JavaScript clears IFRAME content

Directly on the code bar:

document.getElementById ("MainFrame"). ContentWindow.document.body.innerText = "";

Some people on the web say that using content is actually incorrect, because content points to the content of the parent page and is incompatible. If you use Contentdocument, which is available under Google Chrome, is not compatible with IE, it is tested to visit Contentwindow first, and then access the document under it to be compatible with IE and chrome.
