Focus on ajax newly-created form element

Rails
1

I have an ajax method that creates a new form. I want one of the
input boxes to be focused when the form gets displayed. So in my
inline RJS I have

page << “document.getElementById(‘post_title’).focus();”

The input box is being created with
<%= text_field ‘post’, ‘title’ %>, so the ID should end up being
‘post_title’ - FireFox’s DOM inspector confirms it.

However the text field isn’t getting focused, so I must be doing
something wrong. Any advice?

Give this a try:
page.send :record, “document.getElementById(‘post_title’).focus()”

Surely you can just use…

page[‘post_title’].focus
