创建一个指令以使 ng-keyup 成为备用搜索初始值设定项

我是 angular 的新手，我有几个文本字段、一个复选框和一个下拉菜单，我怎样才能按下 Enter 按钮，它会提交？ 我一直在阅读并找到了 ng-submit 函数，我将其放在我的表单中，但没有任何反应 我假设我将不得不在我的 angular 控制器中的某个地方激活它。

 <form ng-submit="search()">
            <div class="form-group">
                <label>Job Number</label>
                <input class="form-control" style="width: 92%" type="text" ng-model="jobNumber"/>
            </div>
        </form>
        <form ng-submit="search()">
            <div class="form-group">
                <label>Description</label>
                <input class="form-control" style="width: 92%" type="text" ng-model="description" />
            </div>
        </form>
    </div>
</div>

我没有在下面的控制器中做任何事情。

var CapitalRequestMultiMillInquiryController = function ($scope, $sce, $rootScope, $modal, $window, CapitalRequestService, PlantService) {

$rootScope.title = 'Capital Request Multi Mill Inquiry';
$scope.allMills = [];
$scope.mill = '';
$scope.jobNumber = '';
$scope.description = '';
$scope.amount = '';
$scope.amountOperator = '';
$scope.openOnly = '';
$scope.projectManager = '';
//$scope.allUsers = [];
//UsersService.getUsersWithId().then(function(objectTypes) {
//    $scope.allUsers = objectTypes
//});
//CapitalRequestService.searchMulti("http://tomcmmsweb.pca.com/CapitalRequest/Search", authenticatedUser.userName.toUpperCase(), $scope.selectedMill, $scope.jobNumber, $scope.description, $scope.amount, $scope.amountOperator, $scope.openOnly, $scope.projectManager).then(function (results) {
//    $scope.tomahawk = results;
//    for (var i = 0; i < $scope.tomahawk.length; i++)
//        $scope.tomahawk[i] = $sce.trustAsHTML($scope.tomahawk[i]);
//});

PlantService.getPlantId().then(function (mills) {
    $scope.allMills = mills
});
$scope.search = function() {
    //for each mill
    CapitalRequestService.searchMulti("http://coucmmsweb.pca.com/CapitalRequest/Search", authenticatedUser.userName.toUpperCase(), $scope.mill, $scope.jobNumber, $scope.description, $scope.amount, $scope.amountOperator, $scope.openOnly, $scope.projectManager).then(function (results) {

    });
