sl_getGroups is being called. i printed out alerts when i was writing
it. and i have Sys.outs in the action. besides, my JSP wouldn't show
up if it wasn't :)
the javascript is fairly simple: (i know there is a more Strutsy way
to do this, i'm getting there...)
function sl_getGroups(frm) {
if (frm.selectedShoppingList.options[frm.selectedShoppingList.selectedIndex].value
!= "-1") {
frm.selectedShoppingList.options[frm.selectedShoppingList.selectedIndex].value
= "-1";
frm.action += "?step=getGroups";
frm.submit();
}
}
the javascript just checks to see that the selectedShoppingList is not
"-1", the initial value. it then appends my step parameter to the
action. this is working. what is funny is that the javascript
recognizes that the selectedShoppingList is not "-1", but the form
doesn't pick that up...
any suggestions?
