我创建了一个infinte轮播。我希望在选择图像时显示某些文本但我不断收到以下错误消息：无法使用以下脚本调用undefined方法'split'
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('.set1').each(function() {
jQuery(this).before('<span>Some Text put here with Javascript... </span>');
});
});
</script>
<div class="image_carousel">

有什么想法吗？
答案 0 :(得分：0)
您尝试加载的一个或多个图片似乎没有alt属性。试试这个：
onAfter : function(oldItems, newItems) {
var txt = "";
newItems.each(function() {
var alt = jQuery(this).attr("alt") || "";
txt += "<li>" + alt.split("/").pop() + "</li>";
});
jQuery("#foo1_log").html("<p>Now showing images:</p><ul>" + txt + "</ul>");
}

然后jQuery（this）.attr（“alt”）不是字符串或空
