如何在我当前的代码中插入先行功能(使用远程功能)?
的index.php:

// The percentage sign is a wild-card, in my example of countries it works like this...
// $queryString = 'Uni';
// Returned data = 'United States, United Kindom';
// YOU NEED TO ALTER THE QUERY TO MATCH YOUR DATABASE.
// eg: SELECT yourColumnName FROM yourTable WHERE yourColumnName LIKE '$queryString%' LIMIT 10
$query = $db->query("SELECT * FROM searchengine WHERE title LIKE '$queryString%' OR keywords LIKE '%" . $queryString . "%' OR link LIKE '%" . $queryString . "%' LIMIT 4");
if($query) {
// While there are results loop through them - fetching an Object (i like PHP5 btw!).
while ($result = $query ->fetch_object()) {
// Format the results, im using <li> for the list, you can change it.
// The onClick function fills the textbox with the result.
// YOU MUST CHANGE: $result->value to $result->your_colum
echo '<li onClick="fill(\''.$result->title.'\');">'.$result->title.'</li>';
}
} else {
echo 'ERROR: There was a problem with the query.';
}
} else {
// Dont do anything.
} // There is a queryString.

}
?>
我为typeahead函数编写了一些代码,但我不知道在哪里放置它,是否正确以及远程部分的代码。
先行草稿:

提前致谢。
