当该网址不允许在iframe中时，我需要重定向到该网址？

Question

as I can redirect to a page when this can not be shown in an iframe, for example google, if you do not load the iframe redirect google directly.

<script type="text/javascript">       
function redirect(iframe)
{
window.location = iframe.src;
}
</script>
<iframe src="http://www.google.com" onerror="redirect(this)"></iframe>

for security reasons (cross-browser functionality), You can't access elements in an iframe from a different domain with JQuery. you don't have access to any properties within an iframe.iframe probably isn't the best to rely on.
