如何将脚本和CSS挂接到< head>中?

问题描述

我正在制作的模块的事情是，它会生成一个javascript代码段，因此我不能使用操作将其挂接到HTML部分中，因为该操作需要我有一个JS文件(请纠正我如果我错了).我可以通过哪些方式将JavaScript代码段添加到代码中?我当时在考虑使用一个块，但是我不确定该块后面应该附加什么，因此我不得不考虑这将适用于所有主题.

The thing with the module I am making is that it kind of generates a javascript snippet, so I cannot use an action to just hook that into the section of the HTML since the action requires that I have a JS file (correct me if I am wrong). What are some ways for me to put a JavaScript snippet into the tag? I was thinking of using a block, but I am not sure what the block should be appended after and I have to consider that this will work with all themes.

推荐答案

库存模板是

template/page/html/head.phtml

以您自己的主题复制该文件将是获得一些javascript的最简单方法.

Copying that file in your own theme would be the simplest way to get some javascript in the head.

尽管(从开发人员的角度来看)更好，但是此模板包括以下行

Better though (from a developer point of view), this template includes the following line

<?php echo $this->getChildHtml() ?>

关于链接将打印出一个块的所有子块.因此，将一个子块添加到head块也将起作用.

The about link prints out all the child blocks of a block. So, adding a child block to the head block would also work.

<layouts>
    <default> <!-- does this to all pages — use specific layout handles to target a page -->
        <reference name="head"> <!-- get a reference to the existing head block -->
            <block type="core/text" name="simple_example_javascript_block"> <!-- append a simple text block, probably better to use a new template block -->
                <action method="setText"> <!-- set our new block's text -->
                    <text><![CDATA[
                    <script type="text/javascript">
                        alert("foo");
                    </script>
                    //]]></text>
                </action>
            </block>
        </reference>
    </default>
</layouts>

上面的XML使用简单的core/text块将javascript添加到每个Magento页面. local.xml中的作品，应该在其他地方工作.我敢肯定，可以想到更好的方法(例如，模板块)

The above XML uses a simple core/text block to add javascript to every Magento page. Works from local.xml, should work elsewhere. I'm sure better ways to do this should spring to mind (template block, for example)
