Question

我当前的程序可以在包含字段名称的网页中打印所有表单，我也想打印当前值。

use WWW::Mechanize;
use LWP::UserAgent;
my $m = WWW::Mechanize->new();
$m->get("http://www.rediff.com/");
@arr   = $m->forms;
$count = 1;
foreach (@arr) {
    my @inputfields = $_->param;
    print "form $count fields are:\n";
    $count++;
    foreach (@inputfields) {
        print "$_\n";
    }
    print "\n";
}

输出：

form 1 fields are:
srchword
src

form 2 fields are:
login
passwd
remember
seclogin
FormName

预期：我想显示值，比如

login : abc@rediff.com

使用HTML::Form中记录的$form->value方法：

use strict;
use warnings;

use WWW::Mechanize;

my $m = WWW::Mechanize->new();
$m->get("http://www.rediff.com/");
my $count = 1;
for my $form ($m->forms) {
    print "form $count fields are:\n";
    $count++;
    for ($form->param) {
        printf "%s - %s\n", $_, $form->value($_);
    }
    print "\n";
}

输出：

form 1 fields are:
srchword - 
src - web

form 2 fields are:
login - 
passwd - 
remember - 1
seclogin - on
FormName - existing
