问题描述
我要打电话给我的输入域的模糊功能的Perl脚本。但我真的不知道如何做到这一点,我找不到任何工作的事情与谷歌。我的$ C $的HTML页中c为

这是我的Perl脚本,我认为这将是最简单的打印结果:/
#!的/ usr / bin中/ perl的
要求cgi-lib.pl;
使用funktionen;
使用的Getopt ::龙;
&安培; GetOptions(cardnumber:秒=> \ $ cardnumber);
$ cardnumber = $查询 - >参数('cardnumber');
如果($ cardnumber!=){
打印和放大器; funktionen :: checkbalance($ cardnumber);
}
您似乎已经通过在shell中运行它,用户编写的命令行脚本,设计为与互动。 (使用的Getopt是一个很大的线索在这里)。
为了拥有它你需要重写一遍,这样它会与网络服务器(而不是一个shell)的HTTP请求进行响应。
有几种方法可以做到这一点。一个简单的方法是使用CGI。现代的做法是使用普拉克,可能与一个框架相结合。
一个基本的介绍使用Perl / CGI和Apache在 Apache文档可用。你应该看看一个模块,如 CGI 为了处理输入数据,并正确地发出HTTP标头。
您可以了解更多有关普拉克从项目的主页,其中包括链接到一些框架使用它
I want to call an Perl script in the blur function of my input field. But i dont really know how to do this, and i cant find any working things with google. my code of the html page is

success: function(msg){
alert(msg);

<!-- <div class="haupt"> -->

This is my Perl script, i thought it will be the easiest to print the result :/.
#!/usr/bin/perl
require "cgi-lib.pl";
use funktionen;
use Getopt::Long;
&GetOptions("cardnumber:s" =>\$cardnumber);
$cardnumber=$query->param('cardnumber');
if ($cardnumber != "") {
print &funktionen::checkbalance($cardnumber);
}
You appear to have written a command line script, designed to be interacted with by a user running it in a shell. (The use of Getopt is a big clue here).
In order to have it respond to an HTTP request you need to rewrite it so that it will work with a webserver (instead of a shell).
There are several ways to do this. A simple approach would be to use CGI. A modern approach would be to use Plack, possibly in conjunction with a framework.
A basic introduction to using Perl/CGI with Apache is available in the Apache documentation. You should look at a module such as CGI in order to process incoming data and emit HTTP headers correctly.
You can find out more about Plack from the project's homepage, which includes links to a number of frameworks that use it.
