我有存储在Perl数组中的数据。如何使用JSON将它们转换为JavaScript数组？ [英] I have data stored in Perl array. How do I convert them into JavaScript array using JSON?

问题描述

下面是我想要做的一个类似的例子：

  @name = qw（Sam Tom John Mike Andrea ）; 
 @scores = qw（92 80 59 83 88）; 
  

我需要将这些数组存储为JavaScript，以便我可以在网页上制作有用的图表。假设你想保留它们作为单独的数组，首先将它们引用到哈希中：

解析方案

  my％data =（names => \ @ names，scores => \ @ scores）; 
  

然后使用 JSON 模块将数据结构序列化为JSON，例如：

  use strict; 
使用警告; 
 
使用JSON; 
 
 my @names = qw（Sam Tom John Mike Andrea）; 
 my @scores = qw（92 80 59 83 88）; 
 
 my％data =（names => \ @ names，scores => \ @ scores）; 
 
 my $ json = encode_json \％data; 
 $ b $ print $ json 
  

输出：

  {names：[Sam，Tom，John，Mike，Andrea]，scores：[92 ，80，59，83，88]} 
  

Here is a similar example of what I am trying to do:

@name = qw (Sam Tom John Mike Andrea);
@scores = qw (92 80 59 83 88);

I need to store these array as JavaScript so I can make useful graphs on the web page.

解决方案

Assuming you want to keep them as separate arrays, stick references to them in a hash first:

my %data = ( names => \@names, scores => \@scores );

Then use the JSON module to serialize the data structure to JSON, e.g.:

use strict;
use warnings;

use JSON;

my @names  = qw (Sam Tom John Mike Andrea);
my @scores = qw (92 80 59 83 88);

my %data = ( names => \@names, scores => \@scores );

my $json = encode_json \%data;

print $json

Output:

{"names":["Sam","Tom","John","Mike","Andrea"],"scores":["92","80","59","83","88"]}
