Blog.okuryu : JavaScript-XPath for YUI part 2

TODO をオープンソース - IT戦記を見て、優先順位低すぎやなと思いつつ、前回に引き続き考察する。YUI 自体をいじるのはちょっとまずいのかなと思ったので、名前空間を作って JavaScript-XPath をラッピングしてみた。

<div class="content">content</div>
<div class="content">content</div>
<div class="content">content</div>
<script type="text/javascript" src="javascript-xpath-latest.js"></script>
<script type="text/javascript">
YAHOO_config = {
  load: {
    require: ['dom', 'event', 'logger'],
    base: 'http://yui.yahooapis.com/2.3.1/build/',
    onLoadComplete: function(loader) {
      YAHOO.widget.Logger.enableBrowserConsole();
    }
  }
}
</script>
<script type="text/javascript" src="http://yui.yahooapis.com/2.3.1/build/yuiloader/yuiloader-beta-min.js"></script>
<script type="text/javascript">
YAHOO.namespace('xpath');
YAHOO.xpath = function() {
  var _context, _position, _type;
  return {
    get: function(context, position, type) {
      _context = context || '/';
      _position = position || document;
      _type = type || 7;
      var x = document.evaluate(_context, _position, null, _type, null);
      var nodes = [];
      for (var i = 0, l = x.snapshotLength; i < l; i++)
        nodes.push(x.snapshotItem(i));
      return nodes;
    }
  };
}();
window.onload = function() {
  YAHOO.log(YAHOO.xpath.get('//div[@class="content"]').length); // 3
};
</script>

なんか本当にただのラッパーになってしまった。関係ないけど、YAHOO.log() は firebug の console.log() を実行するようにできるので便利。

Risky theme. I think you've hurt someone's feelings, but what's for me - I like it. No matter what they say if your opinion is true.

This whole situation is SO absurd. Your post strikes as serious for you only. What can we do but make jokes about it?
