PHP和JavaScript交互的例子,摘自http://www.w3schools.com/php/php_ajax_php.asp<html> <head> <script type="text/javascript"> function showHint(str) { if (str.length==0) { document.getElementById("txtHint").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","gethint.php?q="+str,true); xmlhttp.send(); } </script> </head <body><p><b>Start typing a name in the input field below:</b></p> <form> First name: <input type="text" onkeyup="showHint(this.value)" size="20" /> </form> <p>Suggestions: <span id="txtHint"></span></p></body> </html>
下面的是gethint.php文件 <?php // Fill up array with names $a[]="Anna"; $a[]="Brittany"; $a[]="Cinderella"; $a[]="Diana"; $a[]="Eva"; $a[]="Fiona"; $a[]="Gunda"; $a[]="Hege"; $a[]="Inga"; $a[]="Johanna"; $a[]="Kitty"; $a[]="Linda"; $a[]="Nina"; $a[]="Ophelia"; $a[]="Petunia"; $a[]="Amanda"; $a[]="Raquel"; $a[]="Cindy"; $a[]="Doris"; $a[]="Eve"; $a[]="Evita"; $a[]="Sunniva"; $a[]="Tove"; $a[]="Unni"; $a[]="Violet"; $a[]="Liza"; $a[]="Elizabeth"; $a[]="Ellen"; $a[]="Wenche"; $a[]="Vicky";//get the q parameter from URL $q=$_GET["q"];//lookup all hints from array if length of q>0 if (strlen($q) > 0) { $hint=""; for($i=0; $i<count($a); $i++) { if (strtolower($q)==strtolower(substr($a[$i],0,strlen($q)))) { if ($hint=="") { $hint=$a[$i]; } else { $hint=$hint." , ".$a[$i]; } } } }// Set output to "no suggestion" if no hint were found // or to the correct values if ($hint == "") { $response="no suggestion"; } else { $response=$hint; }//output the response echo $response; ?>
2 也可以做个中间页面 先迁移到中间页面 在中页面+1 +完之后跳转到你要去的页面
可不可以 再详细点啊
我的超链接 已经在循环里了while ($row=mysql_fetch_row($result))
{
?>
<li><a href="inside.php?ctid=<?php echo $row[0];?>"><?php echo mb_substr($row[2],0,15,'utf-8'); ?></a></li>
<?php
}
// 释放资源
mysql_free_result($result);
// 关闭连接
//mysql_close();
有没有源码 参考参考啊
谢谢。
