使用css或js关闭时如何将bootstrap 4模式对话框向右滑动

Question

我有一个引导模式，我应用 css 动画在打开时从右侧滑入，效果很好，但我想在单击自定义关闭按钮时将其滑回右侧，而不是在没有动画的情况下隐藏。

请任何人知道我如何做到这一点，已在网上搜索，但我看到的只是如何在打开时应用动画。

function customOpen(element){
  $(element).modal({
    backdrop: false,
    keyboard: false
  });
}
function customClose(element){
  $(element).modal('hide');
}
$(document).on("click", "#open", function() {
  var elem = $(this).attr("data-element");
  customOpen(elem);
});
$(document).on("click", "#close", function() {
  var elem = $(this).attr("data-element");
  customClose(elem);
});

.modal.fade {
    transition: opacity .0s linear !important;
}
.modal.fade:not(.show).left .modal-dialog {
	-webkit-transform: translate3d(-125%, 0, 0);
	-ms-transform: translate3d(-125%, 0, 0);
	-o-transform: translate3d(-125%, 0, 0);
	transform: translate3d(-125%, 0, 0);
}
.modal.fade:not(.show).right .modal-dialog {
	-webkit-transform: translate3d(125%, 0, 0);
	-ms-transform: translate3d(125%, 0, 0);
	-o-transform: translate3d(125%, 0, 0);
	transform: translate3d(125%, 0, 0);
}

只需使用自定义类modal-right并相应地更改transform其属性即可modal-dialog。默认情况下应用 Bootstrap top。

.modal.fade.modal-right .modal-dialog {
  transform: translate(125%, 0px);
}

.modal.show.modal-right .modal-dialog {
  transform: none;
}
