swiper刷新就跳转到下一个tab问题

Question

<script type="text/javascript">
    var chatSwiper = new Swiper('.swiper-container',{
        pagination: '.wechat-pagination',
        paginationClickable: true,
        history: true,
        paginationBulletRender: function (chatSwiper, index, className) {
           console.log(index);
            switch (index) {
                case {$i=0}:
                    name='<img class="wechat-img" src="__image__/mobile/talk.png" alt=""><img class="wechat-active-img" src="__image__/mobile/talk-active.png" alt=""><span class="wechat-text">会话</span>';
                    break;
                case {++$i}:
                    name='<img class="wechat-img" src="__image__/mobile/receive.png" alt=""><img class="wechat-active-img" src="__image__/mobile/receive-active.png" alt=""><span class="wechat-text">待认领</span>';
                    break;
                case {++$i}:
                    name='<img class="wechat-img" src="__image__/mobile/group.png" alt=""><img class="wechat-active-img" src="__image__/mobile/group-active.png" alt=""><span class="wechat-text">客户分组</span>';
                    break;
                {if $mine.level != 'service'}
                case {++$i}:
                    name='<img class="wechat-img" src="__image__/mobile/setting.png" alt=""><img class="wechat-active-img" src="__image__/mobile/setting-active.png" alt=""><span class="wechat-text">设置</span>';
                    break;
                {/if}
                case {++$i}:
                    name='<img class="wechat-img" src="__image__/mobile/person.png" alt=""><img class="wechat-active-img" src="__image__/mobile/person-active.png" alt=""><span class="wechat-text">我</span>';
                    break;
                default: name='';
            }
            let tt = '<li class="flex1 ' + className + '">' + name + '</li>';
            console.log(tt);
            return tt;
        }
    });

比如在会话这个导航 刷新当前页面就会自动跳转到待认领
