Prototype to jquery function

Question

I have a function for updating multiple selects based on values of another select.
How can I edit this function to use it without prototype just with jquery ?

function replace(val) {
 if (val != 0) {
 $$('select.replace).each(function(e) {
 var aa = e.value.split("_");
 if (aa[0] = val) {
 e.value = val + "_" + aa[1] + "_" + aa[2];
 jQuery("select.replace").trigger("chosen:updated");
 }
 });
 } else {
 alert('Please select a valid value');
 return false;
 }
}

Answer 1

It's simple:

jQuery( 'select.replace' ).each(function() {
 var aa = $( this ).val().split("_");
 if (aa[0] = val) {
 $( this ).val( val + "_" + aa[1] + "_" + aa[2] ); 
 //...

Try using .change() when the select value is changed.

$( ".target" ).change(function() {
 // code here
});
