Mobile Pagination Prototype

Hi,

The mobile version of forums lack a means to jump to a specific page, unless you know the formula. I took it upon myself to attempt writing a script which would display each page in a topic, so you could easily jump to it.

This is the result :

* A first and last button to quickly jump to the beginning or end of a topic
* A list of pages that you can scroll through with the black block arrows

Script :
Administration Panel > Modules > JavaScript codes management > Create a new script

Placement : In the topics

Code:

$(function() {
  var perpage = 15, // amount of messages before a new page is added
  p = document.getElementsByTagName('P'), l = window.location.pathname, current, last, tid = l.replace(/\/t(\d+).*/,'$1'), tname = l.replace(/(\/t\d+|\/t\d+p\d+)(-.*)/,'$2'), style = document.createElement('STYLE'), css = '.pagi {height:auto;color:#FFF;position:static;margin:2px}.pagactif{color:#FF8;cursor:default}.scroller{position:absolute;width:18px;height:28px;cursor:pointer}.left.scroller{background:url(http://2img.net/i/fa/mobile/inner-left-arrow.png) no-repeat center #444;left:65px}.right.scroller{background:url(http://2img.net/i/fa/mobile/inner-right-arrow.png) no-repeat center #444;right:65px}', i,j;

  if (typeof _userdata.page_desktop === 'undefined') return;
  style.type = 'text/css';
  if (style.styleSheet) style.styleSheet.cssText = css;
  else style.appendChild(document.createTextNode(css));
  document.getElementsByTagName('HEAD')[0].appendChild(style);
 
  for (i=0; i<p.length; i++) {
    if (/mobile_title_content/.test(p[i].className)) {
      current = Number(p[i].innerHTML.replace(/Page <strong>(\d+)<\/strong> of <strong>\d+<\/strong>/i,'$1'));
      last = Number(p[i].innerHTML.replace(/Page <strong>\d+<\/strong> of <strong>(\d+)<\/strong>/i,'$1'));
    }
  }

  if (last >= current) {
    var b = document.getElementsByTagName('DIV'), title = document.createElement('DIV'), cen = document.createElement('DIV'), left = document.createElement('DIV'), right = document.createElement('DIV'), c = 1, d = 0;
    title.className = 'mobile_title', left.className = 'left scroller', right.className = 'right scroller', cen.className = 'mobile_title_content', cen.setAttribute('style','left:85px;right:85px;text-overflow:clip;line-height:26px;');
    for (j=0; j<b.length; j++) if (/mobile_title/.test(b[j].className) && /\d+/.test(b[j].nextSibling.id)) b[j].parentNode.insertBefore(title,b[j].nextSibling);
    title.appendChild(cen), title.appendChild(left), title.appendChild(right);
  
    left.onmousedown = function() { cen.scrollLeft -= 100 };
    right.onmousedown = function() { cen.scrollLeft += 100 };

    while (d < 2) {
      if (d == 0 && current > 1) newPage('mobile_prev_button block', '<p>First</p>', '/t' + tid + tname, title);
      else if (d == 1 && current != last) newPage('mobile_next_button block', '<p>Last</p>', '/t' + tid + 'p' + Number(perpage * last - perpage) + tname, title);
      d += 1;
    } while (last + 1 > c) {
      if (c == current) newPage('mobile_next_button block pagi pagactif', c, 'javascript:void(0);', cen, 'currentPage');
      else newPage('mobile_next_button block pagi', c, '/t' + tid + 'p' + Number(perpage * c - perpage) + tname, cen);
      c += 1;
    }
    cen.scrollLeft = document.getElementById('currentPage').offsetLeft;
  }
  function newPage(classname, html, href, par, id) {var page = document.createElement('A'); page.className = classname, page.innerHTML = html, page.href = href, par.appendChild(page); if (id) page.id = id}
});

You must change the 15 in var perpage = 15 to the amount of messages you allow perpage. ( Visible here : Administration Panel > General > Messages and e-mails > Configuration )



I could not do major testing as I don't have a mobile device, but if any of you want to test it, feel free !

If you're using a language other than english

These regular expressions will need to be translated in the script so it works properly :

Code:

     current = Number(p[i].innerHTML.replace(/Page <strong>(\d+)<\/strong> of <strong>\d+<\/strong>/,'$1'));
      last = Number(p[i].innerHTML.replace(/Page <strong>\d+<\/strong> of <strong>(\d+)<\/strong>/,'$1'));

wow, great job!
