Ok, here's a wide open question:
We are going back through our application and trying to introduce more Ajax where we can to dynamically add content when we can instead of reloading the entire page. Example: we often use a tabbed interface, and for performance reasons, we only load the content in the selected tab. When the user switches tabs, why reload the entire page just to change one part of it? We'll just do an Ajax call to get the content for that tab, and then innerHTML it in to where it would go. Well, this is great, but now one of the problems we are running in to is JavaScript libraries that we use all over the site. For instance, we have a nifty little calendar drop down custom tag we use. The calendar tag includes the JavaScript library it needs the first time it is called. Well, what if I am ajaxing in some content that has one of those calendar drop downs. How can I programmatically and consistently know whether the JavaScript library has already been loaded for it to work? I used to just set a request variable, but that doesn't really apply now since the original request scope doesn't exist anymore when I make my Ajax call, and furthermore, content could have been removed on the page SINCE it originally loaded. My first though was to load ALL JavaScript libraries ALL the time whether I needed them or not. I'm not so sure about that though, because it sounds like a waste of bandwidth and client memory usage. Is that a valid worry? My second thought was to load NONE of my JavaScript libraries off the bat, and then load them dynamically as needed. If I went this approach, I would need to either put an if statement around EVERY JS function call to check for it BEFORE I called it OR build a wrapper JS function and make EVERY JS call go through the wrapper. I would tell it what function I wanted to call, and my arguments. It would check for its existence and Ajax it in if necessary and THEN call it returning the result back to the original code. Am I making sense here? Has anyone tried this before? Are there any frameworks made for this? Am I over-thinking this? ~Brad ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Upgrade to Adobe ColdFusion MX7 Experience Flex 2 & MX7 integration & create powerful cross-platform RIAs http:http://ad.doubleclick.net/clk;56760587;14748456;a?http://www.adobe.com/products/coldfusion/flex2/?sdid=LVNU Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:268374 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
