Embed javascript in markdown

问题

I'm using the Maruku markdown processor. I'd like this

*blah* blah "blah" in [markdown](blah)

<script src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
<script>
...do stuff...
</script>

but it complains when I render it with a multitude of errors. The first one being

 ___________________________________________________________________________
| Maruku tells you:
+---------------------------------------------------------------------------
| Could you please format this better?
| I see that "<script type='text/javascript'>" is left after the raw HTML.
| At line 31
|   raw_html     |<script src='http://code.jquery.com/jquery-1.4.2.min.js' /><script type='text/javascript'>|
|       text --> |//<![CDATA[|

and then the rest seems like the parser is going nuts. Then it renders the javascript into a div on the page. I've tried making it a CDATA block and extra spacing between the jquery and my script.

Help?

回答1:

I had this same problem, but I managed to get JavaScript to appear in my code by putting a newline after the opening tag.

Different solution that might work in some cases: (the selected answer didn't work for me when I was trying to embed a CodePen example)

add this to your default layout:

<!-- Custom JavaScript files set in YAML front matter -->
{% for js in page.customjs %}
<script async type="text/javascript" src="{{ js }}"></script>
{% endfor %}

In posts where you need some JavaScript files, you can add them in the YAML front matter like so:

---
layout: post
title: Adding custom JavaScript for a specific post
category: posts
customjs:
 - http://code.jquery.com/jquery-1.4.2.min.js
 - http://yourdomain.com/yourscript.js
---

The async might not be necessary or wanted but you could probably add that as a parameter in customjs. (see YAML front matter for Jekyll and nested lists for details)

回答3:

Markdown supports inline XHTML but not Javascript.

回答4:

The example they give on their site shows an empty <script> tag containing a newline. Maybe that's it?

回答5:

You could use pandoc, which handles this input (and javascript generally) just fine.

回答6:

I found that escaping the closing '>' symbol in both, the opening and closing 'script' tags, will display it correctly, for example:

If you type the follwing:

<script\>... javascript code...</script\>

It will be rendered like this:

<script>... javascript code...</script>

That's just my two cents.

回答7:

To my experience, markdown will outpus javascript text as plain text as long as you remove the code formatting that may confuse markdown.

remove comments from javascript, as /* ... */ is translated to < em>
remove the space indent in the front of each line. < p> may be inserted according to your indentation.

Basically what I do is to review the generated html and find out what extra tags are inserted in between my javascript code by markdown. And remove the formatting that generates the extra tag.

A good idea is to have local and cloud js sources separated:

In the post file:

cloudjs:
 - //cdnjs.cloudflare.com/ajax/libs/d3/3.5.3/d3.min.js
 - //cdnjs.cloudflare.com/ajax/libs/topojson/1.6.9/topojson.min.js
localjs:
 - datamaps.world.min.js
 - custom.js

In the default file after footer inclusion:

   {% for js in page.cloudjs %}

        <script type="text/javascript" src="{{ js }}"></script>

    {% endfor %}


    {% for js in page.localjs %}

        <script type="text/javascript" src="{{ "/assets/scripts/" | prepend: site.baseurl | append: js }}"></script>

    {% endfor %}

回答9:

Just indent the first line contains < script > tag.
