Name

DOMException — an exception thrown by a Web API

Synopsis

Most client-side JavaScript APIs throw DOMException objects when they need to signal an error. The code and name properties of the object provide more details about the error. Note that a DOMException can be thrown when reading or writing a property of an object as well as when calling a method of an object.

DOMException is not a subclass of the core JavaScript Error type, but it functions like one, and some browsers include a message property for compatibility with Error.
