问题描述
我新的角度，我试图获得该用户已采用NG-模式选择的单选按钮的值。但我没有得到在选定的联系人任何输出。
I am new to Angular and I am trying to obtain the value of the radio button that the user has selected using ng-model. But I am not getting any output in "selected contact".
下面是我的HTML
<!doctype html>
<html ng-app>
<head>
<script src="http://code.angularjs.org/1.2.0rc1/angular.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<form name="myForm" ng-controller="Ctrl">
<table border="0">
<th>Contact Type</th>
<tr ng-repeat="contact in contacttype"><td>
<input type="radio" ng-model="contactname" name="group1" value="{{contact.name}}">{{contact.name}}
</td>
</td></tr></table>
<tt>selected contact = {{contactname}}</tt><br/>
</form>
</body>
</html>
下面是我的main.js
Below is my main.js
function Ctrl($scope) {
$scope.contacttype = [
{name: 'Both' },
{name: 'User'},
{name: 'Admin'}
];
}
我在做什么错在这里？没能弄清楚！
What am I doing wrong here? Not able to figure out !!!
推荐答案
由于 NG-重复创建其自己的范围，你正在尝试做的是将值赋给从子范围父范围。所以，你可以做
Because ng-repeat creates its own scope and what you are trying to do is assign the value to the parent scope from the child scope. So you can do
<input type="radio" ng-model="$parent.contactname" name="group1" value="{{contact.name}}">
