The "form_for" helper and its friends "text_field_for" etc generate form fields with names like "forum[title]", i.e. using square brackets to denote attributes on model objects.
Now, for the convenience of the user I want to do some simple client-side validation to check that some fields have been filled in. So I am trying to write javascript like
"if (myForm.forum[title].value == '') { return false; }",
myForm.elements['forum[title]'].value
