Probably obvious, but still confusing me.
Is it in anyway possible to call from an another object's prototype a prototype inside another object?
Current set:
function obj1() {
this.myVar = 1;
}
obj1.prototype.helloWorld = function() {
alert("Hello world!");
}
function obj2() {
this.myVar = 2;
}
obj2.prototype.nonSense = function() {
console.log(this.myVar);
}
1. Can Obj2
prototype nonSense
somehow call the prototype helloWorld
in Obj1
?**
2. Can Obj2
prototype nonSense
somehow access the Obj1
variable myVar
?
I'm not really sure what you're trying to do but you can call the helloWorld
method directly:
obj1.prototype.helloWorld();
If you have an instance of obj1
, you can get rid of the prototype
:
var myObj1 = new obj1();
myObj1.helloWorld();
To access myVar
from outside of obj1
you will need to have called obj1
- myVar
won't exist until you have called the function in which it is declared. Most likely, you will want to create an instance of obj1
by calling it with the new
operator, as shown above. You can then access myVar
just like any other property:
console.log(myObj1.myVar);
