Question

<accordion class="nested-accordion">
    <accordion-group ng-repeat="item in menu" is-open="item.opened" ng-if="item.children == true && item.grandchild == true">
          <accordion-heading id="inner-accordion">

         ---- PROBLEM HERE ----
            <div ng-click="item.opened = !item.opened" class="toggle-caret">
                  <span class="glyphicon glyphicon-play" ng-class="{true: 'caret-open', false:'caret-closed'}[item.opened]"></span>
              </div>


              <button class="btn-link filter-option" ng-class="{true:'option-checked', false:''}[item.checked]" ng-click="test(item, $event); $event.stopPropagation()">{{item.name}}</button>
          </accordion-heading>
                    <div>
                 <!--  some stuff here -->
                    </div>
                  </accordion-group>
                </accordion>

我在上面的代码中单独列出的一行有问题。 ng-click不会将 item.opened 从 true 切换为 false 。但是，如果我更改语法：

ng-click="item.opened = !item.opened"

为：

ng-click="item.opened != item.opened"

手风琴按预期工作。这不是我想要的。此外，这是手风琴中遇到此问题的唯一部分。谁能解释为什么这给我带来了困难？

使用＆＃34; var =！var＆＃34;
