    Parameters

    message

    fileName
    Optional. The name of the file containing the code that caused the exception
    lineNumber

    Description

    A URIError is thrown when the global URI handling functions are passed a malformed URI.

    Properties

    URIError.prototype
    Allows the addition of properties to a URIError object.

    URIError instances

    Properties

    URIError.prototype.constructor
    Specifies the function that created an instance's prototype.
    URIError.prototype.message
    Error message. Although ECMA-262 specifies that URIError should provide its own message property, in SpiderMonkey, it inherits Error.prototype.message.
    URIError.prototype.name
    Error name. Inherited from Error.
    URIError.prototype.fileName
    Path to file that raised this error. Inherited from Error.
    URIError.prototype.lineNumber
    Line number in file that raised this error. Inherited from Error.
    URIError.prototype.columnNumber
    Column number in line that raised this error. Inherited from Error.
    URIError.prototype.stack
    Stack trace. Inherited from Error.

    Methods

    Although the URIError prototype object does not contain any methods of its own, URIError instances do inherit some methods through the prototype chain.

    Examples

    Example: Catch an 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.fileName);            // "Scratchpad/1"
      console.log(e.lineNumber);          // 2
      console.log(e.columnNumber);        // 2
      console.log(e.stack);               // "@Scratchpad/2:2:3\n"
    }
    

    Example: Create an URIError

    try {
      throw new URIError('Hello', 'someFile.js', 10);
    } catch (e) {
      console.log(e instanceof URIError); // true
      console.log(e.message);             // "Hello"
      console.log(e.name);                // "URIError"
      console.log(e.fileName);            // "someFile.js"
      console.log(e.lineNumber);          // 10
      console.log(e.columnNumber);        // 0
      console.log(e.stack);               // "@Scratchpad/2:2:9\n"
    }
