更新：动态替换JavaScript中嵌入标记的src属性

当我尝试更改embedded movie quicktime的src属性时，它奇怪地在Firefox中本地工作，但在Firefox的服务器上不工作，在Safari本地或服务器上都不工作，在IE中也不工作

我尝试下面的建议：

    $(".image_thumb ul li ul li").click(function(){     
var imgTitle = $(this).find('a').attr("href");  
var imgDesc = $(this).find('.block').html(); 
var imgDescHeight = $(".main_image").find('.block').height();   

if ($(this).is(".active")) {  
    return false; 
} else {
    alert(imgTitle);
    var videoClone = $(".main_image object").clone()
       .find("embed").attr({src: imgTitle}).end()  
       .find("param:first").attr({value: imgTitle});
    $(".main_image object").remove();
    $(".main_image").append(videoClone);

    $(".main_image .block").animate({ opacity: 0, marginBottom: -imgDescHeight }, 250 , function() {
        $(".main_image .block").html(imgDesc).animate({ opacity: 0.85,  marginBottom: "0" }, 250 );

    });
}
//more code

这根本不会让电影出现。除了电影，所有的东西都被加载了。有人知道为什么吗？当然，我不可能是唯一一个使用flash以外的东西来加载电影的人

html如果有帮助：

<div id="vid_wrapper">
    <div class="main_image">
        <object width="160" height="144"
        classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B"

感谢您的回复。

我还没有使用嵌入式对象，但我猜浏览器在加载src属性后不会对其更改做出响应

不知道这是否可行，但请尝试克隆对象，删除现有对象，更改克隆对象上的属性，然后将其添加回文档中

大概是这样的：

var videoClone = $(".main_image object").clone()
   .find("embed").attr({src: imgTitle}).end()  
   .find("param:first").attr({value: imgTitle});
$(".main_image object").remove();
$(".main_image").append(videoClone);

尝试设置参数wmode=transparent，然后执行z-index操作。

它不起作用。电影本身现在无法加载到页面上。在我最初的问题中，我更新了它。将电影放在divs中是唯一的解决方案。不能在JavaScript中动态更改嵌入标记的src属性。有一个新问题。这部电影在页面中的所有内容上都是分层的，即使我有一个菜单，可以在它前面设置动画。是否尝试设置菜单的z索引？是的，我试过了。我将两个的父div设置为relative。将电影div设置为99，将菜单div设置为100。还是一样的问题。
