Here you go:

var iframe;

iframe = document.createElement('iframe');
iframe.src = 'http://example.com/file.zip';
iframe.style.display = 'none';
document.body.appendChild(iframe);

Your code doesn't work because you're passing an entire HTML string into the createElement function ("jQuery style" :)), which is invalid. The valid parameter for this function is a string representing the tag-name (like 'div', 'iframe', 'p', etc.).
