I am trying to understand a bit of JavaScript from
http://developer.yahoo.com/maps/simple/jspost.html
(appended below). I'd
appreciate help understanding two things it. The first is the following:
<script type="text/javascript">
createForms();
</script>
I don't understand the "createForms()". I know it must be JavaScript but
I
have looked in the index of several references and do not find any such
entry in their indices. My online searches got a few hits but nothing
helpful. Where can I find some online doc for createForms()? It seems to
create a button labeled "View on Y! Maps" but where does that text (i.e.
"View on Y! Maps") come from?
The HTML also contains the following JavaScript:
document.write("<scr"+"ipt
language=javascript
src=http://l.yimg.com/us.js.yimg.com/lib/bc/bc_2.0.4.js></scr"+"ipt>");.
Why is the concatenation operator, +, being used here? To my naive mind
it
seems to be unnecessary.
I'll appreciate any help anyone can offer. Thanks, Bob
