Recently, as I’ve gotten back into doing JS/DOM development, I’ve begun wishing more and more for a real JavaScript IDE. Mozilla is partway there (Jesse’s bookmarks, the DOM Inspector, and Venkmann are great), there still some stuff that I’d really like:

  • Object Browser – integrated with run-time watches/reflection, and with a comprehensive reference
  • Library management – integrated w/ Object Browser
  • BrowserCaps – flagging (a la TopStyle w/ CSS), cross-referenced w/ alternatives, bug-DB; inline auto-complete stuff would be neato

Is anyone still working on a ‘developer edition’ of Mozilla?

Hmm… it seems that when creating an image, Mozilla doesn’t update the height after changing the source, but after a reload it does. This is strange. I could just replace the offset subtractions with the static dimensions, but hopefully I can also find out what the proper behavior is supposed to be (or if it’s even specified).

The specs are unclear on the behavior of this, so I switched to the older DOM constructor so I could pre-declare width/height there. This incidentally breaks Safari corner rendering (assigning document.createElement(“img”).style properties work, but the JS engine just stops on Image.style properties – the Image object doesn’t inherit from the DOM2 Element object?)
