打开/选择时更改离子模态模板

Question

我有一个打开模态窗口的控制器。 如何在打开模态窗口时更改templateUrl值？

$ionicModal.fromTemplateUrl('modal-details.html', {
   scope: $scope,
    animation: 'slide-in-up',
    hardwareBackButtonClose: true
}).then(function (modal) {
    $scope.modal = modal;
});

//在这里打开窗口..

$scope.openModal = function(selected){

   // How can I change the templateUrl based on the selected value?


    $scope.data.selected = selected;
