I have got two forms, the first is a textarea plus a link that activates
some javascript to change the form, the second activates some javascript
on the onchange event which changes it into a textarea form.
This works in Firefox, but not in Safari.
Also, I need the value which is selected. I’ve found an example that
gives the parameter to the javascript, like this:
How do I get the value which is selected when the onchange event occurs
using RJS?
Thanks,
