不能调用方法'split'的定义

Cannot call method 'split' of undefined

本文关键字：定义 split 调用 不能 方法      更新时间：2023-09-26

我已经创建了一个无限旋转木马。我想在选择图像时显示某些文本，但我一直得到以下错误信息:无法使用以下脚本调用未定义的方法'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">
    <div id="foo1">

旋转木马似乎在旋转，而不是显示正确的文本

<script type="text/javascript" src="/wp-content/themes/child/script/jquery.jcarousel.min.js"></script>
<script type="text/javascript" src="/wp-content/themes/child/script/carouFredSel.js"></script>
<script type="text/javascript">
jQuery(document).ready(function() {
    var imgLength = jQuery('ul#fredsel img').length;
    jQuery('#totalImg').html(imgLength);
    jQuery('#imgCount').html(1);
    // Using custom configuration
jQuery("#foo1").carouFredSel({
    items: 1,
    align: false,
    auto    : false,
    width: 1500,
    onCreate: function(items) {
        var txt = "";
        items.each(function() { txt += "<li>" + jQuery(this).attr("alt").split("/").pop() + "</li>"; });
        jQuery("#foo1_log").html("<p>Carousel created showing images:</p><ul>" + txt + "</ul>");
    },
    scroll  : {
    items           : 1,
    duration        : 1000,
    pauseDuration   : 2000,
        onAfter : function(oldItems, newItems) {
            var txt = "";
            newItems.each(function() { txt += "<li>" + jQuery(this).attr("alt").split("/").pop() + "</li>"; });
            jQuery("#foo1_log").html("<p>Now showing images:</p><ul>" + txt + "</ul>");
        }
    },
    prev    : {
        button  : "#foo1_prev",
        onBefore: function() {
            jQuery("#foo1_log").html("<p>Started scrolling to the <strong>left</strong>.</p>");
        }
    },
    next    : {
        button  : "#foo1_next",
        onBefore: function() {
            jQuery("#foo1_log").html("<p>Started scrolling to the <strong>right</strong>.</p>");
        }
    }
});
});
</script>
</head>

任何想法?

似乎你试图加载的一个或多个图像没有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>");
}

则jQuery(this).attr("alt")不是字符串或空
