动画Jquery弹出菜单

当用户点击链接时,我想让我的JQuery菜单有一个简单的动画。我有一个箭头指向点击的链接,但我希望箭头在点击之间设置动画。如果用户单击Link1,则箭头向右滑动,如果用户单击链接2,则箭头向左滑动。我知道我可以使用“.animate”。但是我无法让它发挥作用。

JQuery的

(function(){  

var closetimer = 0;
var menuitem = 0;
var arrow = $('.arrow');

function animate_right () {
   var ele = $('.a'); 
   var pos = ele.offset(); 
   var left = pos.left;
   var total = left+48;
   arrow.show().css('left', total);
}

function animate_left () {
   var ele = $('.b'); 
   var pos = ele.offset(); 
   var left = pos.left;
   var total = left+48;
   arrow.show().css('left', total);
}

function arrow_hide () {
   arrow.hide()
}

function flyout_open(event)
{
   flyout_close();
   var submenu = $(this).find('ul');
   menuitem = submenu.fadeIn(200);  
    if(submenu.hasClass('ul_a')){
        animate_right();

        return false;

    } else if (submenu.hasClass('ul_b')) {
        animate_left();

        return false;
    }

    return true;
}

function flyout_close()
{  arrow_hide(); if(menuitem) menuitem.fadeOut(200);}

$(document).ready(function()
{  $('#flyout li').bind('click', flyout_open);
});

(document).onclick = flyout_close;


})();

您可能希望将#flyout职位更改为亲戚:

#flyout{
    position : relative;
}
