iframe与document.write

Question

I need to insert the ad code with the document.write. But it overwrites the entire page. The script has the following form:

<script>
document.write.// some code
</script>

Tell me, please, how best to insert it? I think to use iframe, but maybe there are better methods. It possible to write it inside the iframe, like: <iframe><script>somecode</script></iframe> ? We use AdFox, so the script should be without any libraries.

Thanks for your help!

Answer 1

document.write overwrites everything after the page has loaded (after the document is ready). The best solution would probably depend on the nature of the ad. If it is very simple (eg a single image), try document.createElement To make elements and then add them to parent elements with Parent.appendChild .

If the ad is more complex, do you have a given "parent node" where all your code can be added? If so, simply do parent.innerHTML = your_html_code .

Also, iframes do not work that way. They do not allow you to insert any random code by placing it inside the iframe tags. In fact, the content inside tags only show when the browser does not support the element . You have to have a source url from which to do it. For reference, see MDN .
