Dynamic Javascript and CSS Primer Tutorial
The Head tag of an HTML webpage can be thought of as containing …
- Javascript scripting (though other types may work too)
- CSS (Cascading Style Sheets)
… as well as optional meta tags and title tag … and am sure you are not surprised that the CSS can be dynamic in a similar way to the methods used to make the (Javascript) scripting we showed you yesterday with Dynamic Javascript Primer Tutorial as shown below.
Without Javascript web pages would be pretty mundane, and without CSS you’d have a head falling off your hand holding it up (witty, huh?!), but the use of Javascript DOM and various Javascript libraries like jQuery or YUI make it a very dynamic world for our HTML webpages, as well as those CSS3 “smarts” out there for so many styling methods for your web work.
Normally what you do with your Javascript and CSS (ie. (usually) most of the Head tag) is all thought out and coded (beforehand) just the once, ready to use in your web pages. However, you can dynamically add Javascript and/or CSS of the user’s choosing into the web page’s script in the <head> … </head> should you be of a mind to want to do this, and today we take on that (dual) task.
We got great help with ideas on this, today, from this very useful link … so, thanks for that.
Tried various other approaches, unsuccessfully, before what was arrived at with our HTML source code you could call dynamic_javascript_iframe.html used today (and changed from yesterday’s code as per this link), and perhaps the reason for the lack of success revolved around care you need to take with the cache (unintentionally) interfering with arrangements where you remain on the webpage you are on using just DOM techniques.
Anyway, the whole thing was a layer of intrigue onto “intriguing”, and maybe the methods used can help you with an “onion of the 4th dimension” type of problem you have. Try a live run, and hope it helps in some way. As an idea of what you might try in the textarea as a test, you could try textareaidea.txt where the parent webpage is changed, as are all the child iframe HTML elements.

Javascript is the HTML scripting language … it’s official in HTML5 where the “type=’text/javascript'” in <script type=’text/javascript’> … </script> is no longer needed.
