Blogger and The Script Tag

By default, the blogger editor complains when you attempt to save a post with the <script> tag embedded inside of it. But as the content below shows, if you simply ignore the warning, it will indeed work just fine.

Even

As an aside: gosh I love Prototype. The above was written as:

<script>
 var words = ["using", "a", "src", "attribute", "on", "the", "script", "works." ];
 words.each(function(w) { document.writeln(w +  " "); });
</script>

You just have to love the use of anonymous functions and Lisp map like functionality. Sorry, couldn't resist.

Thanks to Digital Inspiration for the script tip.

    just to clarify, functions as first-class datatypes are thanks to core javascript, not prototype. combined with the ability to easily extend standard object types (like Array), the each/map function is basically trivial to write.

    all i'm driving at is that perhaps it should say "gosh i love javascript!" :) cheers.

    Good point.

    I do love JavaScript, and the ease in which you can extend basic objects in a painless manner.

    What I was driving at with Prototype (but of course didn't say well) was how with a single include, I can have access to not just array.each(), but a whole library of functions which make use of functions as first class citizens.

    So, maybe I should have said: "Gosh I love the way Prototype makes JavaScript more Lisplike without me having to do a bit of work."

    :-)

    Thanks for the comment.
