how reset margin of image animation in jquery easing plugin? i'm trying animate image using jquery easing plugin (see http://gsgd.co.uk/sandbox/jquery/easing/) allow image fly left right on click of link of page. tried this:

js

  $(".section-rates-go").click(function gorightease(){                 var initalleftmargin = $( ".innerliner" ).css('margin-left').replace("px", "")*1;        var newleftmargin = (initalleftmargin - 285); // 2 border        $( ".innerliner" ).animate({ marginleft: newleftmargin }, 4000, 'easeoutbounce');                       }) 

css

  .animation-mycontainer{        box-sizing: border-box;       white-space: nowrap;       overflow-x: hidden;       width: 280px;      }   .animation-box{        box-sizing: border-box;       display:inline-block;        width: 278px;       height: 148px;       vertical-align:top;        background-color:white;   } 

html div navbar:

<div id="nav"> <ol class="nav navbar-nav navbar-right text-right">         <li>                 <a href="#section-home">         <span>home</span></a></li>         <li>                 <a href="#section-services">         <span >services</span></a></li>         <li>                 <a href="#section-rates-go" class="section-rates-go">         <span>rates</span></a></li>         <li class="hidden-sm hidden-xs"> </ol></div> 

for image animation:

<div class="animation-mycontainer">                             <div class="innerliner">                               <span class="animation-box">                                </span>                               <span class="animation-box">                                <img src="./content/img/car-big1.jpg" width="270"/>                               </span>                             </div>                           </div> 

the problem is, if click more 1 time on "rates" in navbar, image shifts each time. want rese left margin initial position on click on "rates". how can achieve that? tried assign initalleftmargin initalleftmargin = initalleftmargin + 285; seems it's not resetting left margin of image. suggestion appreciated.
