XMLHttpRequest-class is missing `response`-attribute

[markoandersson]

I think that there should be response-attribute in the XMLHttpRequest-class as stated in the XMLHttpRequest-specification.

I stumbled on to this when debugging 3rd party Javascript library which didn't work with HtmlUnit and it relied on xhr.response-attribute when handing Ajax responses.

Is there any workaround for this issue, for example, could I extend HtmlUnit's XMLHttpRequest-class and use it instead?

Thanks for any assistance.

Sorry there is not really a work around for this.
Will try to fix this soon - do you use the latest version?

[markoandersson]

Yes, version 2.53.0.

Thanks for the quick reply!

ok great, will have a look and come back to you (hopefully) soon.
Usually the implementation of that is not that hard (e.g. responseText is already here but writing detailed test for most of the cases takes some time.

Just made a new Snapshot build including a first impl for this. Please try and report your findings.

Works like a charm! Thank you for your fast response!

Btw. the third-party JS library is htmx and after this fix, at least all our (basic) use cases are covered and working with HtmlUnit.

With version 2.53.0 I got an error

2021-09-30 08:16:30.329 ERROR 91688 --- [           main] c.gargoylesoftware.htmlunit.WebConsole   : htmx:swapError

And with the snapshot version, our unit tests are passing.

Great. Thanks for the fast feedback and the report.

Have added initial support for contentType 'document'.
