Question

Can someone tell me what object this.onSubmit is referring to in the following code?

(function () {
    var _d = vjo.dsf.EventDispatcher;
    var _r = vjo.Registry;

    function $1(p0) {
        return function (event) {
            return this.onSubmit(p0, event);
        };
    };
})();

I apologise if there is not enough context attached to this example.

Answer 1

In JavaScript, the value of this is dynamically set. So to know its value, you need to know how the function is being called/used.

So the generic answer would be that this is referring to whatever was set as the this value of the execution context.
