Subject: SPUG: Ajax question - js args<BR>
<BR>
Hiya,<BR>
<BR>
<BR>
<BR>
I'm working with Ajax and have a real basic question. Meanwhile I'm going to<BR>
show what I'm doing in this Ajax example, because surely there will be<BR>
/(people)+/ that will find it intriguing or useful.<BR>
<BR>
<BR>
<BR>
My question is simply: How do I assign input arguments that are passed to a<BR>
.js file to variables in the js code? That's new to me, I think I've read ~ 42<BR>
million web pages looking for that simple building block, and no joy.<BR>
<BR>
<BR>
<BR>
Here's the example: <A HREF="http://www.eskimo.com/~ghawk/ajax/test.htm">http://www.eskimo.com/~ghawk/ajax/test.htm</A><BR>
<BR>
<BR>
<BR>
Once on the page, you'll see a little "rotating" animated gif while the<BR>
external page/information is being read. The Perl script triggered by the js<BR>
code is looking for the number of sellers on this page:<BR>
<A HREF="http://www.amazon.com/exec/obidos/ASIN/B000ERVJM2/">http://www.amazon.com/exec/obidos/ASIN/B000ERVJM2/</A><BR>
<http://www.amazon.com/gp/product/B000ERVJM2/ref=pd_ts_d_31/102-0990943-3824922<BR>
?s=dvd&v=glance&n=130> .where it says something like<BR>
<http://www.amazon.com/gp/offer-listing/B000ERVJM2/ref=dp_olp_2/102-0990943-382<BR>
4922?%5Fencoding=UTF8> 56 used & new (the number changes of course).<BR>
<BR>
<BR>
<BR>
Once Perl has retrieved that page and extracted the number, it is returned to<BR>
the javascript (the js file that was pulled in by the htm page), and Ajax sees<BR>
the package has arrived, updates the div (id is 'display') and places the<BR>
digits there, replacing the image.<BR>
<BR>
<BR>
<BR>
So, you might notice that in the javascript, I am sending an arg:<BR>
<BR>
<BR>
<BR>
<script language="javascript"<BR>
src="<A HREF="http://www.eskimo.com/~ghawk/ajax/test.js?a=B000ERVJKO">http://www.eskimo.com/~ghawk/ajax/test.js?a=B000ERVJKO</A>"></script><BR>
<BR>
<BR>
<BR>
...and that ASIN (Amazon Standard Identification Number) is different than the<BR>
one hardcoded (or medium coded) into the .cgi file. Now all I have to do is<BR>
persuade js to take in that arg so it can be handed over to the Perl script.<BR>
<BR>
<BR>
<BR>
In short, I need the js<BR>
<http://www.google.com/search?as_q=&num=100&hl=en&btnG=Google+Search&as_epq=js+<BR>
equivalent+of+@ARGV> equivalent of @ARGV.<BR>
<BR>
<BR>
<BR>
Thanks,<BR>
<BR>
