Extension:AddHTML

Better Option
See SecureHTML extension for a better solution.

Features

 * Secure: Only people who can edit 'protected' pages (sysops) can use the tag
 * Inserts HTML code section either through:
 * inline code without the tagged section e.g. code here
 * or through PHP code
 * Parser Cache friendly

Limitation
The tag can only be used on pages which are 'protected', which means you might be forced to protect a page in order to use some HTML, which otherwise you would permit open editing on.

Example1
and use an extension such as to populate the section # 'xyz' with HTML code.

Example2
 function disp_prompt { var name=prompt("Please enter your name","t3h h4x0r") if (name!=null && name!="") {   document.write("Hello " + name + "! How are you today?") } } 

Security
Pages where 'addhtml' is used must be protected or else an 'unauthorized use of addhtml' message will be displayed. If you have several 'sysop' users, you must trust them all not to abuse this feature.
