Hi I'm trying to figure out how to fill all fields using ajax call, it successfully doing by selecting category, it loads all related sub_categories.
But sub_sub_category
fields are empty. Only when I choose sub_category
option it will load all sub_sub_categories
, but I want all prefilled once category has been changed. I don't mind to leave like this, but problem is if I have only single sub_category
I can not select any sub_sub_category
even if they have any I tried to convert to function and call them but no success.
Code below:
<script>
$(document).ready(function() {
get_sub_sub_category();
$('select[name="category_id"]').on('change', function() {
var category_id = $(this).val();
if(category_id) {
$.ajax({
url: "{{ url('/category/sub-category/') }}/" category_id,
type: "GET",
dataType: "json",
success: function(data) {
$('select[name="sub_sub_category_id"]').html('');
var d = $('select[name="sub_category_id"]').empty();
$.each(data, function(key, value) {
$('select[name="sub_category_id"]').append('<option value="' value.id '">' value.sub_category_name '</option>');
});
get_sub_sub_category();
},
})
} else {
alert('danger');
}
});
function get_sub_sub_category() {
$('select[name="sub_category_id"]').on('load change', function () {
var sub_category_id = $(this).val();
if (sub_category_id) {
$.ajax({
url: "{{ url('/category/sub-sub-category/') }}/" sub_category_id,
type: "GET",
dataType: "json",
success: function (data) {
var d = $('select[name="sub_sub_category_id"]').empty();
$.each(data, function (key, value) {
$('select[name="sub_sub_category_id"]').append('<option value="' value.id '">' value.sub_sub_category_name '</option>');
});
},
})
} else {
alert('danger');
}
});
}
});
</script>

You might want to consider the following.
$(function() {
$('select[name="category_id"]').on('change', function() {
var category_id = $(this).val();
if (category_id) {
$.ajax({
url: "{{ url('/category/sub-category/') }}/" category_id,
type: "GET",
dataType: "json",
success: function(data) {
$('select[name="sub_sub_category_id"]').html('');
var d = $('select[name="sub_category_id"]').empty();
$.each(data, function(key, value) {
$('select[name="sub_category_id"]').append('<option value="' value.id '">' value.sub_category_name '</option>');
});
$('select[name="sub_category_id"]').trigger("change");
},
})
} else {
alert('danger');
}
});
$('select[name="sub_category_id"]').on('change', function() {
var sub_category_id = $(this).val();
if (sub_category_id) {
$.ajax({
url: "{{ url('/category/sub-sub-category/') }}/" sub_category_id,
type: "GET",
dataType: "json",
success: function(data) {
var d = $('select[name="sub_sub_category_id"]').empty();
$.each(data, function(key, value) {
$('select[name="sub_sub_category_id"]').append('<option value="' value.id '">' value.sub_sub_category_name '</option>');
});
},
})
} else {
alert('danger');
}
});
});
This defined the callbacks for both. For category, when it is changed, it triggers change
event on sub-category. This in turn will cascade the loading of the next Select.
