cgi的start_html()方法可以有多个-script属性吗？

Question

我认为这个问题非常自我解释,但我使用perl来生成一个网页.开始使用:

$cgi->start_html(-title=>'myPage',-style=>{-src=>'style.css'},  -script=>{-type=>'JAVASCRIPT', -src=>'custom.js'}, );

项目清单

但是如果我想在标题中有多个脚本呢？还是多个CSS样式表？

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script type="text/javascript" src="custom.js"></script>
<link rel="stylesheet" href="css/basic.css" type="text/css" />
<link rel="stylesheet" href="css/style.css" type="text/css" />

Answer 1

使用匿名数组：

$cgi->start_html(
  -title=>'myPage',
  -style=>[{-src=>'style.css'},{-src=>'basic.css'}],
  -script=>[{-type=>'JAVASCRIPT', -src=>'custom.js'},{-type=>'JAVASCRIPT', -src=>'http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js'}],
);

Answer 2

当然。当您想到多个时，请考虑数组。当您考虑将数组作为参数传递时，请考虑数组 ref。
