Why won't this Javascript method keep calling itself?

Question

I have a JavaScript object with a privileged method. When this method has completed, I would like it to call itself (after a small timeout) and continue running indefinitely

Answer 1

Try

function Test() {
    // ... private variables that testMethod needs to access ...
    this.testMethod = function() {
        alert("Hello, from the method.");
        var self = this;
        setTimeout(function() { self.testMethod(); }, 2000);
    };
}

or use setInterval.
