用jquery动态嵌入youtube视频

Question

我试图检索用户的youtube视频列表并将它们嵌入到使用jQuery的页面中。我的代码看起来像这样：

$(document).ready(function() { 

    //some variables 
    var fl_obj_template = $('<object width="260" height="140">' + 
          '<param name="movie" value=""></param>' + 
          '<param name="allowFullScreen" value="true"></param>' + 
          '<param name="allowscriptaccess" value="always"></param>' + 
          '<embed src="" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="260" height="140"></embed>' + 
          '</object>'); 

    var video_elm_arr = $('.video'); 


    //hide videos until ready 
    $('.video').addClass('hidden'); 

    //pull video data from youtube 
    $.ajax({ 
    url: 'http://gdata.youtube.com/feeds/api/users/username/uploads?alt=json', 
    dataType: 'jsonp', 
    success: function(data) { 
     $.each(data.feed.entry, function(i,item){ 
     //only take the first 7 videos 
     if(i > 6) 
      return; 

     //give the video element a flash object 
     var cur_flash_obj = fl_obj_template; 

     //assign title 
     $(video_elm_arr[i]).find('.video_title').html(item.title.$t); 

     //clean url 
     var video_url = item.media$group.media$content[0].url; 
     var index = video_url.indexOf("?"); 
      if (index > 0) 
      video_url = video_url.substring(0, index); 

     //and asign it to the player's parameters 
     $(cur_flash_obj).find('object param[name="movie"]').attr('value', video_url); 
     $(cur_flash_obj).find('object embed').attr('src', video_url); 

     //alert(cur_flash_obj); 

     //insert flash object in video element 
     $(video_elm_arr[i]).append(cur_flash_obj); 

     //and show 
     $(video_elm_arr[i]).removeClass('hidden'); 
     }); 
    } 
    }); 
}); 

（当然用“用户名”是实际的用户名）。

视频标题显示正确，但没有视频显示。是什么赋予了？

目标HTML看起来像：

<div id="top_row_center" class="video_center video"> 
    <p class="video_title"></p> 
</div>

试试这个

变化：

var fl_obj_template = $('<object width="260" height="140">' +  
          '<param name="movie" value=""></param>' + 
          '<param name="allowFullScreen" value="true"></param>' + 
          '<param name="allowscriptaccess" value="always"></param>' + 
          '<embed src="" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="260" height="140"></embed>' + 
          '</object>'); 

这样：

var fl_obj_template = '<object width="260" height="140">' +  
          '<param name="movie" value=""></param>' + 
          '<param name="allowFullScreen" value="true"></param>' + 
          '<param name="allowscriptaccess" value="always"></param>' + 
          '<embed src="" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="260" height="140"></embed>' + 
          '</object>'; 

我认为正在使用的YouTube代码作为seletor
