I’m still a beginner with RJS so forgive me if this is a simple one -
but certainly it doesn’t seem logical and googling has not led to .
Given a field with an id of ‘posting_subject’ I can do the following in
my controller with RJS.
render :update do | page |
subject = 'this is really something
page['posting_subject'].value = subject
end
And we sing and rejoice. But why can’t I do
render :update do | page |
page['comment_subject'].value = page['posting_subject'].value
end
At the Javascript level the error is that we get
${'posting_subject'}.value()
instead of
${'posting_subject'}.value
And value is not a function. So, how can I get a value of a form
element!?
