Hopefully this is an "easy" one.
I have a page that creates an Instance of a Class. Then the Class Instance is sent to another page using page.postMessage(); When I receive the data on the other page, and I check the received data to see if the object is an Instance of the Class, it always fails, presumably because I am missing a step.
Properties Page:
class MyClass {
constructor(name, value){
this.name = name;
this.value = value;
}
}
const foo = new MyClass("bob", 123);
window.postMessage( { myMsg : foo });
function messageListener(msg){
console.log(msg.data.myMsg instanceof MyClass); // Always returns false
}
I left a lot of code out of the examples but basically using Modules so the same class constructor is available on both pages.
I would like to be able to check the data on the receiving page to see if the object is an instance of the class.
What am I doing wrong? Most importantly, how can I check on the receiving page to see if the received data is an instance of the class?
Try printing just:
to see if you actually have the proper data/object inside.
