#REGION_ID# for pagination

Question

Hi all,
I want to show on the pagination bar in the report the button "Go to first page".
I can change the report template. But when I use the substitution String #REGION_ID# I get the ID in the following format: Rxxxxxxxx.
But I need to get only numbers for the link: pg_R_xxxxxx:NO:pg_min_row=1&pg_max_rows=15&pg_rows_fetched=15
Is there any way to solve this?

Hello Leonid,
The #REGION_ID# is only available during page rendering and not after the page has been load. That means that you can't directly manipulate it using JavaScript, you need first to put it on the page. The principle is to put an initial broken link, using #REGION_ID#, and then fix it, using JS and a onload event.
First, you should duplicate the report template you are using, and use the new template for all your experiments.
The first page link should appear for the second set of records, and onward. This is a static link – always pointing to the first set of records – so you can add it in the "Previous Set Template" field, in the pagination section of the report template. The link should look something like this:
< a id="P1" href="f?p=&APP_ID.:&APP_PAGE_ID.:&SESSION.:pg_#REGION_ID#:NO&pg_min_row=1&pg_max_rows=10&pg_rows_fetched=10">Page 1We will use the "P1" id to identify the link on the loaded page, and fix it. On the page, you should define an onload code like the following: onload = fixLink('P1');
The related JS function should look something like this:
function fixLink(pId) {
   var elm = $x(pId);
   if (elm) {
     var brLink = elm.href;
     var newLink = brLink.replace(/:pg_R/,":pg_R_");
     elm.href = newLink;
}This function takes the original #REGION_ID# value, in its regular format – Rxxx…xx – and change it to the pagination format of R_xxx…xx.
Hope this helps,
Arie.
