Removing iframe from page

Question

I am creating an iframe dynamically for submmiting a form,after submitting i need to remove the iframe form the page.I removed itas follows but it is not removed,

Answer 1

A way I've been doing it (since I have a large amount of iframes) is using jQuery,

$('iframe').remove()

or in the case of only one iframe you can remove it using its ID, still with jQuery

$('#iframeID').remove()
