メモ: ローカルにドロップして保存(ファイル名付き)

function makeDraggableDownloadLink(text, mimeType, fileName) {
  var blob = new Blob([text], {type: mimeType}),
         a = document.createElement('a');
  a.appendChild(document.createTextNode("download"));
  a.setAttribute('download', fileName);
  window.URL = window.URL || window.webkitURL;
  a.href = window.URL.createObjectURL(blob);
  a.addEventListener("dragstart", function(e) {
    e.dataTransfer.setData("DownloadURL", [mimeType,fileName,this.href].join(':'));
  }, false);
  return a;
}

メモ: 直接クリップボードにコピー

//ie, chrome-extension???
document.execCommand("copy");

メモ: Clipboard API

  • Clipboard APIが使用できるChromeOpera 12.50の場合、コピー、カットすると自動的に元のpreに戻すことが可能
var listener = function(e) {
  var tx = document.createElement("textarea"),
    rect = this.getBoundingClientRect(),
    name, ret,
  closeListener = function(e) {
    switch(e.type) {
    case 'copy':
    case 'cut':
      var dataTransfer = e.clipboardData;
      dataTransfer.items.add(this.innerText, 'text/plain');
      cleanup(this);
      e.preventDefault();
      break;
    case 'keydown':
      if(e.keyCode=="27") { // ESC
        cleanup(this);
      }
      break;
    case 'dblclick':
      cleanup(this);
    }
  };
  tx.addEventListener('copy',     closeListener, false);
  tx.addEventListener('cut',      closeListener, false);
  tx.addEventListener("keydown",  closeListener, false);
  tx.addEventListener("dblclick", closeListener, false);
