I have a page that takes a parameter: http://example.com/mypage.html?param=123
Inside the html I have an iframe that needs that parameter, something like that:
<iframe src="http://example.com/myapp?id=123" etc...>
Now I know how to parse the parameter from the url, and I can change the src for the iframe in the onload(). But the problem is that iframe is first displays w/o the parameter (that displays some default iframe), then after onload it will display correctly.
Can I show the iframe with the parsed parameter right at load time? (No php, javascript only)
