I want to get data to the dropdown by using another dropdown in the same page - laravel

Question

I have a dropdown on my page to load districts. And I have another dropdown to load Divisions according to that selected district. The below code I have got all the divisions. But I want only the divisions according to the selected districts. How can I do?
#php
$districtAll=\App\District::all();
#endphp
<div class="row">
<label class="col-md-4 control-label" for="district">9. District</label>
<div class="col-md-8">
<select name="district">
<option type="text" class="detail-wp" value="">Select District</option>
#foreach($districtAll as $all)
<option value="{{$all->DISTRICT_ID}}">{{$all->DISTRICT}} </option>
#endforeach
</select>
</div>
</div>
<br>
#php
$getDsAll=\App\DsDivision::all();
#endphp
<div class="row">
<label class="col-md-4 control-label" for="ds_division">10. DS Division</label>
<div class="col-md-8">
<select name="ds_division" class="form-control">
<option type="text" class="detail-wp" value=""></option>
#foreach($getDsAll as $all)
<option value="{{$all->DIVISION_ID}}">{{$all->DIVISION}} </option>
#endforeach
</select>
</div>
</div>

Answer 1

You can do it using ajax request:
$('select[name=district]').on('change', function(){
$districtId = $(this).val();
$.get('/division/district/'+$districtId).done(function(res){
$.each(res, function (key, value) {
$('select[name=ds_division]').append(`<option value='` + value.id + `'>` + value.name +`</option>`);
});
});
to make this working you will need a route like
Route::get("/division/district/{district}", "DivisionController#getByDistrictId");
DivisionController#getByDistrictIdwill be
public function getByDistrictId($district)
{
return Division::where('district_id',$district)->get();
}
this code just to give you an idea of how you can do it.
