Question

Is it possible (using jQuery or otherwise) to listen for a change in the value of a non-DOM Javascript object (or variable)?

So, for instance, I have:

function MyObject(){
    this.myVar = 0;
}

var myObject = new MyObject();
myObject.myVar = 100;

Is there a way to listen for when the value of myVar changes and call a function?

I know that I could use getter/setters, but they aren’t supported in previous versions of IE.

Answer 1

If IE is important, I guess you are not interested in Watch

But someone seems to have written a shim which makes this question a duplicate
