我这样做但不工作：-
I am trying to insert the pixel in iframe and then append it to the body.
我正在尝试在 iframe 中插入像素，然后将其附加到正文中。
jQuery('#subscribr').append('<iframe>
<script language="javascript" src="http://www.abc/static/st.v2.js"></script>
<script language="javascript">
var ef_event_type="transaction";
var ef_transaction_properties = "ev_ProductViews=1";
/*
* Do not modify below this line
*/
var ef_segment = "";
var ef_search_segment = "";
var ef_userid="xxxx";
var ef_pixel_host="pixel.abc.net";
var ef_fb_is_app = 0;
effp();
</script>
</iframe>');

Scripts like that appear to break when </script>is included in the string. A workaround to that could be to add the elements through dom manipulation:
当</script>包含在字符串中时，像这样的脚本似乎会中断。解决方法可能是通过 dom 操作添加元素：
iframe = $('<iframe>');
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://www.abc/static/st.v2.js"; // Or:
script.text = "Your code here!"
iframe[0].appendChild(script);
iframe.appendTo('#subscribr'))

This is the solution which worked for me..
这是对我有用的解决方案..
var s = document.createElement("script");
s.type = "text/javascript";
s.src = "http://www.abc/static/st.v2.js";
// Use selector here
jQuery("#subscribr").append(s);

Working sample: http://fiddle.jshell.net/f2x7G/
工作示例：http: //fiddle.jshell.net/f2x7G/
var doc = null;
if(iframe.contentDocument) doc = iframe.contentDocument;
else if(iframe.contentWindow) doc = iframe.contentWindow.document;
else if(iframe.document) doc = iframe.document;
if(doc == null) throw "Document not initialized";
doc.open();
var script = doc.createElement("script");
script.type = "text/javascript";
// script.src = 'http://www.abc/static/st.v2.js';
script.text = "alert('voila!');"
doc.appendChild(script);
doc.close();
