请教如何让$.Dialog弹出后自动关闭

脚本出错了好不    $(function () {
        $("#happytime").on('click', function () {            $.Dialog({
                overlay: true,
                shadow: true,
                flat: true,
                draggable: true,
                icon: '<span class="icon-smiley fg-violet"></span>',
                title: '放松一下.',
                width: 275,
                content: '',
                onShow: function (_dialog) {
                    var content = _dialog.children('.content');
                    content.html('<br>您一定能在心里感受到我的热忱.<br><br>对把.');
                    console.log(_dialog);                }            });
////////////
            setTimeout(function () {
                $.Dialog('close');            }, 5000);        });
    });
