URIError

The URIError object represents an error when a global URI handling function was used in a wrong way.

URIError is a serializable object, so it can be cloned with structuredClone() or copied between Workers using postMessage().

URIError is a subclass of Error.

Constructor

• URIError()
  • : Creates a new URIError object.

Instance properties

Also inherits instance properties from its parent Error.

These properties are defined on URIError.prototype and shared by all URIError instances.

• URIError.prototype.constructor
  • : The constructor function that created the instance object. For URIError instances, the initial value is the URIError constructor.
• URIError.prototype.name
  • : Represents the name for the type of error. For URIError.prototype.name, the initial value is "URIError".

Instance methods

Inherits instance methods from its parent Error.

Examples

Catching a URIError

try {
  decodeURIComponent("%");
} catch (e) {
  console.log(e instanceof URIError); // true
  console.log(e.message); // "malformed URI sequence"
  console.log(e.name); // "URIError"
  console.log(e.stack); // Stack of the error
}

Creating a URIError

try {
  throw new URIError("Hello");
} catch (e) {
  console.log(e instanceof URIError); // true
  console.log(e.message); // "Hello"
  console.log(e.name); // "URIError"
  console.log(e.stack); // Stack of the error
}
