Hi Joel, following a link meaans that the page is expected to change (I think this is a default assumption). And doing it by changing the existing page instead of forcing a new window is a good technique. (It is possible to use HTML that offers a new window, but have a user agent that doesn't open the new window, instead sticking to the original...) cheers Charles On Fri, 10 Nov 2000, Joel Sanda wrote: Hi all - I have a question about the accessibility of user controls that automatically update a page. Some search engines will allow a user to click on a button or link called "more" to retrieve additional information about the search result in question. Often this will load a new page with the description or a JavaScript function to pop-up a second window. My question is this: is there a problem with using that technique to load additional information in the same page with a server-side language, thereby avoiding the issues of JavaScript? The function could load additional information on the search result from the database and post the information below the result the user wanted more information about. This means the page will reload but retain the original list of search results with the additional information posted below the "parent" result. I suppose this could cause a conflict with WCAG #6.2, though I'm unsure of how this technique applies to that checkpoint. Checkpoint 10.1 states to "not change the current window without informing the user". My hunch is the button "more information" would alert the user that the content is to change. Using this technique could make large chunks of data - like search engine results - more manageable if the user is listening to the results. Thanks for any feedback!
