<option></option>
<option>California</option>
<option>New York</option>
<option>New Jersey</option>

Kumusta Edmhar,
The fiddle you have shown works fine. Just include this line in your <head> tags...
<script src="https://code.jquery.com/jquery-2.1.1.min.js" type="text/javascript"></script>
Happy Coding !

In order to easily achieve what you want, you can use jQuery which you can download here .
Then I added id tags for your <select> fields and value tags for your options.
<select class="form-control" name="country" id="country" required>
<option selected disabled>*Select Country </option>
<option option="USA">USA</option>
<option option="Philippines">Philippines</option>
<option option="Canada">Canada</option>
</select>
<select class="form-control" name="loc" id="loc" required>
<!-- REST OF OTHER CODES -->
Then create the script:
<script src="jquery-1.9.1.min.js"></script><!-- REPLACE NECESSARY JQUERY FILE DEPENDING ON THE VERSION YOU HAVE DOWNLOADED -->
<!-- START CREATING YOUR SCRIPT -->
<script type="text/javascript">
$(document).ready(function(){
$("#country").change(function(){
var country = $(this).val();
var usa = '<option>California</option><option>New York</option><option>New Jersey</option><option>Illinois</option><option>Others</option>';
var phi = '<option>Manila</option><option>Quezon City</option><option>Makati</option><option>Cebu</option><option>Davao</option><option>Others</option>';
var can = '<option>Toronto</option><option>Vancouver</option>';
var other = '<option selected disabled>*State / City</option>';
if(country == "USA"){
$("#loc").empty().append(usa);
}
else if(country == "Philippines"){
$("#loc").empty().append(phi);
}
else if(country == "Canada"){
$("#loc").empty().append(can);
}
else {
$("#loc").empty().append(other);
}
});
});
</script>
Take a look at this JSFiddle .
I have to scrap my first answer knowing that your form is a static one.
