Question

我（试图）从CDN加载jQuery 1.9.1：“Uncaught TypeError：无法调用未定义的jquery-1.9.1.js：648的方法'调用'”。所以我更新了参考文献，显然得到了一个等效的错误，现在用于缩小：

Uncaught TypeError: Cannot call method 'call' of undefined jquery-1.11.0.min.js:2
n.extend.each jquery-1.11.0.min.js:2
(anonymous function) site.js:26
j jquery-1.11.0.min.js:2
k.fireWith jquery-1.11.0.min.js:2
n.extend.ready jquery-1.11.0.min.js:2
K jquery-1.11.0.min.js:2

页面位于http://ccachicago.pragmatometer.com;第一个SCRIPT标签是：

<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>

（页面是POSH加上CSS样式和轻松的JavaScript尘埃;现代webapp标准很简单......）

- 编辑 -

关于我的代码，该页面只有脚本内容：

    <script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
    <script src="/media/js/site.js"></script>

        <script>
                        function slideshow()
            {
            var width = (jQuery(window).width()  - 70) * .8;
            var factor = width / 1024;
            var height = 420 * factor;
            jQuery('#slideshow').attr('height', height + 'px');
            jQuery('#slideshow').attr('width', width + 'px');
            };
        slideshow();
        jQuery(window).resize(slideshow);
        </script>

Answer 1

你的SYNxis不正确

你想做什么？

jQuery(function()
    {
    jQuery.each(jQuery('h1').add('h2').add('h3').add('h4').add('h5').add('h6').add('ul#navigation')).function(index, element)
        {
        var bounds = jQuery(element).offset();
        var image_left = bounds.left;
        var image_top = bounds.top + bounds.height;
        var image = jQuery('<img src="/media/images/foldback.png">');
        image.style.position = 'absolute';
        image.style.top = image_top + 'px';
        image.style.left = image_left + 'px';
        }
   function set_search_width()
        {
        var offset = 950;
        var width = jQuery(window).width() - offset;
        jQuery('#menu-search').css('max-width', width + 'px');
        jQuery('#menu-search').css('width', width + 'px');
        jQuery('#query').width(width - 80);
        }
    jQuery(window).resize(set_search_width);
    set_search_width();
    });

下面的代码可能是你想要的？（找到元素，我认为最好使用复杂的选择器，并将函数应用于每个元素）

jQuery('h1').add('h2').add('h3').add('h4').add('h5').add('h6').add('ul#navigation').each(function(index, element)
    {
    var bounds = jQuery(element).offset();
    var image_left = bounds.left;
    var image_top = bounds.top + bounds.height;
    var image = jQuery('<img src="/media/images/foldback.png">');
    image.style.position = 'absolute';
    image.style.top = image_top + 'px';
    image.style.left = image_left + 'px';
    });

Answer 2

违规行是：site.js line 26

如果应该像

那样

jQuery.each(jQuery('h1').add('h2'), function(index, element) { ... })

不

jQuery.each(jQuery('h1').add('h2')).function(index, element) { ... }
