The modern complement Vim plugin for JavaScript guys.

Set jscomplete#CompleteJS to omnifunc in your .vimrc like this.

autocmd FileType javascript
  \ :setl omnifunc=jscomplete#CompleteJS

Then available complement properties after .,[ keywords.

neocomplcache is the Vim plugin to keyword completion. No more is necessary to basically using.

Extension scripts under the autoload/js/ will be loaded with set list to g:jscomplete_use or b:jscomplete_use in your .vimrc like this.

:let g:jscomplete_use = ['dom', 'moz']

• dom.vim : Adding DOM keywords completion.
• moz.vim : Adding Mozilla JavaScript keywords completion.
• xpcom.vim : Adding Mozilla XPCOM component keywords completion.
