我想将表格中的单元格值与其标题相关联。标题是未知的,因为它是 由SQL查询生成。
标题大小来自SQL返回结果。然后把它放到一个数组中,
@sizes = qw(S36 S37 S38 S39 S40 S41 S42);
现在,如果詹姆斯的身高是S38。
我想将它们打印为带有尺寸标题的HTML表格:
+--------+--------+--------+-------+-------+-------+-------+
| S36 | S37 | S38 | S39 | S40 | S41 | S42 |
+--------+--------+--------+-------+-------+-------+-------+
| | | James | | | | |
+--------+--------+--------+-------+-------+-------+-------+
我知道如果大小是行或结果的一部分,但是作为表头?
,如何执行此操作如何用Perl操纵它?
编辑:
我试着总结一下我试过的代码......
SQL查询:
select size from articles where order_number = "3";
进入阵列:
while(my $ref = $sth->fetchrow_hashref()) {
$size = "$ref->{'size'}";
push @sizes, $size;
}
说,@sizes
是:
@sizes = qw(S36 S37 S38 S39 S40 S41 S42);
根据尺寸创建HTML标头:
+--------+--------+--------+-------+-------+-------+-------+
| S36 | S37 | S38 | S39 | S40 | S41 | S42 |
+--------+--------+--------+-------+-------+-------+-------+
现在,从另一个SQL查询说,我知道詹姆斯有S38。 如何放入上表的右侧行单元格。它将是:
+--------+--------+--------+-------+-------+-------+-------+
| S36 | S37 | S38 | S39 | S40 | S41 | S42 |
+--------+--------+--------+-------+-------+-------+-------+
| | | James | | | | |
+--------+--------+--------+-------+-------+-------+-------+

以下是使用CGI.pm HTML生成方法执行此操作的方法:
#!/usr/bin/perl
use strict;
use warnings;
use CGI qw(:html);
use List::AllUtils qw( first_index );
my @sizes = qw(S36 S37 S38 S39 S40 S41 S42);
my %person = ( name => 'James', size => 'S38');
my @row = ('') x @sizes;
$row[ first_index { $_ eq $person{size} } @sizes ] = $person{name};
print start_html,
table( { border => 1 },
Tr(td({width => sprintf('%.0f%%', 100/@sizes)}, \@sizes)),
Tr(td(\@row) ) ),
end_html;
另一方面,我很喜欢HTML::Template:
#!/usr/bin/perl
use strict; use warnings;
use HTML::Template;
use List::AllUtils qw( first_index );
my @sizes = qw(S36 S37 S38 S39 S40 S41 S42);
my %person = ( name => 'James', size => 'S38');
my @row = (' ') x @sizes;
$row[ first_index { $_ eq $person{size} } @sizes ] = $person{name};
my $tmpl_txt = <<EO_TMPL;
<html><head><style type="text/css">
#size_chart { margin: 0 auto; }
#size_chart td { width: <TMPL_VAR CELL_WIDTH>; border: 2px inset #ddd }
</style></head>
<body><table id="size_chart">
<TMPL_LOOP ROWS><tr>
<TMPL_LOOP CELLS><td><TMPL_VAR CELL></td></TMPL_LOOP>
</tr></TMPL_LOOP>
</table></body></html>
EO_TMPL
my $tmpl = HTML::Template->new(scalarref => \$tmpl_txt);
$tmpl->param(
CELL_WIDTH => sprintf('%.0f%%', 100/@sizes),
ROWS => [ { CELLS => [ map { { CELL => $_ } } @sizes ] },
{ CELLS => [ map { { CELL => $_ } } @row ] },
]);
print $tmpl->output;
