I need to create a select In this pattern:
<select id="Cidades">
<option></option>
</select>
Where the user will select its state, and then a jquery will be made that searches the cities according to the selected state. so far I can do (but not yet done), my problem is how would I send the return data of json to the dropdown (Select), and I wanted to know if the select the above is also correct to fill in the data.

$.ajax({
type: ...,
url: ...,
datatype: "Json",
data: { ... },
success: function (data) {
if (data.length > 0) {
$.each(data, function (index, value) {
$('#Cidades').append('<option value="' + value.Id+ '">' + value.Nome + '</option>');
});
} else {
var novaOpcao = $('<option value=""></option>');
$('#Cidades').append(newOption);
}
}
});
The return enters the callback Success. It uses a loop for each city returned in Json. I put as value. id and value. Name to reference the properties of the City entity, but if it is another just adjust.
"Else" forces a null option if there are no cities registered for that state, hence it facilitates validation at least of the front end if you have defined this.
It worked, but if I click more than once on the button, it fills in the data by duplicating everything. I believe I would have to clear this list first, before adding again. You know how I can do?
