This plugin adds 3 fields on every page and blog post where you can type your code in a readable interface.
In addition to being very light and functional, the WP Custom Code plugin also allows you to work with external libraries. Basque paste the address 
of the javascript library of your choice in the designated field and you will be able to enjoy this indispensable resource.

WP Custom Code

Add CSS and Javascript to your pages simply and quickly. WP Custom Code supports CodeMirror.

The Save Me plugin saves JavaScript and other inline code from distortion by the WordPress rich text editor. Add code in the editor’s VISUAL mode, bracketing it with the shortcode <code>[saveme][/saveme]</code>.
While it is possible without a plugin to switch to HTML editing mode and paste JavaScript into a post, often the code will be scrambled if you toggle back and forth between the HTML and Visual modes. For example, the TinyMCE editor sometimes eliminates what it doesn’t understand — like empty divs into which your JavaScript or AJAX widget needs to inject content. And since JavaScript code is not displayed with any representation in the visual editor, it’s easy to accidentally delete.
In rich tech mode, the editor will treat your code as if it were a code sample you were writing about, rather than a script to be executed. You may see distortions, like quotation marks being turned into curly quotes, but at least you can keep track of where you inserted the code. The saveme shortcode function reverses HTML entity transformations and turns your JavaScript widget back into executable code.
The saveme shortcode has been tested with Facebook social widgets and Google Adsense JavaScript blocks. If you encounter JavaScript that does not work after being passed through this function, contact me through <a href="http://www.carrcommunications.com/" rel="nofollow ugc">Carr Communications Inc.</a> and I will try to determine why not.
This is a spinoff of a similar function in <a href="http://www.carrcommunications.com/wordpress-plugins/facebook-tab-manager/" rel="nofollow ugc">Facebook Tab Manager for WordPress</a>
