如何将Jquery对象从父iframe注入到嵌入式iframe？

Question

I am embedding an iframe in a webpage and I want to inject jquery in this frame.

I tried something like:

frame.contentWindow.$ = window.$

While this works, the iframe's $ is still running in the parent's scope as opposed to its own independent copy.

Is there a way to inject an independent jquery object into the iframe without injecting a <script src="/path/to/jquery.js"></script> in the frame?

UPDATE

Solved it. The jquery.js conveniently defines jQuery for a scope by accepting the window object in an anonymous function:

function(windowObject){ .... define jquery }(window)

So all I had to do was to name this function, Eg jQuerify and call it once for the parent window object and then for the child window object.

jQuerify = function(windowObject){ .... define jquery }
jQuerify(window)
jQuerify(iframe.contentWindow)

You can try cloning the jQuery object:

See this answer or this one on how to implement a .clone function, then call this:

iframe.contentWindow.$ = window.$.clone();

or

iframe.contentWindow.$ = window.$.bind({});

... depending on how you choose to clone the function.
