Question

EDITED:

Just wondering if is it possible to add a function (or static script) block or a variable to body of html.

Something like this,

$('body').add(function(){/../}) 

or

$('body').append('<script></script>')

or

$('body').fn.myFunc = function(){}

Is it correct to use .extend instead?

One example is if I use ExternalInterface, my callbacks have to be statically defined in body/html/js but not in $().ready function unless I have a var defined globally and refer it in $().ready function.

I overlooked this requirement, and thats where I wanted to add dynamic callback functions.

• To create a script tag in your markup

  $('<script/>', {
      type:    'text/javascript',
      src:     'http://...'
  }).appendTo(document.body);
  

• To extend jQuery use

  $.fn.yourmethodname = function(){
  });
