Value-based JavaScript object prototype

Is there a way to ensure that every new object I create has its own unique dataTransfer property? For instance, when I try something like 

Object.prototype.dataTransfer = new DataTransfer();
, I want a.dataTransfer.prop to remain 1 even if b.dataTransfer.prop is set to 2. How can I achieve this?

To give an example:

a.dataTransfer.prop to continue being equal to 1, not 2.



My goal context here involves attempting to modify WebKit and IE behavior related to the .dataTransfer object in drag and drop events for proper functionality.

Answer №1

Typically, the best practice would be to include it in the constructor function. However, given that you aim to extend a host object like HTMLDomElement, achieving this may prove challenging. Nevertheless, if you expand your problem statement beyond specific implementation details, there might be an alternative approach to consider. This could involve utilizing a library with a varying user interface depending on the browser being used, effectively abstracting the browser and providing a consistent API.
