Javascript doesn't support multi-line strings, you'll need to either:
Javascript 不支持多行字符串，您需要：
- make that tag one big line, or
- use a trailing backslash on each line to indicate "continuation", or
- use multiple strings joined together.
- 把那个标签写成一条大线，或者
- 在每一行使用尾随反斜杠来表示“继续”，或
- 使用多个连接在一起的字符串。

I have copied and pasted the code into my machine. And I found the error.
我已将代码复制并粘贴到我的机器中。我发现了错误。
On line 4,
在第 4 行，
var video= '
<OBJECT ID="player" width="800" height="450" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" STANDBY="Loading Windows Media Player components..." TYPE="application/x-oleobject">
This is causing the error.
You have put a line break on line 4 after the equal to =sign.
Javascript considers every line break as new statement.
Please remove unnecessary line breaks and it should work.
这是导致错误的原因。您在第 4 行等号后放置了一个换行符=。Javascript 将每个换行符视为新语句。请删除不必要的换行符，它应该可以工作。
Thanks.
谢谢。

You can't assign multiline values to a variable in js, so you have to write it this way:
你不能在 js 中给变量赋值多行值，所以你必须这样写：
var video = '<OBJECT ...>';
video += '...';
But... the way you're creating an objectelement is not correct - you'd better use document.createElementfor more clear code.
但是...您创建object元素的方式不正确 - 您最好使用document.createElement更清晰的代码。
