php+mysql+ajax實(shí)現(xiàn)百度搜索下拉提示框主要有3個(gè)文件三個(gè)文件在同一個(gè)目錄里如下圖下面是三個(gè)文件的代碼把sql文件導(dǎo)入到mysql數(shù)據(jù)庫(kù)里修改下數(shù)據(jù)庫(kù)密碼為自己的記得哦是UTF-8編碼

下面是三個(gè)文件的代碼把sql文件導(dǎo)入到mysql數(shù)據(jù)庫(kù)里修改下數(shù)據(jù)庫(kù)密碼為自己的記得哦是UTF-8編碼

效果圖

rpc.php文件

復(fù)制代碼代碼如下:

 
<?php 
mysql_connect('localhost', 'root' ,''); 
mysql_select_db("test"); 
$queryString = $_POST['queryString']; 
if(strlen($queryString) >0) { 
$sql= "SELECT value FROM countries WHERE value LIKE '".$queryString."%' LIMIT 10"; 
$query = mysql_query($sql); 
while ($result = mysql_fetch_array($query,MYSQL_BOTH)){ 
$value=$result['value']; 
echo '<li onClick="fill(\''.$value.'\');">'.$value.'</li>'; 
} 
} 
?> 

index.htm文件

復(fù)制代碼代碼如下:
