问题描述

最近我正在学习angularjs.我以前使用过引导程序.使用jquery，我可以轻松更改模态组件位置的位置以使其垂直对齐.现在使用angularjs，似乎很难做到这一点.这是ui bootstrap modal的一个庞克链接，有人知道如何使其垂直对齐吗?

Recently I am learning angularjs. I have used bootstrap before. With jquery, I can easily change the position of the modal component position to make it vertical align. Now with angularjs, it seems not very easy to do that. Here is a plunker link of ui bootstrap modal, Does anyone know how to make it vertical align?

    <!doctype html>
    <html ng-app="ui.bootstrap.demo">
    <head>
        <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.0/angular.js"></script>
        <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.0/angular-animate.js"></script>

        <link href="//netdna.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet">
    </head>
    <body>
        <div ng-controller="ModalDemoCtrl">
            <script type="text/ng-template" id="myModalContent.html">
                <div class="modal-header">
                    <h3 class="modal-title">I'm a modal!</h3>
                </div>
                <div class="modal-body">
                    This is modal body
                </div>
                <div class="modal-footer">
                    <button class="btn btn-primary" type="button" ng-click="ok()">OK</button>
                    <button class="btn btn-warning" type="button" ng-click="cancel()">Cancel</button>
                </div>
            </script>
            <button type="button" class="btn btn-default" ng-click="open()">Open me!</button>
        </div>
    </body>
</html>

2.example.js

    angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
    angular.module('ui.bootstrap.demo').controller('ModalDemoCtrl', function($scope, $uibModal, $log) {

        $scope.items = ['item1', 'item2', 'item3'];

        $scope.animationsEnabled = true;

        $scope.open = function(size) {

            var modalInstance = $uibModal.open({
                animation: $scope.animationsEnabled,
                templateUrl: 'myModalContent.html',
                controller: 'ModalInstanceCtrl',
                size: size,
                resolve: {
                    items: function() {
                        return $scope.items;
                    }
                }
            });
        };
    });

    angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl',   function($scope, $uibModalInstance, items) {
        $scope.ok = function() {
            $uibModalInstance.close($scope.selected.item);
        };

        $scope.cancel = function() {
            $uibModalInstance.dismiss('cancel');
        };
    });

推荐答案

如果我正确理解了您的问题，则只需使用CSS即可实现垂直居中对齐.添加以下CSS:

If I understand your problem correctly, you can acheive the vertical center alignment just by using CSS. Add following CSS:

.modal {
  text-align: center;
  padding: 0!important;
}

.modal::before {
  content: '';
  display: inline-block;
  height: 100%;
  vertical-align: middle;
  margin-right: -4px;
}

.modal-dialog {
  display: inline-block;
  text-align: left;
  vertical-align: middle;
}

我已经设置了一个柱塞进行演示.

I have setup a Plunker forked from yours to make a demonstration.
