[Helma-user] Server-side DOM

[Michael Platzer]

Hi,

We have been using the prototype.js on the server-side since over a year
now, but we always had to strip out the dom-related parts before
dropping it into the code-repository. That is a tempting  and impressive
idea, to try to just simulate the window/dom on the server-side.

But for running automated controller-tests, this doesn't bring that much
comfort compared to what jala already provides, does it?

Currently I can write
  var httpClient = new jala.Test.HttpClient();
  var result = httpClient.getUrl(someUrl);
  var doc = new jala.HtmlDocument(result.content);
  var ele = doc.scrape("//html:img[@id='captchaImage']"); //
XPath-expression

With env.js and prototype.js I could write
  window.location = someUrl;
  var ele = $("img.captchaImge");

But a lot of questions remain, like how would i simulate multiple
clients, or how can we support sessions, resp cookies?

Anyways, interesting article, thanks for the pointer!

p.s. looking at the above sample code, i would even simply suggest
adding methods '$' and '$$' to the jala.HtmlDocument. I don't think that
it would be that hard to implement these, since these are just simple
wrappers for the scrape-method?
