I think he had a typo in his email. I believe he meant to write, I trayed:> document.myform.mymodel[''myfield''].value > document.myform.mymodel[myfield].value > document.myform.mymodel.myfield.value >The problem is that the form names have the []''s in them so you can''t just do document.myform.mymodel[myfield].value because javascript expects an array when it sees the []''s and it gets all confused.. I think this might work though: document.myform["mymodel[myfield]"].value not definitely sure, but it seems like it should. I never understood why Rails chose to use that notation on the field names. I think using dot noation wouldn''t been better .. like mymodel.myfield.. but what do I know.

Use the id of the form element:
(With prototype.js enabled:)
$(''mymodel_myfield'').value
