CodePress Addons

I was playing around with CodePress. There are some modification I made:
This one updates all textareas fields when form is submited, and fix the problem with rails javascript tag hepler.

CodePress.run = function() {

  s = document.getElementsByTagName('script');

  for(var i=0,n=s.length;i    if(s[i].src.match('codepress.js')) {

      CodePress.path = s[i].src.replace(/codepress.js.*$/,'');

    }

  }

  t = document.getElementsByTagName('textarea');

  for(var i=0,n=t.length;i    if(t[i].className.match('codepress')) {

      id = t[i].id;

      t[i].id = id+'_cp';

      eval(id+' = new CodePress(t[i])');

      t[i].parentNode.insertBefore(eval(id), t[i]);

    }

  }

  f = document.getElementsByTagName('form');

  for(var i=0,n=f.length;i    cps = f[i].getElementsByClassName('codepress');

    if(cps.length > 0){

      f[i].cps = cps;

      f[i].onsubmit = function(){

        for(var i=0;i          this.cps[i].value = eval(this.cps[i].id.replace('_cp','')+'.getCode()');

          this.cps[i].disabled = false;

        };

      }

    }

  }

}
