blogとかで自分の書いた文字だけカウントしたためのプチスクリプト

jquery.writeowncount.js

(function($, undefined) {
  var digits = function(text) {
    return (text + "").replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,");
  };
  
  $.fn.writeowncount = function() {
    this.clone(true).each(function() {
      var $this = $(this);
      var ignore_tags = ["iframe", "a", "blockquote", "script", "div.gist", "pre"];
      var ignore_tag_str = ignore_tags.join(",");
      
      $this.find(ignore_tag_str).remove();
      
      console.log(digits($.trim($this.text()).length));
    });
    
    return this;
  }
}(jQuery));
