联合清单没有重复

Question

我有两个列表，我concat他们没有重复的vlaue，我这样做，所以我有重复价值，为什么......？

在我的HTML：

.. 
      <list-of-items items="platforms.concat(platformsCible).unique()" 
          label="$item" 
          selected-item="platform" 
          createfunction="add_platform($name)" 
          selectable="true" 
          editable="false" 
          size="small"> 
      </list-of-items> 
.. 

在我的JS

propertiesModule.controller('PropertiesCtrl', ['$scope', '$routeParams', 'PropertiesService', 'ApplicationService', 'PlatformService', 'Page', function ($scope, $routeParams, PropertiesService, ApplicationService, PlatformService, Page) { 
... 
    $scope.platforms = []; 

    /* Find all the platforms */ 
    PlatformService.get($routeParams.application, $routeParams.version).then(function(platforms){ 
     $scope.platforms = platforms; 
    }).then(function(){ 
     /* If platform was mentionned in the route, try to find it or add it */ 
     if($scope.platform) $scope.add_platform($scope.platform); 
    }); 

/* Find all the platforms cible */ 
if($routeParams.versionCible != null) { 
    PlatformService.get($routeParams.application, $routeParams.versionCible).then(function (platforms) { 
     $scope.platformsCible = platforms; 
    }).then(function() { 
     /* If platform was mentionned in the route, try to find it or add it */ 
     if ($scope.platformCible) $scope.add_platform($scope.platformCible); 
    }); 
} 

    Array.prototype.unique = function() { 
     var a = this.concat(); 
     for(var i=0; i<a.length; ++i) { 
      for(var j=i+1; j<a.length; ++j) { 
       if(a[i] === a[j]) 
        a.splice(j--, 1); 
      } 
     } 

     return a; 
    }; 

    }]);

尽量使用原生角工具：angular.extend（DST ，src）; 在你的情况下，它将是angular.extend（平台，平台）

它不会尝试深入比较对象，只有它们的键值对，所以它可能会为你工作得到独特的平台列表。
