动态内容隐藏在Angular引导手风琴中

Dynamic content hidden in Angular Bootstrap accordion

本文关键字：手风琴 Angular 隐藏 动态      更新时间：2023-09-26

我有一个显示动态内容的手风琴。我的应用没有包含ngAnimate，因为客户端不需要动画。然而，我看到一个问题，动态内容隐藏时，不包括ngAnimate。当它被添加回来时，内容呈现得很好。这个场景是展开一个accordion元素。从那里，您可以执行一个动作，该动作将在手风琴主体内的动作下面呈现动态内容。内容将被切断一旦它超过手风琴主体的高度。折叠和展开accordion元素将强制重新计算body，并正确显示所有内容。我创造了一个普朗克来证明这个问题。

Java脚本代码:

    angular.module('ui.bootstrap.demo', ['ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('AccordionDemoCtrl', function ($scope) {
  $scope.oneAtATime = true;
  $scope.blah = ['blah'];
  $scope.view = false;

  $scope.status = {
    isFirstOpen: true,
    isFirstDisabled: false
  };
});
angular.module('ui.bootstrap.demo').directive('mydir',['$compile',function($compile){
  return{
    link:function(scope, element, attrs){
      scope.changeMe = function(){
    scope.blah.push('Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed tortor mi, molestie sit amet malesuada quis, mollis in mi.

Proin ultrices, purus sit amet finibus ornare, nisl justo faucibus arcu, et cursus ante arcu sit amet augue.;');
  };
      var template = '<button type="button" class="btn btn-default btn-sm" ng-click="changeMe()">Add content below</button><div ng-repeat="stuff in blah track by $index"><div ng-if="stuff.length > 5">{{stuff}}</div></div>';
      element.empty();
      element.html(template);
      $compile(element.contents())(scope);
    },
    restrict:'E'
  }
}]);

      </div>
    </div>
  </script>
  <p>This demonstrates a hidden content issue when ng-animate is not present.</p>
  <p>Click "Add content below".  It will be mostly hidden.  Then collapse and expand Header 1.  The body will be recalculated and everything will be visible.</p>
  <uib-accordion close-others="false">
    <uib-accordion-group ng-init="status.open=true" is-open="status.open">
      <uib-accordion-heading>
        Header 1 - My dynamic content will disappear. <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': status.open, 'glyphicon-chevron-right': !status.open}"></i>
      </uib-accordion-heading>
      <div><mydir></mydir></div>
    </uib-accordion-group>
    <uib-accordion-group is-open="status.isFirstOpen">
      <uib-accordion-heading>
        Header 2 <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': status.isFirstOpen, 'glyphicon-chevron-right': !status.isFirstOpen}"></i>
      </uib-accordion-heading>
      This content is straight in the template.
    </uib-accordion-group>

  </uib-accordion>
</div>
  </body>
</html>

除非我误解了Angular-UI bootstrap文档，否则如果你想要动画，你只需要使用ngAnimate。

有人遇到过这个问题并找到了解决方案吗?当要禁用动画时，是否需要设置其他选项?我注意到，即使没有包含ngAnimate，转换仍然存在。

似乎在0.14.0之后的ui.bootstrap中有一些东西已经打破了这种行为，但我无法在源代码中找到它。

如果你用0.13.4版本尝试你的代码，它会像预期的那样工作。请查看更新后的plunkr。

Issue已经添加到github。
