</select>
I want is when I change dropdown1 to none the dropdown2 option will only show none and no other more.
And I also want is if I change the value of dropdown1 to an amount, for example 30000, dropdown2 will show only the values that are greater that 30000 including the option any.
Is there a way to do this in javascript or jQuery?
sorry. I'm new at javascript and jQuery.. Thank you in advance!

Reset to default 4Demo: http://jsfiddle/LsaLA/1/
Code:
function setTo() {
var f = $('#From').val();
var t = $('#To');
t.children().hide();
if( f == 'none' ) {
t.children('[value="none"]').show();
t.val('none');
}
else if( t == 'any' ) {
t.children().show();
t.val('any');
}
else {
f = parseInt(f, 10);
t.children().each(function() {
if( $(this).val() == 'any' ) {
$(this).show();
t.val('any');
}
else {
var v = parseInt($(this).val(), 10);
if(!isNaN(v) && v >= f) {
$(this).show();
}
}
});
t.val('any');
}
}
$('#From').change(setTo);
//call it on load as well
setTo();
try this: http://jsfiddle/F6xnL/4/
$("#From").change(function() {
$("#To").attr("disabled", false).children().each(function() {
$(this).attr('disabled', false);
});
if ($(this).val() === 'any') return;
if ($(this).val() === 'none') {
$("#To").val("none").attr("disabled", true);
return;
}
var pound = parseInt($(this).val());
$("#To").children().each(function() {
var val = $(this).val();
if (val === 'none' || val === 'any') {
$(this).attr('disabled', true); return;
}
if (parseInt($(this).val()) <= pound) {
$(this).attr('disabled', true);
}
});
});
$('#From').change(function(){
if($(this).val() == 'none'){
$('#To').prop('disabled', true);
}else if((true == $('#To').prop('disabled')) && ($(this).val() != 'none')){
$('#To').prop('disabled', false);
}
$('#To option').each(function(){
if($(this).val() < $('#From').val()){
$(this).hide(0);
}else{
if($(this).css('display') == 'none'){
$(this).show(0);
}
}
});
});
Untested, but this should work. I'm a bit verbose.
