ng-selected inside of ng-repeat 不起作用 (AngularJS)

Question

我正在尝试将值与我的 <select> 标签内的 "check" 和 <option> 标签进行比较，但找不到解决方案...

*这是一个管理页面，所以我已经有了 {{x.nivel}} 值。我只需要根据 ng-repeat.

中的每个 "inscritos" 将其标记为 "selected"

求助：\

            <li ng-repeat="x in inscritos | orderBy:'nome'">
                <select>
                    <option ng-selected="(this.value)=={{x.nivel}}" value="Iniciante">Iniciante</option>
                    <option ng-selected="(this.value)=={{x.nivel}}" value="Intermediário">Intermediário</option>
                    <option ng-selected="(this.value)=={{x.nivel}}" value="Avançado">Avançado</option>
                </select>
        </li>

Answer 1

不要在js表达式中使用{{}}：

 <li ng-repeat="x in inscritos | orderBy:'nome'">
    <select>
       <option ng-selected="x.nivel=='Iniciante'" value="Iniciante">Iniciante</option>
       <option ng-selected="x.nivel=='Intermediário'" value="Intermediário">Intermediário</option>
       <option ng-selected="x.nivel=='Avançado'" value="Avançado">Avançado</option>
     </select>
 </li>

双花括号符号 {{ }} 用于将值与 html 元素绑定。请参阅 templates 文档。
