Download jQuery plugin from String

Question

I want to do something a little hacky.

Say I have jQuery plugin code in this variable:

var script = '!function( some jQuery plugin )(window.jQuery)';

I want to download it. I tried eval (script) and jQuery.globalEval (script). This does not work. If I had this pluggable code in a file, I could do jQuery.getScript (url, callback). But I only have code in the line. I was thinking about loading this line into the cache associated with the mock URL, but I don't know if this is possible.

Any suggestions? ... other than "don't do this." I know that the "eval is evil" mantra, but think of it as an academic matter.

Key code features in a script variable:

Prologue:

!function(a){"use strict";

Epilogue:

gister(b)})}}(window.jQuery||window.Zepto);
