最近我正在学习angularjs.我以前用过bootstrap.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.现在有了angularjs,这似乎并不容易.这是一个ui bootstrap模式的plunker链接,有谁知道如何使它垂直对齐？
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 $scope.items;
}
}
});
};
});
angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl',$uibModalInstance,items) {
$scope.ok = function() {
$uibModalInstance.close($scope.selected.item);
};
$scope.cancel = function() {
$uibModalInstance.dismiss('cancel');
};
});
如果我正确理解您的问题,您只需使用CSS即可实现垂直中心对齐.添加以下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;
}
我已经设置了一个从您的分叉的Plunker来进行演示.

希望这可以帮助.干杯!!
