          /* Truncate the content of the P, then go back to the end of the
             previous word to ensure that we don't truncate in the middle of
             a word */
          trunc = trunc.substring(0, len);
          trunc = trunc.replace(/\w+$/, '');

             the paragraph back to its original size */
          trunc += '<a href="#" ' +
            'onclick="this.parentNode.innerHTML=' +

    What are you trying to accomplish?

    Can you use a plugin like http://wordpress.org/extend/plugins/excerpt-editor/
