更新：动态替换 JavaScript 中嵌入标签的 src 属性

Question

当我尝试更改嵌入电影（quicktime）的 src 属性时，它在 Firefox 中奇怪地在本地工作，但在 Firefox 中的服务器上不起作用，在本地或服务器上的 Safari 中不起作用，并且它不起作用在IE中。

我尝试了下面的建议：

    $(".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

这根本不会使电影出现。除了电影之外，所有内容都已加载。有人知道为什么吗？当然，我不可能是唯一一个使用闪存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"

感谢您的回复。

Answer 1

我没有使用过嵌入对象，但我猜测浏览器在加载后不会响应 src 属性的更改。

不知道这是否有效，但尝试克隆对象，删除现有对象，更改克隆对象的属性，然后将其添加回文档中。

像这样的东西：

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..
