Question

我正在使用ui-bootstrap angularjs生成向下滑动并添加了一个按钮和单击事件，控制器中有警报消息，但我没有收到任何警报或控制台日志。

我在使用template-url加载的按钮点击时生成警报时遇到问题，如下面的代码所示。我在下面分享我的示例代码。

＆＃13;

angular.module('ui.bootstrap.demo', [ 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('AccordionDemoCtrl', function ($scope) {
  console.log("CTRL LOADED");
  $scope.alertMsg = function(){
    alert('hejd');
  }
});

＆＃13;

          <a href tabindex="0" class="accordion-toggle" ng-click="toggleOpen()" uib-accordion-transclude="heading">

              {{heading}}

        </h4>
      </div>
      <div class="panel-collapse collapse" uib-collapse="!isOpen">
        <div class="panel-body" style="text-align: right" ng-transclude></div>

        Custom template with custom header template <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': status.isCustomHeaderOpen, 'glyphicon-chevron-right': !status.isCustomHeaderOpen}"></i>
      </uib-accordion-heading>
      World
    </div>
    
  </uib-accordion>
</div>
  </body>
</html>

我确实得到了日志＆＃34; CTRL LOADED＆＃34;。但是当我点击时，我没有得到警告信息。

我相信该面板会创建自己的范围，因此您需要调用父范围来获取警告消息，如下所示：

    <div ng-controller="AccordionDemoCtrl">
  <script type="text/ng-template" id="group-template.html">
    <div class="panel panel-default">
      <div class="panel-heading">
        <h4 class="panel-title" style="color:#fa39c3">
        <button ng-click="$parent.alertMsg()">Btn</button>
          <a href tabindex="0" class="accordion-toggle" ng-click="toggleOpen()" uib-accordion-transclude="heading">
            <span uib-accordion-header ng-class="{'text-muted': isDisabled}">
              {{heading}}
            </span>
          </a>
        </h4>
      </div>
      <div class="panel-collapse collapse" uib-collapse="!isOpen">
        <div class="panel-body" style="text-align: right" ng-transclude></div>
      </div>
    </div>
  </script>

语法controllerAs并不漂亮，实际上你需要使用它。

<button ng-click="orderCtrl.alertMsg()">Btn</button>

将click事件动态绑定到template-url源中的按钮
