javascript - 如何在 iframe 标签中插入 javascript 代码

Question

我这样做但没有工作:-

我试图在 iframe 中插入像素，然后将其附加到正文。

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>');
enter code here

Answer 1

当 </script> 时，类似的脚本似乎会中断包含在字符串中。解决方法是通过 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'))
