Re: Create and get rid of frames page with Perl

It depends whether you know at the time of form submission whether you're going to want one frame or many. If you do, then it can almost certainly be done by targeting the link (at '_top', or '_parent', probably).

if you won't know that, as seems likely, then your output templates will have to be able to force framed and non-framed display. The way in is easy, as you've seen, but the only way to break out of a frame you're already in is with javascript. A universal 'frame me' and 'don't frame me' mechanism that lived at the top of each page would be quite simple to write, but a major pain in practice: that kind of thing disrupts history navigation, often fails when there's more than one domain involved and causes mouth ulcers.

can you really not use an inline mechanism instead? there aren't many frame-friendly tasks that can't be accomplished with either dhtml or the template toolkit, or both, and you'd save yourself a heap of misery. frames were a terrible kludge when they were new, and time has not been kind to them.

/me blushes quietly to recall how Modern it all seemed at the time

It is currently inline. The top 'frame' holds a small form and the bottom 'frame' holds a web page. The problem with this is that CSS on the web page is applied to the top 'frame' when it is inline. Use base solves the relative link issue but I could not stop the application of the CSS reliably. I just posted a pure Perl solution at Break into and out of frames pages with Perl CGI using _top I don't know if I will actually use it as I am not much of a frames fan either. cheers tachyon s&&rsenoyhcatreve&&&s&n.+t&"$'$`$\"$\&"&ee&&y&srve&&d&&print	[reply]
an aside about css that might help by thpfft (Chaplain) on Mar 29, 2003 at 20:11 UTC
css2 allows you to change the rule applied to an element according to the context in which you find it. eg. a rule in the form: `li em { ... }` [download] affects only em tags that are immediately contained by li tags. usefully, it works with ids as well as classes. If your original problem is that the formatting needed for the whole page is wrong for one or two elements in the header, then something in this form might work: `p { padding: 10px; ... } #header { border 1pt solid black; ... } #header p { padding: 0; ... }` [download] or it might not. You know. Just in case. All of which is heading pretty energetically away from the topic, but we could call it the mcfly method: travel back in time far enough and change something to make the problem go away :)	[reply] [d/l] [select]
