I don't know if you still use this script? But if you still maintain it I made a fix or two to the "projection" of the page span slider … Ehrm, it's a bit involved but here we go (example with 25 pages, 10 page span):

In the original code you had the effect that the slider was well outside of the current page mark before the pages actually moved (actually it was half the width of the current page marker outside). Conversly you had the problem that in the end, when approacing 25, you would get to the place where the "border" of element 24 was on the slider (that is where you knew it was just going to show 24 as the last page in the list) and then it jumped to the end, hugging the wall.

Both problems were fixed with these changes to drawPages() (I only put the changed rows here):

var percentFromLeft = (this.html.scrollThumb.xPos+(this.html.pageCurrentMark.widthActual/2))/(this.html.table.offsetWidth);
/* The addition of half of the current page mark width solves the problem in the beginning */
var cellFirstValue = Math.round(percentFromLeft * (this.inputData.pagesTotal+1));
/* Simulating an extra page here takes care of one half of the other problem */
…
} else if(cellFirstValue >= (this.inputData.pagesTotal+1 - this.inputData.pagesSpan)) {
/* Here two we simulate an extra page to make the passing from 23 to 24-25 work */

You can see these changes in effect on my homepage: http://www.alajv.se/gotlands/ near the bottom … Also in your demo .html in the rar the 50 page example says 25 but is 50 ;o)

Thank you for a very nice script! Also, please hit me back by mail if you can …

Буду благодарен если ответите на е-мейл или тут.

Спасибо!
