Prevent unauthorized manipulation of specific objects' hrefs in Javascript / Identify the source of href modifications

I am currently dealing with an outdated application that populates a div by initiating a JavaScript function on a remote server and then injecting the resulting content into the DOM.

Interestingly, when using Firefox, the application unexpectedly alters all URL hosts to a different address.

This peculiar behavior does not occur in Chrome or IE.

Although I aim to resolve this issue by fixing the application itself, my immediate concern is whether it's feasible to write custom JavaScript code to "safeguard" certain elements within the document from being tampered with (such as the href attribute of specific objects).

Is such protection even achievable?

Moreover, could there be a way to leverage developer tools in order to pinpoint the exact line of script causing the domain of my links to undergo changes?

Answer №1

Make a property read-only using Object.defineProperty().

 Object.defineProperty(obj, "key", {
    enumerable: false,
    configurable: false,
    writable: false,
    value: "static"
 });

Source:

Check out the defineProperty MDN Reference here

Note:

If you need to support old browsers that do not support defineProperty, consider using closures to protect your data from external manipulation. By providing getters for others to access your read-only data, you can ensure its integrity.
