这个程序是利用php+ajax+jquery 实现的一个仿baidu智能提示的效果,有需要的朋友可以下载测试,代码如下:

index.html文件,保保存成index.htm,代码如下:

<!DOCTYPE html>

  function lookup(inputString) {
    if (inputString.length == 0) {
        // Hide the suggestion box.
        $(&#39;#suggestions&#39;).hide();
    } else {
        $.post("rpc.php", {
            queryString : "" + inputString + ""
        }, function (data) {
            if (data.length > 0) {
                $(&#39;#suggestions&#39;).show();
                $(&#39;#autoSuggestionsList&#39;).html(data);
            }
        });
    }
 } // lookup
 function fill(thisValue) {
    $(&#39;#inputString&#39;).val(thisValue);
    setTimeout("$(&#39;#suggestions&#39;).hide();", 200);
 }
</script>

    </div> 
   </div> 
  </form> 
 </div> 
</body> 
</html> 
php文件,代码如下:
<?php 
    mysql_connect(&#39;localhost&#39;, &#39;root&#39; ,&#39;root&#39;); 
 mysql_select_db("autoComplete");  
 $queryString = $_POST[&#39;queryString&#39;]; 
   //开源代码phprm.com 
   if(strlen($queryString) >0) { 
    $sql= "SELECT value FROM countries WHERE value LIKE &#39;".$queryString."%&#39; LIMIT 10"; 
    $query = mysql_query($sql); 
    while ($result = mysql_fetch_array($query,MYSQL_BOTH)){      
     $value=$result[&#39;value&#39;]; 
     echo &#39;<li onClick="fill(&#39;&#39;.$value.&#39;&#39;);">&#39;.$value.&#39;</li>&#39;; 
    } 
   }
?>

sql.sql把这里复制保存到你的数据库,代码如下:
