Question

我有选择和输入字段。输入中的值取决于选择值。当我选择选项中的选项并输入例如输入自动完成中的2时工作正常。当我更改所选值并在输入中输入相同的值时，例如等于2时出现问题。在这种情况下，自动完成功能不起作用。如果我键入不同于以前的值，一切都可以。有人可以帮助我吗？

getprojects

$results = $db->query('SELECT distinct PROJECT FROM Builds');
while ($row = $results->fetchArray())
    {
        $data[] = array(
        $row['PROJECT']
        );
    }   
echo json_encode($data); 
?>

getbuilds：

$db = new SQLite3('test.db');
$rs = $db->query("SELECT LABEL FROM Builds where PROJECT = '{$_REQUEST['q']}' 
    AND LABEL like '%{$_REQUEST['term']}%'");

$data = array();

while ($row = $rs->fetchArray())
    {
        $data[] = array(
            'label' => $row['LABEL']
        );
    }


echo json_encode($data);
flush();
?>

在输入字段中键入与上一个值相同的值时，没有自动完成操作
