angular-ui-bootstrap，去掉最后一个tab，整个页面都刷新了

Question

我添加了 ng-click 事件来删除 uib-tab-heading.Everything 中的选项卡是可以的，但是当我删除最后一个选项卡时，整个页面都刷新了，这不是预期的。这是我的代码：http://embed.plnkr.co/f0p9uZgKuWTNh3Ss7okY.

html

  <head>
    <link data-require="bootstrap-css@3.3.7" data-semver="3.3.7" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.css" />
    <script data-require="angularjs@1.6.2" data-semver="1.6.2" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.2/angular.js"></script>

    <script src="script.js"></script>
  </head>

  <body>
    <div ng-controller="TabsDemoCtrl">
      <uib-tabset active="active">
        <uib-tab index="0" heading="Static title">Static content</uib-tab>
        <uib-tab index="$index+1" ng-repeat="tab in tabs  track by $index">
          <uib-tab-heading>
                    {{tab.title}}
              <div class="close" aria-label="Close" ng-click="remove($index)">
              <span aria-hidden="true">×</span>
            </div>
            <!--<div style="width: 10px; height: 10px; background-color: red;" ng-click="removeTab($index)"></div>-->
          </uib-tab-heading>


                {{tab.content}}
            </uib-tab>
      </uib-tabset>
    </div>
  </body>

</html>

js

angular.module('app', ['ui.bootstrap']).controller('TabsDemoCtrl', function ($scope, $window) {
    $scope.tabs = [{
            title: 'Dynamic Title 1',
            content: 'Dynamic content 1'
        },
        {
            title: 'Dynamic Title 2',
            content: 'Dynamic content 2',
        },
        {
            title: 'Dynamic Title 3',
            content: 'Dynamic content 3',
        },
        {
            title: 'Dynamic Title 4',
            content: 'Dynamic content 4',
        }   
    ];

    $scope.remove = function (index) {
        $scope.tabs.splice(index, 1);
        $scope.active = $scope.tabs.length;
    };
});

感谢您的帮助。

Answer 1

<uib-tab-heading> 本身被 <a> 标签包裹，因此页面似乎是由于默认的 link 单击操作而刷新的。

做

<div ng-click="remove($index, $event)">

$scope.remove = function(index, event){
    event.preventDefault();
    ...
}

Answer 2

您需要使用 ng-click 提供的 $event 对象，如文档所述：https://docs.angularjs.org/api/ng/directive/ngClick

html:

ng-click="remove($index, $event)"

js

$scope.remove = function (index, e) {
    $scope.tabs.splice(index, 1);
    $scope.active = $scope.tabs.length;
    e.preventDefault();
};
