[Htmlunit-user] Executing JavaScript 3

[<Gou...@ne...>]

Hello All!

Im trying to write tests for a pretty reach WebApp using HtmlUnit and i found out that there are a lot of things missing for JavaScript support. Currently I'm trying to add them: some I could do, some not.

The list of issues is here:
1: It is not possible to execute JavaScript function that takes href from an anchor, puts it as action of the form and submits the form than.

This I could fix: there was one (or two) method missing in com.gargoylesoftware.htmlunit.javascript.host.Anchor
I've added:
  import com.gargoylesoftware.htmlunit.html.HtmlAnchor;

  /**
    * Return the value of the href property.
    * @return The href property.
    */
  public String jsGet_href() {
      return ((HtmlAnchor)getHtmlElementOrDie()).getHrefAttribute();
  }

  /**
    * Set the href property.
    * Attention - this method was never tested!
    * @param href href attribute value.
    */
  public void jsSet_href( final String href ) {
      //((HtmlAnchor)getHtmlElementOrDie()).setHrefAttribute(href);
      //method setHrefAttribute is missing in API - think of to add it!
      ((HtmlAnchor)getHtmlElementOrDie()).getElement()
          .setAttribute("href", href);
      //workaround for missing setHrefAttribute method
      //please check if it works
  }

I did not neen jsSet_href method, so I didn't test it. It seems to be right and it compiles:)
jsGet_href is working an makes JavaScript execute right.

2: WindowOpen does not work (at least when JavaScript tries to set focus to the newely opened window).

I could not fix it, but I found out where the problem is:
com.gargoylesoftware.htmlunit.javascript.host.Window
  public static Object jsFunction_open(...) executes perfect till the last line, where it tries to do following:
  return (Window)newWebWindow.getScriptObject();
newWebWindow is a valid Object, but its getScriptObject() method returns null. So nothing else can be executed on the object returned from jsFunction_open, even jsFunction_focus() that does nothing.

I'm looking for a solution to set ScriptObject that is not null, that will be returned than by getScriptObject(). I guess something must create it ans than set it to the Window newWebWindow calling its setScriptObject() method.

Any idea?

3: I have a following line in JavaScript:
parent.<frame_name>.location.href=<some_value>;
this would produce following method calls stack (all in package com.gargoylesoftware.htmlunit.javascript.host):
jsGet_parent in Window
a call to get a frame by name - fails
jsGet_location in Window
jsGet_href in Location

All jsGet_XXX methods are doing right - I'm pretty sure.
I found out that the call to get frames is handled by
public Object get( final String name, final Scriptable start )
method in com.gargoylesoftware.htmlunit.javascript.SimpleScriptable, and it would even return a requested frame, if it would be set as a property.
But it is not set: I have modified the get method to print out some debug infos and found out, that SimpleScriptable stores all declared JavaScript functions as properties, but does not contain properties for frames.

I hope it is not much work to do something similar with frames as it is done with JavaScript functions. I would be obliged if someone would give me any idea what exactly should be done to fix it!

Best regards
