Hi,
I had a previous question that touched this topic (http://stackoverflow.com/questions/1131694/rails-how-to-get-value-from-another-field-when-executing-an-onchange-remote-func), but then I dugg a little deeper and realized that my problem is the datetime_select method.
I have a textfield with onchange. In the onchange I need to get the value of a datetime_select field to pass as a parameter when making the ajax call to my controller. The first thing to note is that a datetime_select is actually composed of five dropdowns (year, month, day, hour and minute), so I need to get the values of each of them separately (I presume, is there a simpler way?). But when I try to get their value with code like:
$(model + '_' + attribute + '_3i').value
which should return the value of the "day" dropdown I get an error: "TypeError: $("model_attribute_3i").value.toS is not a function"
If I create all the dropdowns for the datetime objects manually the same call works just fine. So there seems to be some magic in the way a datetime_select is composed that prevents me from asking the value of the dropdowns. Is there any way to go around this or do I just have to recode the datetime_select functionality in my application?
