尝试使用angular.module('ui.bootstrap.demo', ['ngAnimate', 'ngSanitize', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('ModalDemoCtrl', function ($uibModal, $log, $document) {
var $ctrl = this;
$ctrl.animationsEnabled = true;
$ctrl.name = "Manikandan";
$ctrl.open = function (size, parentSelector) {
var parentElem = parentSelector ?
angular.element($document[0].querySelector('.modal-demo ' + parentSelector)) : undefined;
var modalInstance = $uibModal.open({
animation: $ctrl.animationsEnabled,
ariaLabelledBy: 'modal-title',
ariaDescribedBy: 'modal-body',
templateUrl: 'myModalContent.html',
controller: 'ModalInstanceCtrl',
controllerAs: '$ctrl',
size: size,
appendTo: parentElem,
resolve: {
values: function () {
return $ctrl.name;
}
}
});
modalInstance.result.then(function () {
$ctrl.msg = "Submitted";
$ctrl.suc = true;
}, function(error) {
$ctrl.msg = 'Cancelled';
$ctrl.suc = false;
});
};
});
angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl', function ($uibModalInstance, values) {
var $ctrl = this;
$ctrl.name= values;
$ctrl.ok = function () {
$uibModalInstance.close('ok');
};
$ctrl.cancel = function () {
$uibModalInstance.dismiss('cancel');
};
});。 https://angular-ui.github.io/bootstrap/#!#modal
