angular实现两个select选择框互相传值

angular实现两个select选择框互相传值

思路就是两个select下拉框作为展示,实际操作两个数组之间内容的增加和删除,

实现代码如下:

$scope.fileTypeOption = [{
            type: 'SourceCode',
            name: '源码'
        }, {
            type: 'DesignPicture',
            name: '设计图'
        }, {
            type: 'Document',
            name: '文档'
        }, {
            type: 'Video',
            name: '视频'
        }];
        $scope.typeSelect = null;

        // $scope.

        $scope.ListCount = [""];
        $scope.showtoHtml = [];
        $scope.toIndex = [];
        $scope.typetoSelect = null;
        $scope.from = function() {
            if ($scope.typeSelect != null) {
                var showtoList;
                // console.log(type);
                for (var i = 0; i < $scope.typeSelect.length; i++) {
                    switch ($scope.typeSelect[i]) {
                        case "SourceCode":
                            showtoList = {
                                type: 'SourceCode',
                                name: '源码'
                            };
                            break;
                        case "DesignPicture":
                            showtoList = {
                                type: 'DesignPicture',
                                name: '设计图'
                            }
                            break;
                        case "Document":
                            showtoList = {
                                type: 'Document',
                                name: '文档'
                            }
                            break;
                        case "Video":
                            showtoList = {
                                type: 'Video',
                                name: '视频'
                            }
                            break;
                        default:
                            break;

                    }
                    for (var j = 0; j < $scope.fileTypeOption.length; j++) {
                        if ($scope.fileTypeOption[j].type == $scope.typeSelect[i]) {
                            $scope.fileTypeOption.splice(j, 1);
                        }
                    };
                    $scope.showtoHtml.push(showtoList);
                    // console.log($scope.showtoHtml);
                }
            } else {
                Notifier.notifyWarning("至少选中一项");
            }
            $scope.typeSelect=null;
        };

        $scope.to = function() {
            if ($scope.typetoSelect != null) {
                for (var i = 0; i < $scope.typetoSelect.length; i++) {
                    var showBack;
                    switch ($scope.typetoSelect[i]) {
                        case "SourceCode":
                            showBack = {
                                type: 'SourceCode',
                                name: '源码'
                            };
                            break;
                        case "DesignPicture":
                            showBack = {
                                type: 'DesignPicture',
                                name: '设计图'
                            }
                            break;
                        case "Document":

                        case "Video":
                            showBack = {
                                type: 'Video',
                                name: '视频'
                            }
                            break;
                        default:
                            break;
