A Javascript function used to extract meta description from an HTML document.

get_meta_description.js

/**
 * Returns document meta description
*/
getMetaDescription = function() {
  var metas = document.getElementsByTagName('meta');
  for(var i in metas) {
    if (typeof(metas[i].name) != 'undefined' && metas[i].name.toLowerCase() == "description") {
      return encodeURIComponent(metas[i].content);
    }   
  }
  return '';
}

Thank you for your time and effort
