swiper隐藏后再显示不会触发自动播放，加loop导致播放不正常

代码：点击huanj这个ul再显示swiper-container，默认swiper-container是隐藏的

..................................css...............................

.container{
    width:96%;
    margin:2% auto;
    position: relative;
display:none;

}

...................................页面.........................

  <ul class="huanj">

    <li><img src="/images/xueda/hj1.jpg"></li>
    <li><img src="/images/xueda/hj3.jpg"></li>

</div>

<script src="/js/swiper3.07.jquery.min.js" type="text/javascript"></script> 
    <script>
swiper1 = new Swiper('.swiper-container', {
    observer:true,//修改swiper自己或子元素时，自动初始化swiper
    observeParents:true//修改swiper的父元素时，自动初始化swiper
});


    </script>

.....................................................js ...................................

 $(".huanj").click(function(){

 $(".container").show();
 $(".huanj").hide();
  var mySwiper = new Swiper('.swiper-container', {  


        autoplay: 2500,
        autoplayDisableOnInteraction: false,
        pagination: '.swiper-pagination',
        paginationClickable: true,
       onSlideChangeEnd: function(swiper){ 
            swiper.update(); //swiper更新
