Copy Paste Character

Two weeks ago we (me and Konst & Teknik) launched copypastecharacter.com—a site to make it dead easy to copy those special characters which otherwise can be hard to find. We just pushed an update and I realized I hadn’t mentioned it here.

The character you click will automatically get copied into your clipboard, thanks to the flash technique mentioned here. However, I wrote my own JavaScript class to handle the clipboard and the buffer of clicked characters since you can hold down ‹alt› to copy multiple characters at once.

Here’s the source for the copy buffer class in case anyone’s interested.

Multi-dimensional array sorter

The other day when working on some small updates on konst-teknik.se I wanted to sort the projects in a multi dimensional way, and take the other factors than the first into account. JavaScript’s Array#sort only supports one dimensional sorting so I wrapped my own sorter.

The results turned up pretty good (at least compared to the first test), or perhaps I just like recursing functions.

var sortOrder = {
  'cat-no': ['cat-no', 'name', 'type', 'year'],
  'name':   ['name',   'type', 'year', 'cat_no'],
  'year':   ['year',   'name', 'type', 'cat_no'],
  'type':   ['type',   'name', 'year', 'cat_no']
};

function sort(order) {
  var ordering = sortOrder[order], length = ordering.length;
  $$('#projects > li').sort(function(left, right) {
    left = Project.find(left), right = Project.find(right);
    return (function(index) {
      var a = left.getSortValue(ordering[index]),
          b = right.getSortValue(ordering[index]);
      return a < b ? -1 : a > b ? 1 :
        index < length ? arguments.callee(++index) : 0;
    })(0);
  }).each(function(project) {
    project.parentNode.appendChild(project);
  });
}
