实现自动滚动

	doScroll: function () {
        var $parent = $('.js-slide-list');
        var $first = $parent.find('li:first');
        var height = $first.height();
        $first.animate({
            marginTop: -height + 'px'
        }, 500, function () {
            // 动画结束后，把它插到最后，形成无缝
            $first.css('marginTop', 0).appendTo($parent);
        });
    },



	setInterval(function () {
        _this.doScroll()
    }, 1997);
    
    
    

        <ul class="success js-slide-list" v-show="success.length">
        <li v-for="(item,index) in success" :key = index>
            <span>{{item.createTime}}</span>
            <span>{{item.status}}</span>
            <span>{{item.phoneNum}}</span>
        </li>  
    </ul>
