How to get the instance name of an object

Question

I use the below code to write code to query a web method in a specified interval.

now in the this.Poll function I have to do

this.tmo = setTimeo

You can use this handy little wrapper to execute a function periodically at given interval (1 sec by default):

function tick(func, interval) {
    return (function() {
        if(func())
            setTimeout(arguments.callee, interval || 1000);
    })();
}

The function is repeated until it returns false:

tick(function() {
   if(should stop) return false;
   do stuff
   return true;
});

If the function is a method, make a closure as shown

// inside your object
var me = this;
tick(function() {
   return me.doStuff();
});
