Advanced Search using minivend + javascript
Some time ago, I posted a question on this mailing-list but did not get an
answer... I thought about it and finally figured out a solution...
One of you might have tried to customize a Search page with Minivend but felt
limited when allowing the user to customize the search fields/values using an
HTML Form... here is the answer to that problem;
The key here is to create a one-click search and POST-PROCESS the "HREF" value
before actually returning it to minivend. I find that method to be very flexible compared
to the Minivend's [process-search] method.
I provide a source code example from what you can derive your own page.
Here it is:

<script language="JavaScript">

function processForm(myLink)
{
var idx,str,val1,val2,retVal;
var popular,newProduct,awards,day_care;
var language,searchText,fieldName,designed;
var price,rangeMin,rangeMax;
language = document.srchForm.language;
searchText = document.srchForm.searchText;
fieldName = document.srchForm.fieldName;

retVal = true;

idx = designed.selectedIndex;
if( idx != 0 )
{
val1 = designed.options[idx].value;
str += "/su=no/sf=conception/se=" + val1;

}
/* parse the HREF value built by [area scan] to find the previous and next
