OK, I solved #1. Indeed, the solution is trivial, but I had to trouble
this group in order to get to it - as always :(.
Here's the solution, in case anyone may find it helpful. It's a JS
defined using the model's js attribute. I'm not much of a JS coder, so
please don't hold the quality of this code against me :).
addEvent(window, 'load', hide_other); // Register a callback to when
the page has been loaded.
var other_index = 0; // Index of the option that triggers the other
field display
var type_field; // The field that triggers the display
var other_field; // The field that is displayed
function change_handler()
{
if (type_field.selectedIndex == other_index) {
other_field.parentNode.style.display = ''
} else {
other_field.parentNode.style.display = 'none'
}
}
function hide_other()
{
other_field = document.getElementById('id_other_workout_type');
div = other_field.parentNode;
div.style.display = 'none'
type_field = document.getElementById('id_workout_type');
for (i = 0; i < type_field.length; i++) {
if (type_field.options[i].text == 'Other') {
other_index = i;
}
}
if (type_field.addEventListener) {
type_field.addEventListener("change", change_handler, false);
} else if (type_field.attachEvent) {
type_field.attachEvent("onchange", change_handler);
} else {
type_field.onchange = change_handler;
}
}
