Question

我有两个列表，我连接它们没有重复值，我这样做，所以我有重复值，为什么..？

在我的HTML中

..
          <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中

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;
    };

    }]);

尝试使用原生角度工具：angular.extend（dst，src）; 在你的情况下，它将是angular.extend（平台，平台可行）

它不会尝试深度比较对象，只会尝试它们的键值对，因此它可以帮助您获得独特平台的连续列表。

Concat列表没有重复
