Question

我想在停药时使$uibModal模态透明，在停止拖动时使其不透明。

目前，我在可拖动停止事件和mouseup()方法上尝试了jQuery fadeTo()和fadeIn()方法。模态变得透明但不会变得不透明。

我该怎么做这个动画？ The plunker

.directive('uibModalWindow', [function() {
  return {
    link: function(scope, element, attr) {
      console.log('element', element);
      var dialog = element.find('.modal-dialog');
      dialog.draggable({
        handle: '.modal-header',
        drag: function() {
          $(this).fadeTo(1000, 0.8);
        },
        stop: function() {
          $(this).fadeTo(1000, 1);
          //$(this).fadeIn();
        }
      });
      $('.modal-header').mouseup(function() {
        dialog.fadeTo(1000, 1);
        //dialog.fadeIn();
      });
    }
  };
}]);

您无需附加 mouseup 事件，只需在拖动事件结束时将不透明度重置为100％。

指定模态窗口必须位于页面所有其他元素的前景中也可能很有用，为此，只需将属性moveToTop设置为true。

请参阅以下内容：

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,
      keyboard: false,

    });

    modalInstance.result.then(function (selectedItem) {
      $scope.selected = selectedItem;
    }, function () {
      $log.info('Modal dismissed at: ' + new Date());
    });

  $scope.toggleAnimation = function () {

})
.directive('uibModalWindow', ['$document', function($document) {

      var dialog = element.find('.modal-dialog');
      dialog.draggable({
        handle: '.modal-header',
        moveToTop: true,
        drag: function() {
          $(this).fadeTo(10, 0.5);
        },
        stop: function() {
          $(this).fadeTo(10, 1);

还有opacity选项可以在拖动时为jQuery draggable定义不透明度：

  dialog.draggable({
    handle: '.modal-header',
    opacity: 0.5
  });

拖动时更改uibModal透明度
