可能是愚蠢的问题，但我有我的html表单简单的输入和按钮:
<input type="text" ng-model="searchText" />
<button ng-click="check()">Check!</button>
{{ searchText }}
然后在控制器中(模板和控制器由routeProvider调用):
$scope.check = function () {
console.log($scope.searchText);
}
为什么我看到视图更新正确，但在控制台未定义时，单击按钮?
谢谢!
更新: 似乎我已经解决了这个问题(之前不得不提出一些变通办法): 只需要把我的属性名从searchText改为search。文本，然后定义空$scope。搜索= {};对象，瞧……但我不知道为什么它能起作用;]

你可以这样做，在ng键下搜索输入文本，在ng键下点击图标:
<input type="text" ng-model="searchText" ng-keypress="keyEnter(this,$event)" />
<button ng-click="check(searchText)">Check!</button>
in the controller
$scope.search = function (searchText) {
console.log(searchText);
}
$scope.keyEnter = function (serachText,$event) {
var keyCode = $event.which || $event.keyCode;
if (keyCode === 13) {//KeyCode for Enter key
console.log(searchText);
}
}

我也面临着同样的问题…… 对我来说有效的解决方法是使用这个关键字..........
警报(this.ModelName);
我只是在使用绑定到body元素的root_controller时遇到了这个问题。然后我在angular路由器中使用ng-view。问题是，当angular将html插入ng-view元素时，总是会创建一个新的作用域。因此，我的“check”函数是在ng-model元素修改的作用域的父作用域中定义的。
要解决这个问题，只需在路由加载的html内容中使用专用控制器。
为表单控件提供name属性
I came across the same issue when dealing with a non-trivial view (there are nested scopes). And finally discovered this is a known tricky thing when developing AngularJS application due to the nature of prototype-based inheritance of java-script. AngularJS nested scopes are created through this mechanism. And value created from ng-model is placed in children scope, not saying parent scope (maybe the one injected into controller) won't see the value, the value will also shadow any property with same name defined in parent scope if not use dot to enforce a prototype reference access. For more details, checkout the online video specific to illustrate this issue, http://egghead.io/video/angularjs-the-dot/ and comments following up it.
