Question

我从9lessons.info获得了这个脚本，当你输入@符号时它应该自动建议朋友。

问题是从数据库获取名称后，光标指向文本区域的开头。我想专注于输入文本字段，以便将光标放在文本的末尾。

源代码：

PHP代码

<?php
include('config.php');

if($_POST){
    $q=$_POST['searchword'];
    $q=str_replace("@","",$q);
    $q=str_replace(" ","%",$q);
    $sql_res=mysql_query("select * from user_data where fname like '%$q%' or lname like '%$q%' order by id LIMIT 5");
    while($row=mysql_fetch_array($sql_res)){
        $fname=$row['fname'];
        $lname=$row['lname'];
        $img=$row['img'];
        $country=$row['country'];

    ?>
    <div class="display_box" align="left">
    <!--<img src="user_img/<?php echo $img; ?>" class="image"/>-->
    <a href="#" class='addname' title='<?php echo $fname; ?>&nbsp;<?php echo $lname; ?>'>
    <?php echo $fname; ?>&nbsp;<?php echo $lname; ?> </a><br/></div>
    <?php
    }
}
?>
