There is no such thing as an AJAX server.
在AJAX服务器端并没有什么特别的东西
AJAX pages can be served by any internet server.
任何网络服务器都可以提供AJAX页面服务
AJAX 服务端页面 - ASP 和 PHP
The server page called by the JavaScript in the example from the previous chapters is a simple ASP file called "gethint.asp".
上一篇中被JS所调用的服务端ASP页面的名称为"gethint.asp"
Below we have listed two examples of the server page code, one written in ASP and one in PHP.
下面我们会举出两个例子,一个是用ASP写的,另一个是用PHP写的。
AJAX ASP 举例
The code in the "gethint.asp" page is written in VBScript for an Internet Information Server (IIS). It just checks an array of names and returns the corresponding names to the client:
在 "gethint.asp"里所写的代码是用了VBScript,可以运行在IIS上。它只是对数组的名称做了检查并将合适的名称反馈给了客户端:
<% dim a(30) 'Fill up array with names a(1)="Anna" a(2)="Brittany"
a(3)="Cinderella" a(4)="Diana" a(5)="Eva" a(6)="Fiona" a(7)="Gunda" a(8)="Hege"
a(9)="Inga" a(10)="Johanna" a(11)="Kitty" a(12)="Linda" a(13)="Nina" a(14)="Ophelia"
a(15)="Petunia" a(16)="Amanda" a(17)="Raquel" a(18)="Cindy" a(19)="Doris" a(20)="Eve"
a(21)="Evita" a(22)="Sunniva" a(23)="Tove" a(24)="Unni" a(25)="Violet" a(26)="Liza"
a(27)="Elizabeth" a(28)="Ellen" a(29)="Wenche" a(30)="Vicky" 'get the q parameter from URL q=ucase(request.querystring("q")) 'lookup all hints from array if length of q>0 if len(q)>0 then hint=""
for i=1 to 30 if q=ucase(mid(a(i),1,len(q))) then if hint="" then hint=a(i) else hint=hint & " , " & a(i) end if end if next end if 'Output "no suggestion" if no hint where found 'or output the correct values if hint="" then response.write("no suggestion") else response.write(hint) end if %> |
AJAX PHP 举例
The code above rewritten in PHP.
将上面的代码用php来写出
Note: To run the entire example in PHP, remember to change the value of the url variable in "clienthint.js" from "gethint.asp" to "gethint.php".
注意:如果要运行PHP,请记得要把"clienthint.js"中url变量值从"gethint.asp" 改成 "gethint.php"
PHP 举例
<?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 where found // or to the correct values if ($hint == "") { $response="no suggestion"; } else { $response=$hint; }
//output the response echo $response; ?> |
