We wrote DOM classes previously for MacOS HTMLViewer, but as you now have 5 engines, we prefer to use JavaScript.
You are welcome to download MBS Plugins and try all the methods above.

[quote=470412:@Guenter Kraemer]So that wont help me at all.
I have a Win Desktop app, with a htmlviewer, and just want to fill the formfields and submit the form.
In Delphi, I use the document interface, exposed by the browser control, but I cant find something similar in the htmlviewer control.[/quote]
Christian is in error. ExecuteJavaScript is one of the methods of HTMLViewer DESKTOP.
I don’t suspect him of simply trying to sell his stuff. He probably forgot 😉

This one works
```auto
js = "document.forms[0].elements['your-name'].value=""test only"";"
HTMLViewer1.executejavascript(js)
```
but not the other
```auto
js = "document.getElementByName('your-name').value='test only';"
HTMLViewer1.executejavascript(js)
```
that give me an OELException

Sorry. When you search on the documentation page for ExecuteJavaScript, you end up only with the web entry: [ExecuteJavaScript](http://documentation.xojo.com/ExecuteJavaScript)
But now I found it: [HTMLViewer.ExecuteJavaScript](http://documentation.xojo.com/api/deprecated/htmlviewer.html#htmlviewer-executejavascript)
Still if you need a result, you better try our plugin.

I think that must be document.getElementsByName and returns an array, so you need the [0] there.
(in hope that IE supports it)

Do you control the content of the HTMLViewer? By this I mean, did you write the HTML and javascript in the HTMLViewer, or did some unknown person write it?

All depends on the structure of the DOM. I had assumed a simple input tag.At any rate, I am glad you found a way by yourself.
