Angular.js实现多个checkbox只能选择一个的方法示例

<div class="form-group">   <label class="col-sm-2 control-label">请选择文章主题色彩</label>   <div class="col-sm-10" theme-group>   <label class="i-switch m-t-xs m-r">    <input type="checkbox" input-theme >    <i></i>   </label>   <label class="i-switch bg-info m-t-xs m-r">    <input type="checkbox" input-theme>    <i></i>   </label>   <label class="i-switch bg-primary m-t-xs m-r">    <input type="checkbox" input-theme >    <i></i>   </label>   <label class="i-switch bg-danger m-t-xs m-r">    <input type="checkbox" input-theme>    <i></i>   </label>   </div></div>
