Jquery to change dropdown value of 2nd dropdown on chnage of first.

So this is a very simple code.
Essentially we can use this logic for other html elements as well. Since I encountered such a situation. Posting this for the dropdown element.
   wmdropdown_countrycode:- id of dropdown 1
    wmdropdown_nationality:- id of dropdown 2

myfunction() {

$(

'#wmdropdown_countrycode').change(function(){ var selectedCountry = $(this).attr('value');

$(

'#wmdropdown_nationality').find('option').each(function() { if($(this).val().toLowerCase() == selectedCountry.toLowerCase()){

$(

this).attr('selected','selected');

}

});

});

}
