angularjs - md-chips 不适用于 md-autocomplete

我正在尝试处理这个片段，其中自动完成嵌入在芯片中。但是从自动完成中选择的项目不会转换为芯片。

来自自动完成的数据采用以下方式:{name:"John Doe", id:"1"}
请指教我哪里错了。

问候

这是我的芯片代码:

<md-chips ng-model="student_ex"
    md-autocomplete-snap
    md-transform-chip="transformChip($chip)"
    md-require-match flex>
       <md-autocomplete flex
            md-selected-item="student"
            md-search-text="searchText"
            md-items="item in searchStudent(searchText)"
            md-item-text="item.name"
            placeholder="Search for a Student to Exclude">
                <span md-highlight-text="searchText">ID: {{ item.id }} | Name: {{ item.name }}</span>
       </md-autocomplete>
       <md-chip-template>
                <span>
                    <strong>{{$chip}}</strong><em></em>
                </span>
       </md-chip-template>
</md-chips>

这是我的 searchStudent 和 transformChip:

$scope.searchStudent = function (query) {
    if ((/^\d+$/.test(query))) {
        var results = query ? $scope.student_list.filter(
            function (name) {
                var regex = new RegExp(query,'gi');
                return name.id.match(regex);
            }
        ) : $scope.student_list;
    } else {
        var results = query ? $scope.student_list.filter(
            function (name) {
                var lowercaseQuery = angular.lowercase(query);
                var regex = new RegExp(lowercaseQuery,'gi');
                return name.name.match(regex);
            }
        ) : $scope.student_list;
    }
    return results;
};

$scope.transformChip = function (chip) {
    return {items:chip};
}

最佳答案

初始化模型，如下所示:

$scope.student_ex = [];

angular.module('MyApp', ['ngMaterial']).controller('AppCtrl', function($scope) {
    $scope.student_list = $scope.student_list = [{name:"John Doe", id:"1"}, {name:"Antipod", id:"2"}];
    $scope.student_ex = [];

    $scope.searchStudent = function (query) {
        if ((/^\d+$/.test(query))) {
            var results = query ? $scope.student_list.filter(
                function (name) {
                    var regex = new RegExp(query,'gi');
                    return name.id.match(regex);
                }
            ) : $scope.student_list;
        } else {
            var results = query ? $scope.student_list.filter(
                function (name) {
                    var lowercaseQuery = angular.lowercase(query);
                    var regex = new RegExp(lowercaseQuery,'gi');
                    return name.name.match(regex);
                }
            ) : $scope.student_list;
        }
        return results;
    };

    $scope.transformChip = function (chip) {
        return chip;
    }
});
