YouTube播放器的FF3/Windows CSS z-index问题

Question

我坚持看似与YouTube播放器的CSS/z索引冲突.在Windows XP下的Firefox 3中,请查看此页面:http://spokenword.org/program/21396单击"收集"按钮,并注意弹出的<div>显示在 YouTube播放器下方.在其他浏览器上,<div>显示在顶部.它的z-index值为999999.我尝试将包含播放器的<object>元素的z-index设置为较低的值,但这不起作用.知道如何让弹出窗口出现在播放器上吗？

Answer 1

尝试添加wmode参数opaque如下:

(请注意,它也包含在这两个一个<param>标签和一个wmode在属性<embed>标签.)

<object width='425' height='344'> 
    <param name='movie' value='http://www.youtube.com/v/Wj_JNwNbETA&hl=en&fs=1'> 
    <param name='type' value='application/x-shockwave-flash'> 
    <param name='allowfullscreen' value='true'> 
    <param name='allowscriptaccess' value='always'> 
    <param name="wmode" value="opaque" />
    <embed width='425' height='344'
            src='http://www.youtube.com/v/Wj_JNwNbETA&hl=en&fs=1'
            type='application/x-shockwave-flash'
            allowfullscreen='true'
            allowscriptaccess='always'
            wmode="opaque"
    ></embed> 
    </object>

虽然CMS的建议是有效的,但有一个重要的更新.如果你想使用'iframe'代替'embed',只需添加?wmode=transparent到你的视频链接即可.我觉得这更简单干净.

更新,2014年2月

已经有一段时间了,这可能已经过时了.

有人报告说现在&wmode=transparent有效.

我发现了一个纯JS功能,可以在所有浏览器中修复它!

你去的地方:

function fix_flash() {
    // loop through every embed tag on the site
    var embeds = document.getElementsByTagName('embed');
    for (i = 0; i < embeds.length; i++) {
        embed = embeds[i];
        var new_embed;
        // everything but Firefox & Konqueror
        if (embed.outerHTML) {
            var html = embed.outerHTML;
            // replace an existing wmode parameter
            if (html.match(/wmode\s*=\s*('|")[a-zA-Z]+('|")/i))
                new_embed = html.replace(/wmode\s*=\s*('|")window('|")/i, "wmode='transparent'");
            // add a new wmode parameter
            else
                new_embed = html.replace(/<embed\s/i, "<embed wmode='transparent' ");
            // replace the old embed object with the fixed version
            embed.insertAdjacentHTML('beforeBegin', new_embed);
            embed.parentNode.removeChild(embed);
        } else {
            // cloneNode is buggy in some versions of Safari & Opera, but works fine in FF
            new_embed = embed.cloneNode(true);
            if (!new_embed.getAttribute('wmode') || new_embed.getAttribute('wmode').toLowerCase() == 'window')
                new_embed.setAttribute('wmode', 'transparent');
            embed.parentNode.replaceChild(new_embed, embed);
        }
    }
    // loop through every object tag on the site
    var objects = document.getElementsByTagName('object');
    for (i = 0; i < objects.length; i++) {
        object = objects[i];
        var new_object;
        // object is an IE specific tag so we can use outerHTML here
        if (object.outerHTML) {
            var html = object.outerHTML;
            // replace an existing wmode parameter
            if (html.match(/<param\s+name\s*=\s*('|")wmode('|")\s+value\s*=\s*('|")[a-zA-Z]+('|")\s*\/?\>/i))
                new_object = html.replace(/<param\s+name\s*=\s*('|")wmode('|")\s+value\s*=\s*('|")window('|")\s*\/?\>/i, "<param name='wmode' value='transparent' />");
            // add a new wmode parameter
            else
                new_object = html.replace(/<\/object\>/i, "<param name='wmode' value='transparent' />\n</object>");
            // loop through each of the param tags
            var children = object.childNodes;
            for (j = 0; j < children.length; j++) {
                try {
                    if (children[j] != null) {
                        var theName = children[j].getAttribute('name');
                        if (theName != null && theName.match(/flashvars/i)) {
                            new_object = new_object.replace(/<param\s+name\s*=\s*('|")flashvars('|")\s+value\s*=\s*('|")[^'"]*('|")\s*\/?\>/i, "<param name='flashvars' value='" + children[j].getAttribute('value') + "' />");
                        }
                    }
                }
                catch (err) {
                }
            }
            // replace the old embed object with the fixed versiony
            object.insertAdjacentHTML('beforeBegin', new_object);
            object.parentNode.removeChild(object);
        }
    }
}

现在你可以在用jQuery加载页面时运行:

 $(document).ready(function () {
            fix_flash();    
 });
