angularjs獲取到單選框的值的方法：
1、定義一組radio：
<label>Chicken or the Egg?</label>
<div class="form-group">
<div class="radio">
<label>
<input type="radio" name="chickenEgg" value="chicken" ng-model="formData.chickenEgg">
Chicken
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="chickenEgg" value="egg" ng-model="formData.chickenEgg">
Egg
</label>
</div>
</div>

2、js代碼如下：
var myApp = <b style="color:#000;background:#ffff66">angular</b>.module("myApp", []);
myApp.controller("myController", function($scope) {
$scope.selectedGender = '';
$scope.getRadioButtonValue = function(gender) {
// copy data
alert(gender);
$scope.selectedGender = <b style="color:#000;background:#ffff66">angular</b>.copy(gender);
};
});
