Scott,

I am sorry to say that I do not have a great answer for you. We also have not been able to find an IDE that handles code-completion well for javascript. Most of the LabKey developers use the Ultimate edition of IntelliJ (which has code completion support for javascript) for javascript development, but IntelliJ code completion for javascript also has problems (ie not working for all functions). Thus most do use the IDE's code completion, but instead use the javascript API reference documentation located at https://www.labkey.org/download/clientapi_docs/javascript-api/


NOTE: As you found out the community edition of IntelliJ does not support code completion for javascript.

Again, sorry that I do not have any better advice.
