Building on the answer to this question (see JSFiddle ), I have: 
基于此问题的答案 （请参阅JSFiddle ），我有：
var baseContent = '<!DOCTYPE html><html lang=\"en\"><head><title>..etc...</head><body>'+myContent+'</body></html>';
...and it works (produces the content of an iframe, in this case). ...并且可以正常工作（在这种情况下，产生iframe的内容）。 However, if I use the same procedure to add some javascript in the <head> (or <body> ), eg: 但是，如果我使用相同的过程在<head> （或<body> ）中添加一些javascript，例如：
<script type=\"text/javascript\">swfobject.embedSWF(\"flash.swf\", \"my_flash\");</script>
...I get error unterminated string literal at var baseContent = ' . ...我在var baseContent = '处得到错误unterminated string literal var baseContent = ' unterminated string literal 。 How do I include javascript in var baseContent ? 如何在var baseContent包含javascript？

@TamarG I tried the suggestions below but no luck - see: http://www.casedasole.it/fancybox/js/index.html . @TamarG我尝试了以下建议，但没有运气-请参阅： http : //www.casedasole.it/fancybox/js/index.html 。 I need to include in var baseContent both a link to an external javascript file (swobject.js) and its related javascript in the <head> . 我需要在var baseContent包括指向外部javascript文件（swobject.js）的链接以及<head>与之相关的javascript。 But adding <script type=\\"text/javascript\\" src=\\"swfobject.js\\"></script> to var baseContent stops the iframe loading, with the same error: unterminated string literal at var baseContent = ' . 但是，将<script type=\\"text/javascript\\" src=\\"swfobject.js\\"></script>到var baseContent停止iframe加载，但会出现相同的错误： var baseContent = '处unterminated string literal var baseContent = ' unterminated string literal 。
Explanation (reply to below) 说明 （回复下面）
The JSFiddle referred to in my question shows how fancybox can be used to open an iframe on page-load. 我的问题中提到的JSFiddle显示了如何使用fancybox在页面加载时打开iframe。 The content of the iframe is encoded in the "launch" page (unusual, because usually fancybox iframes load a separate HTML file, image, video etc). iframe的内容在“启动”页面中编码（不常见，因为通常是fancybox iframe会加载单独的HTML文件，图像，视频等）。
In the JSFiddle example, var baseContent contains a sample of HTML that can be used to create the iframe content ( <!DOCTYPE> , <head> , <style> <body> , etc). 在JSFiddle示例中， var baseContent包含一个HTML示例，可用于创建iframe内容（ <!DOCTYPE> ， <head> ， <style> <body>等）。 Encoding the basic HTML in var baseContent looks easy - eg <style type="text/css"> becomes <style type=\\"text/css\\"> . 用var baseContent编码基本HTML看起来很容易-例如<style type="text/css">变为<style type=\\"text/css\\"> 。
But I also need the iframe <head> to link to an external swfobject.js file and to include the standard 2-line swfobject flash detection script, swfobject.embedSWF("flash.swf", "my_flash" , etc. 但我还需要iframe <head>链接到外部swfobject.js文件，并包括标准的2行swfobject Flash检测脚本， swfobject.embedSWF("flash.swf", "my_flash"等）。
But when I use the same approach that works with the other HTML tags to encode the javascript tags, ie encode <script type="text/javascript" src="swfobject.js"></script> as <script type=\\"text/javascript\\" src=\\"swfobject.js\\"></script> , there is an error and the iframe won't open on page-load - see this page . 但是，当我使用与其他HTML标签一起使用的相同方法对javascript标签进行编码时，即将<script type="text/javascript" src="swfobject.js"></script>编码为<script type=\\"text/javascript\\" src=\\"swfobject.js\\"></script> ，出现错误，并且在加载页面时无法打开<script type=\\"text/javascript\\" src=\\"swfobject.js\\"></script> 请参见此页面 。
So my question is how to format links to external js files in var baseContent (and then, once that's working, how to format js in the var baseContent itself). 所以我的问题是如何在var baseContent格式化链接到外部js文件（然后，一旦工作，如何在var baseContent本身中格式化js）。

<script type=\\"text/javascript\\"> is to enter JS in html. <script type=\\"text/javascript\\">用于以html输入JS。 if the main code is JS - just remove <script type=\\"text/javascript\\"></script> and write only swfobject.embedSWF("flash.swf", "my_flash"); 如果主要代码是JS-只需删除<script type=\\"text/javascript\\"></script>并仅写入swfobject.embedSWF("flash.swf", "my_flash");
'<!DOCTYPE html><html lang=\"en\"><head><title>'+
swfobject.embedSWF("flash.swf", "my_flash")
+'</head><body>'+myContent+'</body></html>';
