Ruby on Rails: + AJAX: How do I set the value of a field

Question

there is

page.replace_html "id", thing to replace it with

but is there something where I can just insert a value into a text field?

Answer 1

I think you'll need to drop out of RJS and into Prototype for this one. For example, if your textfield id has a value "foo" then something like this might work:

page << %{
  var input = $('foo');

  input.writeAttribute('value', 'thing to replace it with');
}

updates the value attribute of the input element.

Answer 2

The way I found was to do this:

page[:object_column_name].value = whatever

its just the id of the field
