[英]Angularjs: How do I get the item in a list when using ngChange?
I'm trying to get the item that just changed in this small example, is there some kind of context I should use? 我试图在这个小例子中得到刚改变的项目,是否有某种上下文我应该使用? I hoped it would be as simple as just referring to $this, but that doesn't seem to work.
我希望它只是简单地引用$ this,但这似乎不起作用。
<html ng-app>
<head>
<script src="https://code.angularjs.org/1.2.9/angular.min.js"></script>
<script>
function myController($scope) {
$scope.items = [
{ id: 1, name: "First" },
{ id: 2, name: "Second" },
{ id: 3, name: "Third" }
];
$scope.test = function() {
// How do I get the object in the list related to the change i did?
// I.e. "{ id: 2, name: "Second" }" for the second item.
};
}
</script>
</head>
<body>
<div ng-controller="myController">
<table>
<tbody ng-repeat="item in items">
<tr>
<td>{{ item.id }}</td>
<td><input type="text" ng-model="item.name" ng-change="test()"/></td>
</tr>
</tbody>
</table>
</div>
</body>
