但是问题是我想插入这些脚本
but the problem is that i want to insert these scripts
<script type="text/javascript">
document.oncontextmenu=new Function("return false");
</script>
和
and
<script type="text/javascript" src="www.xyz-abc.co.in/js/..../me.js">
</script>
在iframe加载内容后，此javascript应该合并到加载内容中，并应在正在加载的页面中运行.谁能建议我.我已经使用jquery进行了检查，但没有结果.
换句话说，我希望每个人都在iframe中运行一个脚本文件，并且每次将新内容加载到iframe中.
after iframe load the contents, this javascript should merge into the loading contents and should run in the page being loaded. could any one can suggest me. i have checked it using jquery but no results.
in other words i want to run a script file inside the iframe each and evry time new contents are loaded to iframe.
推荐答案
如果您拥有要构建的页面，那么您只需将脚本包括在该页面上.
您不能也不应将您的JavaScript注入到您不拥有的页面中.考虑一下安全隐患.那太傻了.
If you own the page which you are framing, then you simply put the script include on that page.
You can''t and shouldn''t be able to inject your javascript into a page not owned by you. Think about the security implications. That would be silly.
