Tips for isolating all the Javascript loaded via ajax or jquery.load within a specific child scope instead of a global scope

I am currently working on a solution to embed a third-party page into my site using ajax/jquery.load() to avoid using iframes (CORS requirements are already handled by the third party).

My dilemma lies in the fact that the main host site loads jquery 1.x and other libraries, while the third-party page loads jquery 2.x and conflicting libraries.

How can I restructure the JavaScript on the third-party page so that it is contained within a shielded child scope instead of the global scope?

Is wrapping everything in function(){} sufficient? And how would I access methods/variables within this child scope on the third-party page?

Please advise if more information is needed for further assistance...

Answer №1

iframes typically load an entire document independently and are designed to be isolated from external interference. However, you can enable features like modals or popups using the sandbox attribute. If no attribute is specified, the iframe will only display content without interacting with other layers.

To access a function within an iframe, you can use the following code:

document.getElementById("resultFrame").contentWindow.Reset()

This code will execute the Global Function Reset() inside the iframe with the ID of resultFrame.
