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.
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);
}
A common way is to store a reference to this in a variable, that you then can use to get access to the proper this:
object.waypoint=function () {
// Keep a reference to this in a variable
var that = this;
that.uw=setInterval( function() {
// Now you can get access to this in here as well through the variable
console.log(that);
}, 200);
}
I think bind is a neat solution - It isn't implemented in all browsers but there are workarounds.
object.waypoint = function(){
this.uw = setInterval(function(){
console.log(this);
}.bind(this), 200);
}
See the MDN page for proper documentation
