URIError() constructor

The URIError() constructor creates URIError objects.

Syntax

js

new URIError()
new URIError(message)
new URIError(message, options)
new URIError(message, fileName)
new URIError(message, fileName, lineNumber)

URIError()
URIError(message)
URIError(message, options)
URIError(message, fileName)
URIError(message, fileName, lineNumber)

Note: URIError() can be called with or without new. Both create a new URIError instance.

Parameters

message Optional

Human-readable description of the error.

options Optional

An object that has the following properties:

cause Optional

A property indicating the specific cause of the error. When catching and re-throwing an error with a more-specific or useful error message, this property can be used to pass the original error.

fileName Optional

The name of the file containing the code that caused the exception.

lineNumber Optional

The line number of the code that caused the exception.

Examples

Catching an URIError

js

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 an URIError

js

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
}
