Visualizaçõesdata showing in single option instead of multiple option from json array
I have a JSON array in a JSON file looks like this:
{
"states": [
{
"state": "Andhra Pradesh",
"districts": [
"Anantapur",
"Chittoor",
"East Godavari",
"Guntur",
"Krishna",
"Kurnool",
"Nellore",
"Prakasam",
"Srikakulam",
"Visakhapatnam",
"Vizianagaram",
"West Godavari",
"YSR Kadapa"]
}
]
}
and I am successfully able to load all states in the select element as a dependent select option . when I select a state from a select element it populates a related array in the district select element. but instead of the array showing a separate option it shows as one option:
Should I modify my JSON array in a different format?
jquery
$('#statePicker').on('change', function() {
$("#cityPicker").html('');
$.ajax({
url: "{{ asset('json/in-sc-list.json') }}",
type: "GET",
dataType: 'json',
success: function(res) {
$('#cityPicker').html('<option value="">Select City</option>');
$.each(res.states, function(key, value) {
if (value.state == $('#statePicker').val()) {
console.log(value.districts);
$("#cityPicker").append('<option value="' + value
.districts + '">' + value.districts + '</option>');
}
});
}
});
});
blade
<span>
<select id="statePicker" name="statePicker" required class="form-control"></select>
<select id="cityPicker" name="cityPicker" required class="form-control"></select>
</span>

let statePicker = $('#statePicker').val();
let list = $("#cityPicker");
$.each(res.states, function(key, value) {
if (value.state == statePicker) {
$.each(items, function(item) {
list.append(new Option(item, item));
});
}
});
You need to loop value.districts because its an array, and also, you are doing it in a dirty way, you are initializing $("#cityPicker") on every loop, This might give some performance issues in future if the list items increases.

Your data structure is fine. The issue is that you're not creating multiple option elements, you're only creating one. This part is off:
$("#cityPicker").append('<option value="' + value
.districts + '">' + value.districts + '</option>');
}
What you want to do is create an option element for each district, as follows:
for (const district of value.districts) {
$("#cityPicker").append('<option value="' + district + '">' + district + '</option>');
}
