如何将自定义代码添加到标题中

Question

如何将以下行添加到组件的标题中?

<!--[if lt IE 9]><script language="javascript" type="text/javascript" src="js/excanvas.min.js"></script><![endif]-->

Answer 1

不确定它是否适用于任何文本，但您可以尝试:

$document =& JFactory::getDocument();
$document->addCustomTag('<!--[if lt IE 9]><script language="javascript" type="text/javascript" src="js/excanvas.min.js"></script><![endif]-->');

Answer 2

您可以使用:

<?php
    $document = &JFactory::getDocument();
    $document->addScript( '/js/excanvas.min.js' );
?>

我正在寻找如何添加条件语句虽然…

检查用户代理是否为IE

<?php
    $document = &JFactory::getDocument();
    //Is it Internet Explorer?
    ereg('MSIE ([0-9].[0-9])',$_SERVER['HTTP_USER_AGENT'],$reg);
    if(isset($reg[1])) {
        //Yes, it is Internet Explorer
        $document->addScript( '/js/excanvas.min.js' );
    }
?>
