Question

Have following code.

object.waypoint=function () {
    this.uw=setInterval( function() {
       console.log(this);
    }, 200);
}

How do I refer to “object” inside function on line three, I tried it with “this” keyword but it doesn’t seem to refer the object.

Answer 1

Inside setInterval this refers to window. You’ll need to make a variable that references to this.

object.waypoint=function () {
    var me = this;

    this.uw=setInterval( function() {
       console.log(me);
    }, 200);
}
