为 Jquery Oembed 使用自己的处理程序

Question

我正在尝试使用自己的函数（从不喜欢 $(document).ready()）从 URL 动态加载嵌入。

我正在尝试这样：

function video(donde,url) {
    $("#"+donde).oembed(url);
    return false;
}

还有一个使用示例：

<div class="texto">
  [my title]
  <span style="float: right;">
      <img onclick="video('video68084','http://www.youtube.com/watch?v=ORZTCQjAuZY');" src="http://i1.ytimg.com/vi/ORZTCQjAuZY/default.jpg" alt="preview" onerror="this.src='images/linket.png';" class="caja_con_sombra" style="width: 80px; height: 60px;">  </span>
  <div style="float: left; width: 76%;">
       [my description]
  </div>
  <div id="video68084"></div>
</div>

哪个跳跃：

b.type is not a function
[Interrumpir en este error] b.ready);var j=false;try{j=E.frameElem...ow(j))return false;if(j.constructor&& 

Onclick 通过 firebug :(

知道我错过了什么吗？错误源文件是 jquery.min.js :S

您没有遗漏任何东西，您在 oembed 插件中发现了一个错误。很好的发现，也许你在质量保证方面有未来的职业:)

看起来 oembed 和 jQuery 都想使用 .type，但 jQuery 以 oembed 的字符串 .type 结尾，它想要自己的函数 .type。

oembed plugin 可以在 jQuery-1.3.2 中正常工作，但在 jQuery-1.4.3 中会中断。

您可以从此 jsfiddle 中提取 oembed 插件的功能版本：http://jsfiddle.net/ambiguous/ZVhUn/1/

这个问题一直是reported several times，但oembed作者似乎没有在听。如果需要，这里有一个固定版本的插件：

(function($) {
    $.fn.oembed = function(url, options, callback) {

        options = $.extend(true, $.fn.oembed.defaults, options);

        return this.each(function() {

            var container = $(this),
                resourceURL = (url != null) ? url : container.attr("href"),
                provider;

            if (!callback) callback = function(container, oembed) {            
                 $.fn.oembed.insertCode(container, options.embedMethod, oembed);
            };

            if (resourceURL != null) {
                provider = getOEmbedProvider(resourceURL);

                if (provider != null) {                        
                    provider.params = getNormalizedParams(options[provider.name]) || {};
                    provider.maxWidth = options.maxWidth;
                    provider.maxHeight = options.maxHeight;                                        
                    provider.embedCode(container, resourceURL, callback);
                    return;
                }
            }

            callback(container, null);
        });
    };

    // Plugin defaults
    $.fn.oembed.defaults = {
        maxWidth: null,
        maxHeight: null,

                    $.fn.oembed.insertCode(container, "replace", oembed);

唯一的变化是我在文件底部的this.embedCode 中将var oembed = $.extend(data); 替换为var oembed = $.extend({ }, data);。
