collection_select :onchange event

Hello,

it´s simple,

i have an collection_select that work well and im trying to fire some
action in the controller passing the value that the user has selected.
obs: without ajax request...

Then create a script like this...

function JumpToIt(list){
    var selection = list.options[list.selectedIndex].value;
    location.href = "/controller/action/" + selection; // here
selection acts as params
}

where you have to call the function in onChange
.... :onChange => 'Jumpto(this);'

Regards.
