Question

我有下面的angularjs代码，通过按下新按钮创建标签。但是新创建的选项卡在创建后不会激活或选中。始终是最后一个活跃之前！谁知道什么是错的？

Javascript：

var app = angular.module('plunker', ['ngAnimate','ui.bootstrap']);

app.controller("TabsParentController", function ($scope,$uibModal) {
  $scope.animationsEnabled = true;

  $scope.open = function (size, workspace) {

    var modalInstance = $uibModal.open({
      animation: $scope.animationsEnabled,
      templateUrl: 'myModalContent.html',
      controller: 'ModalInstanceCtrl',
      size: size,
      resolve: {

         workspace: function () {
          return workspace;
        }

      }
    });

    modalInstance.result.then(function (selectedItem) {
       var index=$scope.workspaces.indexOf(selectedItem)
      $scope.workspaces.splice(index,1);     
    }, function () {
      $log.info('Modal dismissed at: ' + new Date());
    });
  };



    var setAllInactive = function() {
         //angular.forEach($scope.workspaces, function(workspace) {
           // workspace.active = false;
   // });
    };
    var addNewWorkspace = function() {

        var id = $scope.workspaces.length+1 ;

        $scope.workspaces.push({
            id: id,

            name: "Workspace " + id,

        });
        $scope.active=$scope.workspaces.length -1;


    };

    $scope.workspaces =
    [

    ];

    $scope.addWorkspace = function () {
        setAllInactive();
        addNewWorkspace();

    };    


     $scope.remove=function(item){ 
      var index=$scope.workspaces.indexOf(item)
      $scope.workspaces.splice(index,1);     
    }

});

angular.module('plunker').controller('ModalInstanceCtrl', function ($scope, $uibModalInstance, workspace) {

  $scope.selectedworkspace = workspace;

  $scope.ok = function () {
    $uibModalInstance.close( $scope.selectedworkspace );
  };

  $scope.cancel = function () {
    $uibModalInstance.dismiss('cancel');
  };
});




app.controller ("TabsChildController", function($scope, $log){

});

如果您希望将最新的标签设置为有效，则需要设置

$scope.active = $scope.workspaces.length;

但另一个问题是，当您推送新工作区时。指令重新渲染DOM并准备好所有范围变量需要一些时间。因此，在推送之后，如果您尝试将最新选项卡指定为活动将导致错误。

所以，为了快速证明我的观点（没有最正确的方法），试试这个，你的代码就可以了。记得将$ timeout作为依赖注入

app.controller("TabsParentController", 
    function ($scope,$uibModal, $timeout) {


        ....
        ....

        $scope.workspaces.push({
            id: id,
            name: "Workspace " + id,
        });

        //introduce a 50 ms delay before setting the active tab
        $timeout(function(){
           $scope.active = $scope.workspaces.length;
        }, 50);

        ....
        ....

    }
);
