【问题描述】：
使用 Jquery Autocomplete，如果您输入几个字母（您可以使用“Shawn”、“Vinnie”、“Lisa”）名称下拉列表，您可以选择一个。当你这样做时，它会在下面的文本框中抛出名称。但是，如果您选择了一个名称并选择了它，发现它是错误的名称并从文本框中手动删除它，这似乎破坏了功能（即，如果您尝试再次选择一个名称，您可以，但它会不会出现在文本框中）。
有什么明显的我做错了吗？
另外，附注，有没有办法只允许在文本框中输入一个名字，因为应该总是只有一个主管？
这里是完整的代码：
<?php
session_start();
require_once('includes/databaseconfig.php');
//Get employees to put in the availablePlayers array for autocomplete
$sql = "SELECT * FROM users
ORDER BY lname";
$allemployees = mysqli_query($con, $sql);
if (!$allemployees) {
die("Database query failed: " . mysqli_error($con));
} else {
while ($row = mysqli_fetch_assoc($allemployees)) {
$supervisordata .= "{ value: \"" . $row['fname'] . " " . $row['lname'] . " \",
label: \"" . $row['fname'] . " " . $row['lname'] . "\",
icon: \"<img src='" . $row['picture'] . "'>\"},";
}
}
?>
