javascript - Angular.js : get different form {{display. value}} 和 $scope.value 来自相同的 ng-model

Question

示例表单:

<select ng-model="coffee.location">
    <option display-value='Some verbose message here' value="home">At home</option>
    <option display-value='Some verbose message here' value="work">At work</option>
    <option display-value='Some verbose message here' value="chain">Coffee Shop Chain (i.e. Starbucks &amp; Costa)</option>
    <option display-value='Some verbose message here' value="independent">Independent Coffee Shop</option>
</select>

显示元素示例:

<div>{{ coffee.location }}</div>

<小时/>

问题:如何让我的 Angular Controller 接收 option[value]，同时让 {{coffee.location}} 显示 option[display-value] >(或者它需要的任何属性)？

我希望我的问题很清楚。提前干杯。

什么有效(由@dfsq提供)

相关 JavaScript:

app.controller('SuggestionController', ['$scope', function($scope) {
    $scope.stringMap = {
        home:   'cosy up at home',
        work:   'lounge at work',
        chain:  'patrol the highstreet'
    };
}]);

相关 HTML:

<div id="some_parent" ng-app ng-controller="SuggestionController">
    ...
    <select ng-model="coffee.location">
        <option value="home">At home</option>
        <option value="work">At work</option>
        <option value="chain">Coffee Shop Chain</option>
        <option value="independent">Independent</option>
    </select>
    ...
</div>

{{stringMap[coffee.location]}}
