i use Liferay.Util.openModal to popup a window

<aui:script position="inline" use="aui-base">
window.showEditSnmPrefixDialog2 = function(id) {
		Liferay.Util.openModal(
			{
				title: '<%=descriptionPrefixInfoEdit%>',
				centered: true,
                modal: true,
                height: 650,
				url: '<%=modifyPrefixURL.toString()%>&<portlet:namespace />targetPart='+id,
				size: 'md',
				id: '<portlet:namespace/>dialog'
			}
		);
}
</aui:script>

<aui:script>
    Liferay.provide(
        window,
        '<portlet:namespace/>closePopup',
        function(data, dialogId) {
            var A = AUI();
            var dialog = Liferay.Util.Window.getById(dialogId);
            dialog.destroy();
        },
        ['liferay-util-window']
    );
</aui:script>

    A.one('#<portlet:namespace/>closeDialog').on('click', function(event) {
