如何将下拉菜单与单选按钮同步，以便当我选中一个按钮时，下拉菜单会以相同的选项动态更改？

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.colors = [
        {model : "Red"},
        {model : "Green"},
        {model : "Blue"},
        {model : "Purple"}
    ];
});

<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>

<div ng-app="myApp" ng-controller="myCtrl">

<p>What is your favorite color?</p>

<select ng-model="selectedColor" ng-options="x.model for x in colors">
</select>
<input type="radio" ng-model="colors.model" value = "{{selectedColor.model}}"> Red
<input type="radio" ng-model="colors.model" value = "{{selectedColor.model}}"> Green
<input type="radio" ng-model="colors.model" value = "{{selectedColor.model}}"> Blue
<input type="radio" ng-model="colors.model" value = "{{selectedColor.model}}"> Purple

</div>

</body>

一种方法是使用相同的ng-model，这意味着您想要考虑无线电的相应值，以及数组中的对象

 var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.colors = [
        {model : "Red"},
        {model : "Green"},
        {model : "Blue"},
        {model : "Purple"}
    ];
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>

<div ng-app="myApp" ng-controller="myCtrl">

<p>What is your favorite color?</p>

<select ng-model="selectedColor" ng-options="x.model for x in colors">
</select>
<input name='rad' type="radio" ng-model="selectedColor" ng-value="colors[0]"> Red
<input name='rad' type="radio" ng-model="selectedColor"  ng-value="colors[1]" > Green
<input name='rad' type="radio" ng-model="selectedColor"  ng-value="colors[2]"> Blue
<input name='rad' type="radio" ng-model="selectedColor"  ng-value="colors[3]"> Purple

</div>

其他几种方法是在每个方法上使用ng-change并更新其他内部函数，或在不同ng-model上使用手表并在这些手表中更新其他
