问题描述
最近我在学习 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，使其垂直对齐.现在使用 angularjs，似乎不太容易做到这一点.这是 ui bootstrap modal 的 plunker 链接，有谁知道如何使其垂直对齐?
ui 引导模态组件
1.index.html
<html ng-app="ui.bootstrap.demo"><头><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><script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-1.2.1.js"></script><script src="example.js"></script><link href="//netdna.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="样式表"><身体><div ng-controller="ModalDemoCtrl"><script type="text/ng-template" id="myModalContent.html"><div class="modal-header"><h3 class="modal-title">我是模态！</h3> <div class="modal-body">这是模态体
<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()">取消</button>
<button type="button" class="btn btn-default" ng-click="open()">打开我！</button>
</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 = 函数(大小){var modalInstance = $uibModal.open({动画:$scope.animationsEnabled，templateUrl: 'myModalContent.html',控制器:'ModalInstanceCtrl'，尺寸:尺寸，解决: {项目:函数(){返回 $scope.items;}}});};});angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl', function($scope, $uibModalInstance, items) {$scope.ok = function() {$uibModalInstance.close($scope.selected.item);};$scope.cancel = function() {$uibModalInstance.dismiss('cancel');};});
解决方案
如果我正确理解您的问题，您只需使用 CSS 即可实现垂直居中对齐.添加以下 CSS:
.modal {文本对齐:居中；填充:0！重要；}.modal::before {内容: '';显示:内联块；高度:100%；垂直对齐:中间；边距右:-4px；}.modal-dialog {显示:内联块；文本对齐:左；垂直对齐:中间；}我已经设置了一个 Plunker 从你的分叉出来进行演示.

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?
ui bootstrap modal component
1.index.html
<!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>
<script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-1.2.1.js"></script>
<script src="example.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');
};
});
解决方案
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;
}
I have setup a Plunker forked from yours to make a demonstration.
