我正在使用AngularUI-Bootstrap实现typeahead.我需要根据来自数据库的一些值显示分组结果.这是一个示例场景

根据此处提供的Typeahead文档,我认为没有任何选项可以满足我的要求.
我尝试过这种解决方法:每当typeahead数组形成时,我都会将用户部门附加到数组元素:
$scope.fetchUsers = function(val) {
console.log("Entered fetchUsers function");
return $http.get("http://localhost:8080/TestWeb/users", {
params : {
username : val
}
}).then(function(res) {
console.log("Response:",res);
var users = [];
angular.forEach(res.data, function(item) {
users.push(item.UserName + " - " + item.UserDepartment);
});
console.log("users=",users);
return users;
});
};

这样,至少最终用户可以看到该部门.但是当我选择记录时,所选值是数组元素的全部内容.以下是详细说明的示例截图:
HTML
用户来自本地服务<pre>Model: {{userList | json}}</pre>
<input type="text" ng-model="userList" placeholder="Users loaded from local database"
typeahead="username for username in fetchUsers($viewValue)"

我需要将多个目录从一个位置复制到另一个位置.因此,将会有多个xcopy声明,一个接一个.
每个文件夹中的文件数量都很大.有没有办法可以xcopy并行运行这些语句?我能想到的一个选项是 - xcopy在一个单独的批处理文件中调用每个选项,并使用@start而不是调用这些批处理文件@call.
还有其他选择吗?
