submit="update(myName)">
<input type="text" ng-model="myName"/>
<h1>{{myName}}</h1>
<input type="submit" value="Send Message"/>
</form>
</div>

只要您键入:
,这将更新<input type="text" ng-model="myName"/>
<h1>{{myName}}</h1>
只有在您点击提交时才会更新:
<form name="messageForm" ng-submit="update(myName)">
<input type="text" ng-model="myName"/>
<h1>{{myUpdatedName}}</h1>
<input type="submit" value="Send Message"/>
</form>
您应该在控制器上:
$scope.update = function(name) {
$scope.myUpdatedName = name;
};
请记住,您的表单应该包含在宣布您的SomeController
的任何组件中...例如
<div ng-controller="SomeController">
<!-- your form goes here -->
</div>

看起来您错过了控制器中的更新功能:
app.controller('SomeController', ['$scope', 'emails', function($scope, emails) {
emails.success(function(data) {
$scope.emails = data;
});
$scope.myName = "John";
$scope.update = function(name) {
$scope.myName = name;
};
}]);
