I have ts code to use with jquery autoplete
Here is code
function load_autoplete_fields(){
$('.airport_field').each(function() {
$(this).autoplete({
delay:10,
minLength: 0,
source(request, response) {
$(this.element[0]).attr('data-req-term', request.term);
$.ajax({
url: $(this.element[0]).attr('data-source'),
dataType: "json",
data: {
term: request.term
},
success(data) {
const results = [];
$.map(data.cities, function(value, key) {
results.push(value);
return $.map(value.airports, (value2, key2) => results.push(value2));
});
$.map(data.airports, (value, key) => results.push(value));
return response(results);},
error() { return response([]); }
});
return null;},
focus(event, ui) {
return false;},
select(event, ui) {
const qel = $(event.currentTarget);
qel.val(ui.item.fullname);
$(qel.attr('data-id-element')).val(ui.item.id);
return false;}
}).data("ui-autoplete")._renderItem = function(ul, item) {
return create_autoplete_item($(this.element[0]), ul, item);
};
$('.airport_field').on('autopleteselect', function() {
if (this.id.indexOf('origin') !== -1) {
const id = this.id.split('_')[2];
return $(`#search_legs_${id}_destination_text`).focus();
}
});
return $('.airport_field').focus(function() {
if (!$(this).val()) { return $(this).val(' ').keydown(); }
});
});
}
When I try to pile it I have this error
Argument of type '() => JQuery' is not assignable to parameter of type '(this: HTMLElement, index: number, element: HTMLElement) => false | void'. Type 'JQuery' is not assignable to type 'false | void'. Type 'JQuery' is not assignable to type 'void'.
in this row $('.airport_field').each(function() {
Here is HTML
<ul>
<li>
<div class="header"><%= _('Från') %></div>
<%= text_field_tag 'search[legs][0][origin_text]', @default_lsp[:legs][0][:origin_city][:return],

Reset to default 3In this line:
return $('.airport_field').focus(function () {
if (!$(this).val()) { return $(this).val(' ').keydown(); }
});
Why are you returning the result of that call? The each() method doesn't want you to return anything unless you want to stop the iteration early, in which case you should return false. That's what the error is telling you:
Argument of type '() => JQuery' is not assignable to parameter of type '(this: HTMLElement, index: number, element: HTMLElement) => false | void'. Type 'JQuery' is not assignable to type 'false | void'. Type 'JQuery' is not assignable to type 'void'.
means
The function is returning a
JQuery, which isn't appropriate. It should returnfalseorvoid, andJQueryisn't either one of those. Specifically, it's notvoid.
Maybe you should change the above line to just
$('.airport_field').focus(function () {
if (!$(this).val()) { return $(this).val(' ').keydown(); }
});
without the return and see if it works.
Hope that helps. Good luck.
