Question

I want to write a query parsing method that would belong to the location class, but am not having any luck with

window.location.prototype

or

window.prototype

My goal is to do something along the lines of:

window.location.prototype.parseQuery = function(key){
   //run a test on this.search to see if it contains key and return the val
}

Is window immutable? or am I just not referencing it correctly?

TIA

You don’t need the prototype when the object already exists and there’s only one of them. You can just add a method directly to the object.

window.parseQuery = function() { /* your code here */};

or

window.location.parseQuery = function() { /* your code here */};

Also, the window object is the global object in a browser so any global function is already a method on the window object.
