SID-00715: How to embed Javascript in a page?

For the life of me I can't get JavaScript to work!

I edit a page, click "Edit HTML Source", and get the HTML editor as expected.

I add this to the HTML: <script type="text/javascript"> alert(0); </script>

Pretty vanilla stuff... should just pop an alert on page load.

I click "Update" and the JS isn't displayed in the WYSIWYG editor (perhaps expected).

I save the edit.

The newly edited content is rendered, but I get no popup.

I click Edit again. The JS now appears in WYSIWYG view as <script type="text/javascript">// </script>

Viewing it in TWiki Markup mode this is:

<script type="text/javascript">// <![CDATA[ alert(0); // ]]></script>

Viewing the HTML source it's:

<p><span class="WYSIWYG_PROTECTED"><script type="text/javascript"></span>// <![CDATA[ alert(0); // ]]><span class="WYSIWYG_PROTECTED"></script></span></p>

It seems that somewhere along the line the JS is being converted from script code (that can execute) to "a displayed representation of JavaScript" (which looks nice but does nothing).

So, what's the trick to editing JavaScript that gets saved as javaScript and therefore actually executes?

Discussion and Answer

Try the <sticky>..</sticky> tags to delimit HTML (or TML) that you do not want to be WYSIWYG edited. See TinyMCEPlugin.
