我有重复学生的Gender个电台选项。请参阅下面的代码。如何为每个学生选择默认广播为'Male'？

<ng-repeat student in Students>
<div class="form-group col-lg-12 col-sm-8">
    <label class="col-lg-2 control-label">Gender </label>
    <div class="button-holder col-lg-2">
        <input type="radio" class="regular-radio" id="radioY_{{$index + $parent.$index}}" data-ng-model="student.Gender" data-ng-value="true" />
        <label for="radioY_{{$index + $parent.$index}}">
            <span class="Radiobox-txt" id="radioY_{{$index}}">Male</span>
        </label>
    </div>
    <div class="button-holder col-lg-2">
        <input type="radio" class="regular-radio" id="radioN_{{$index + $parent.$index}}" data-ng-model="student.Gender"  data-ng-value="false" />
        <label for="radioN_{{$index + $parent.$index}}">
            <span class="Radiobox-txt" id="radioN_{{$index + $parent.$index}}">Female</span>
        </label>
    </div>
</div>
</div>

选择单选按钮后，

ng-value应包含要设置给模型的值。在您的情况下，将ng-value分配给男性＆＃39;并且在定义对象student时分配＆＃39;男性＆＃39;到student.Gender
