Which one is better for window.parent.location.href or window.top.location

Question

I work in a project where I have to redirect errors to a page in a specific scenario. To do this, I created the Error.aspx page. Right now I am using window.top.location.href = "../Error.aspx" and it generates http: //localhost/app_web/Error.aspx and its working fine except for one (which shows the message http: // xyz /ErrorPage.aspx 'does not exist.). So can anyone suggest which option is better for this.

thank

• window.parent.location

• window.top.location

  • "".
  • It returns the location of the topmost window in the window hierarchy.
  • If there is no parent in the window, top is a reference to itself (window === window.top)
