我试图使用正则表达式修复闪光重叠。这是一个尝试转换为我的需求的标记示例
<object width="440" height="300" data=
"http://www.youtube.com/v/dMH0bHeiRNg&color1=0xb1b1b1&color2=0xd0d0d0&hl=en_US&feature=player_embedded&fs=1"
type="application/x-shockwave-flash">
<param name="allowScriptAccess" value="never" />
<param name="allowNetworking" value="internal" />
<param name="wmode" value="window" />
<param name="movie" value=
"http://www.youtube.com/v/dMH0bHeiRNg&color1=0xb1b1b1&color2=0xd0d0d0&hl=en_US&feature=player_embedded&fs=1" />
<!--[if IE]><embed width="440" height="300" src="http://www.youtube.com/v/dMH0bHeiRNg&color1=0xb1b1b1&color2=0xd0d0d0&hl=en_US&feature=player_embedded&fs=1" allowScriptAccess="never" allowNetworking="internal" wmode="window"><![endif]-->
</object>
我想要一个使用regluar表达式的函数
1)检查<param name="wmode" .....
的存在(如果存在)......它强制将值设置为'opaque'。如果不存在,则将其添加到上面的代码中。
我需要这个函数来解决保存在数据库中的'html'代码的闪存重叠问题

我通过在$(document).ready function。
中调用此函数(下面)来修复它window.fix_wmode2transparent_swf = function () {
// For embed
jQuery("embed").each(function(i) {
var elClone = this.cloneNode(true);
elClone.setAttribute("WMode", "Transparent");
jQuery(this).before(elClone);
jQuery(this).remove();
});
// For object and/or embed into objects
jQuery("object").each(function (i, v) {
var elEmbed = jQuery(this).children("embed");
if(typeof (elEmbed.get(0)) != "undefined") {
if(typeof (elEmbed.get(0).outerHTML) != "undefined") {
elEmbed.attr("wmode", "transparent");
jQuery(this.outerHTML).insertAfter(this);
jQuery(this).remove();
}
return true;
}
var algo = this.attributes;
var str_tag = '<OBJECT ';
for (var i=0; i < algo.length; i++) str_tag += algo[i].name + '="' + algo[i].value + '" ';
str_tag += '>';
var flag = false;
jQuery(this).children().each(function (elem) {
if(this.nodeName == "PARAM") {
if (this.name == "wmode") {
flag=true;
str_tag += '<PARAM NAME="' + this.name + '" VALUE="transparent">';
}
else str_tag += '<PARAM NAME="' + this.name + '" VALUE="' + this.value + '">';
}
});
if(!flag)
str_tag += '<PARAM NAME="wmode" VALUE="transparent">';
str_tag += '</OBJECT>';
jQuery(str_tag).insertAfter(this);
jQuery(this).remove();
});
}

我发现了一个纯JS功能,可以在所有浏览器中修复它!
你去吧: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();
}

您的代码中存在错误。有了修复,它的工作非常出色。代码将是
$(document).ready(function () {
fix_flash();
});
