Create link groups for search results or a view

How to create the link groups for search results or for a view with JavaScript.

This JavaScript function may be used to create the link groups for search results or for a view. For example:
Previous | 1 | 2 | 3 | Next

Input parameters: total - the total number of documents in the view or search result format - the format of the generated links 0 (or omitted) generates page numbers, ex. Previous | 1 | 2 | 3 | Next 1 generates groups, ex.. Previous | 1 - 4 | 5 - 8 | 9 - 10 | Next when you call the original view the URL should include two parameters: &count will be used to calculate the intervals &start must be the last parameter in the URL defaults &count=30&start=1 place call to this function on the $$...template at the spot where you want the links to appear set the total passed to this function to TotalHits or use @DBLookup to set it to the number of documents in the view Place it on any $$viewtemplate or $$searchtemplate and pass the total to it.

/* ----------------------------------------------

return middle of the string
example:
middle('&count=25&start=1&', 
'&count=', '&') 
will return:
'25'
------------------------------------------------

function middle(str, ina, inb){ // return 
middle of the string
//alert('middle function');
var startix = str.indexOf(ina);
var endix = str.indexOf(inb, 
startix + 1);
var newStr = '';
if (startix >= 0) { 
if (endix < 0) {endix = str.length;} 
newStr = str.substring(startix + 
ina.length, endix);
} else {newStr = ''; }
return newStr;

Generate links in groups
place this script on a $$viewtemplate 
or $$searchtemplate

Input parameters:
total - the total number of documents 
in the view or search result
format - the format of the generated links
0 (or omitted) generates page 
numbers, ex. Previous | 1 | 2 | 3 | Next 
1 generates groups, ex.. 
Previous | 1 - 4 | 5 - 8 | 9 - 10 | Next 
when you call the original view the 
URL should include two parameters:
&count will be used to calculate the
 intervals
&start must be the last parameter 
in the URL
defaults &count=30&start=1
place call to this function on 
the $$...template at the spot where 
you want the links to appear
set the total passed to this function 
to TotalHits or 
use @dbLookup to set it to the n
umber of documents in the view
