通过HTML中的选择值更改AngularJS常量

<select ng-model="selectedValue">
    <option value="value1">选项1</option>
    <option value="value2">选项2</option>
    <option value="value3">选项3</option>
</select>

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.selectedValue = "value1"; // 默认选择值
    $scope.constantValue = "常量值1"; // 定义的常量
});

<div ng-controller="myCtrl">
    <p>选择的值：{{selectedValue}}</p>
    <p>常量的值：{{constantValue}}</p>
</div>
