我想捕捉下面文本框上的回车键事件。为了更清楚地说明这一点，我使用ng-repeat填充tbody。下面是HTML:
<td><input type="number" id="closeqty{{$index}}" class="pagination-right closefield"
data-ng-model="closeqtymodel" data-ng-change="change($index)" required placeholder="{{item.closeMeasure}}" /></td>
这是我的模块:
angular.module('components', ['ngResource']);
我使用一个资源来填充表，我的控制器代码是:
function Ajaxy($scope, $resource) {
//controller which has resource to populate the table
}

另一种方法是使用标准指令ng-keypress="myFunct($event)"
然后在你的控制器中你可以有:
...
$scope.myFunct = function(keyEvent) {
if (keyEvent.which === 13)
alert('I am an alert');
}
...

你需要添加一个指令，像这样:
Javascript:
app.directive('myEnter', function () {
return function (scope, element, attrs) {
element.bind("keydown keypress", function (event) {
if(event.which === 13) {
scope.$apply(function (){
scope.$eval(attrs.myEnter);
});
event.preventDefault();
}
});
};
});
HTML:
<div ng-app="" ng-controller="MainCtrl">
<input type="text" my-enter="doSomething()">
</div>
另一种方法是使用标准指令ng-keypress="myFunct($event)"
然后在你的控制器中你可以有:
...
$scope.myFunct = function(keyEvent) {
if (keyEvent.which === 13)
alert('I am an alert');
}
...
你可以使用ng-keydown ="myFunction($event)"作为属性。
<input ng-keydown="myFunction($event)" type="number">
myFunction(event) {
if(event.keyCode == 13) { // '13' is the key code for enter
// do what you want to do when 'enter' is pressed :)
}
}

}

这个呢?：
<form ng-submit="chat.sendMessage()">
<input type="text" />
<button type="submit">
</form>
现在，当你在输入后按回车键时，表单知道如何处理它。
