 jQuery-Paging

We've seen a lot of pagination plugins on DailyJS recently, but diversity is good so I'll keep collecting them until somebody convinces me not to! jQuery-Paging (License: MIT/GPL, GitHub: infusion / jQuery-Paging) by Robert Eisele is another take on client-side pagination. Usage centres around the number of items to paginate:

$(selector).paging(itemCount, options);

The plugin will generate a list of links, and clicking a link will cause the onSelect method to fire, which is one of the plugin's many options. Formatting is handled in a relatively unique way -- a format string and formatting callback are used:

$('#pagination').paging(itemCount, {
  format: '[< ncnnn >]',

  onFormat: function(type) {
    switch (type) {
      case 'block': // n and c
        return '<a>' + this.value + '</a>';
      case 'next': // >
        return '<a>&gt;</a>';
      case 'prev': // <
        return '<a>&lt;</a>';
      case 'first': // [
        return '<a>first</a>';
      case 'last': // ]
        return '<a>last</a>';
    }
  }
});

This is an interesting solution to handling formatting in pagination plugins.

Robert has lots of other jQuery and HTML5 projects listed on his site, here: xarg.org/projects/.

 Pomodoro Timer App

Pomodoro Timer (GitHub: oivoodoo / pomodoro-app) by Alexander Korsak is designed to manage time using the Pomodoro Technique. It's implemented using Backbone.js and jQuery Mobile. It comes with a little wrapper that allows it to run on Heroku.

The Backbone.js code is carefully organised into collections, models, routers, and views. It serves as a good example of a self-contained Backbone.js application, particularly in terms of code organisation.

SAP's HTML5 UI Toolkit

That's right, you're seeing something made by SAP on DailyJS. I was initially sceptical when I saw their new HTML5 UI toolkit, and the tutorials are PDFs, which didn't help. However, when I saw the jQuery-style API I started to read more:

$(document).ready(function() {
  $('#uiArea').sapui('Button', 'btn', {
     text: 'Hello World!',
     press: function() { $('#btn').fadeOut(); }
  });
});

DailyJS reader Stefan sent this in, and he had a few comments about it that I thought I'd share:

Interesting side note: Their primary target for this is first tablets, then mobile then PCs and they will only support HTML5 (no fallbacks for older IEs).

From what I can gather, SAPUI5 uses jQuery, so it seems like the sapui method in the example is a plugin they've implemented for convenience. Unfortunately, downloading the beta requires an account, and even with a hastily created free account I couldn't get it to download. Regardless, I expect jQuery can now include SAP in their "who's using jQuery" list.
