我正在执行自动完成功能并且我传递参数，但它不起作用。
$("#destination-region").autocomplete({
source: "/interface/regions_datalist.php?idCountry="+$("#destination-country-id").val(),
minLength: 2,
select:
function (event, ui) {
$("#destination-region-id").val(ui.item.idRegion);
$("#destination-country-preview")
.html('<i class="fa fa-map-pin" aria-hidden="true"></i> ' + $("#destination-country").val() + " - " + $("#destination-region").val());
}
});
这是我的PHP代码（我已尝试使用此链接：www.site.ext / interface / regions_datalist.php？idCountry = 1＆amp; term = la）并且它有效！
<?php
include_once "../core/adminAutoloader.php";
$idCountry = $_GET["idCountry"];
$name = $_GET["term"];
$regionFacade = new regionFacade();
$regions = $regionFacade->findRegionByNameAndCountry($idCountry,$name);
$regionsArray = array();
while($region = $regions->fetch(PDO::FETCH_ASSOC)) {
$tmpRegion["idRegion"] = $region["idRegion"];
$tmpRegion["value"] = $region["name"];
$tmpRegion["label"] = $region["name"];
array_push($regionsArray,$tmpRegion);
}
echo json_encode($regionsArray);
