javascript - Jquery 循环 : iterate siblings by four, 然后从头开始

Question

问:我如何创建一个循环来同时显示四个 div，它们是 #reviewswidget 的子级？一旦幻灯片放映结束，它需要返回到前四个 div。

<div id="reviewswidget">
    <div class="reviewtitle">title 1 goes here</div>
    <div class="reviewrating">rating 1 goes here</div>
    <div class="reviewreview"> review 1 goes here</div>
    <div class="reviewauthor">author 1 goes here</div>
    <div class="reviewtitle">title 2 goes here</div>
    <div class="reviewrating">rating 2 goes here</div>
    <div class="reviewreview"> review 2 goes here</div>
    <div class="reviewauthor">author 2 goes here</div>
</div>

我的尝试:

jQuery(function () {
        jQuery('#reviewswidget div').hide().slice(0, 4).show();
        setInterval(function () {
            jQuery('#reviewswidget div').filter(':visible').fadeOut(function () {
                self.setSliceIteration(4);
                self.setSliceTotal(jQuery('#reviewswidget div').length);
                if (self.getSlice() === 0 && self.getSlice() === '') {
                    jQuery('#reviewswidget div').hide().nextAll().slice(self.getSlice()).show();
                    self.setSlice(self.getSliceIteration() + self.getSlice());             
                }
                if (self.getSlice() < self.getSliceTotal()) {
                    $(this).nextAll().slice(self.getSlice()).show();
                    self.setSlice(self.getSliceIteration() + self.getSlice());
                }
                if (self.getSlice() < self.getSliceTotal()) {                   
                }
            });
        }, 3000);
    });
