IE 抛出“未指定错误”重新加载嵌入了 swfobject 的页面时
我有一个简单的页面，上面嵌入了 swfobject。
看起来 IE 对嵌入对象的“过滤器”属性有问题。
我的测试页面如下所示：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>test</title>
<script type="text/javascript" src="../scripts/swfobject.js"></script>
<script type="text/javascript" src="../scripts/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
var url = "";
$(function()
{
var flashvars = {};
var parameters = {};
var attributes = {};
flashvars["data-file"] = url;
parameters.wmode = "transparent";
swfobject.embedSWF("test.swf", "graph1", "100%", "100%", "9.0.0", "expressInstall.swf", flashvars, parameters, attributes);
});
</script>
<style type="text/css">
#graph1
{
margin:30px;
height: 400px;
width: 600px;
}
</style>
</head>
<body>
<div id="graph1"></div>
</body>
</html>
注意： test.swf 文件是来自 下载页面。
现在，当我重新加载页面时，它会在 IE 上抛出“未指定错误”，但不会在 Firefox 上抛出“未指定错误”，其中过滤器属性设置为“未定义”。
似乎导致错误的代码位于 swfobject.js v2.2（第 494-504 行）中：
/*! SWFObject v2.2 <http://code.google.com/p/swfobject/>
is released under the MIT License <http://www.opensource.org/licenses/mit-license.php>
*/
function removeObjectInIE(id) {
var obj = getElementById(id);
if (obj) {
for (var i in obj) {
if (typeof obj[i] == "function") {
obj[i] = null; // when (i == 'filters') we get the error
}
}
obj.parentNode.removeChild(obj);
}
}
有谁知道为什么会发生这种情况？
I have a simple page with an swfobject embedded on it.
Looks like IE has problems with the 'filters' property on the embedded object.
My test page looks like that:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>test</title>
<script type="text/javascript" src="../scripts/swfobject.js"></script>
<script type="text/javascript" src="../scripts/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
var url = "";
$(function()
{
var flashvars = {};
var parameters = {};
var attributes = {};
flashvars["data-file"] = url;
parameters.wmode = "transparent";
swfobject.embedSWF("test.swf", "graph1", "100%", "100%", "9.0.0", "expressInstall.swf", flashvars, parameters, attributes);
});
</script>
<style type="text/css">
#graph1
{
margin:30px;
height: 400px;
width: 600px;
}
</style>
</head>
<body>
<div id="graph1"></div>
</body>
</html>
note: the test.swf file is the one swfobject package from the download page.
now when i reload the page, it throws an 'Unspecified error' on IE, but not on firefox in which the filters property is set to undefined.
the code that seems to cause the error is in swfobject.js v2.2 (lines 494-504):
/*! SWFObject v2.2 <http://code.google.com/p/swfobject/>
is released under the MIT License <http://www.opensource.org/licenses/mit-license.php>
*/
function removeObjectInIE(id) {
var obj = getElementById(id);
if (obj) {
for (var i in obj) {
if (typeof obj[i] == "function") {
obj[i] = null; // when (i == 'filters') we get the error
}
}
obj.parentNode.removeChild(obj);
}
}
Does anyone have any idea why this might be happening?

有两件事立即引起了我的注意：
第一：
您将匿名函数（包含 SWFObject 代码）包装在 jQuery 'dollar' 声明中。 jQuery Dollar 函数“接受包含 CSS 选择器的字符串，然后使用该字符串来匹配一组元素”。
您的函数不会返回任何内容，因此当 jQuery 尝试使用 null 引用作为 CSS 选择器时，它将导致 JavaScript 错误。
swfobject.embedSWF也不返回值，因此最好从代码中删除 jQuery Dollar 函数。如果您只想让代码在匿名函数中运行，请删除
$并在末尾添加函数调用：第二：
您传递的 FlashVars 变量名称包含连字符，这在 JavaScript 和 ActionScript 中都是非法的。
最后，
removeObjectInIE（swfobject.removeSWF的子函数）已在 IE 6、7 和 8 中经过全面测试。由于 IE9 仍处于测试阶段，swfobject 并未正式发布还是支持一下吧但是，我们预计不会出现任何问题。我建议尝试上面提到的编辑，看看是否可以解决您的问题。Two things that immediately caught my eye:
First:
You wrapped your anonymous function (containing the SWFObject code) in a jQuery 'dollar' declaration. The jQuery dollar function "accepts a string containing a CSS selector which is then used to match a set of elements."
Your function doesn't return anything, so it will cause a JavaScript error when jQuery tries to use a null reference as a CSS selector.
swfobject.embedSWFdoes not return a value, either, so it would probably be best to drop the jQuery dollar function from your code.If you just wanted your code to run in an anonymous function, drop the
$and add a function invocation at the end:Second:
You're passing a FlashVars variable name that contains a hyphen, which is illegal in both JavaScript and ActionScript.
Lastly,
removeObjectInIE(a subfunction ofswfobject.removeSWF) has been thoroughly tested in IE 6, 7, and 8. Since IE9 is still in beta, swfobject doesn't officially support it yet. However, we don't anticipate any issues. I suggest trying the edits I mention above and see if it clears up your issue.我不知道为什么会发生这种情况，但您可以尝试使用 try/catch 来修复它，
这应该可以避免错误消息。
I don't have an idea, why this happens, but you could try to fix it with a try/catch
This should avoid error messages.
