我想用一些动态问题填充表单(fiddle
here)：
<div ng-app ng-controller="QuestionController">
<ul ng-repeat="question in Questions">
<li>
<div>{{question.Text}}</div>
<select ng-model="Answers['{{question.Name}}']" ng-options="option for option in question.Options">
</select>
</li>
</ul>
<a ng-click="ShowAnswers()">Submit</a>
</div>
function QuestionController($scope) {
$scope.Answers = {};
$scope.Questions = [
{
"Text": "Gender?","Name": "GenderQuestion","Options": ["Male","Female"]},{
"Text": "Favorite color?","Name": "ColorQuestion","Options": ["Red","Blue","Green"]}
];
$scope.ShowAnswers = function()
{
alert($scope.Answers["GenderQuestion"]);
alert($scope.Answers["{{question.Name}}"]);
};
}
一切正常，除了模型是字面上的答案[“{{question.Name}}”]，而不是评估的Answers [“GenderQuestion”]。如何动态设置模型名称？

你可以简单地将JavaScript表达式放在ng-model中。
