需求：实现点击子选项，父选项自动勾选，当子选项没有勾选，对应的父选项不勾选，并把勾选的对应的id发送出去。
效果图：
<!DOCTYPE html> <html data-ng-app="App"> <head> <script src='angular-1.3.0.js'></script> <script src="script2.js"></script> </head> <body data-ng-controller="AddStyleCtrl"> <div>Choose Tags</div> <div> <div>You have choosen:</div> <hr> {{selected}} <table class="table table-bordered table-striped table-center" style="margin-top: 20px;"> <tbody> <tr data-ng-repeat="category in tagcategories"> <th class="inner" style="vertical-align: middle !important;">{{category.name }} <input type="checkbox" id={{category.id}} name="{{category.name}}" ng-checked="isSelected(category.id)" ng-click="updateSelection($event,category.id)"> </th> <td> <span data-ng-repeat="tag in category.tags"> <input type="checkbox" id={{tag.id}} name="{{tag.name}}" ng-checked="isSelected(tag.id)" ng-click="updateSelection($event,tag.id,category.id)"> {{ tag.name }} </span> </td> </tr> </tbody> </table> </div> <pre>{{selected|json}}</pre> </body> </html>
