EvalError instances

Properties

EvalError.prototype.constructor

Specifies the function that created an instance's prototype.

EvalError.prototype.message

Error message. Although ECMA-262 specifies that EvalError should provide its own message property, in SpiderMonkey, it inherits Error.prototype.message.

EvalError.prototype.name

Error name. Inherited from Error.

EvalError.prototype.fileName

Path to file that raised this error. Inherited from Error.

EvalError.prototype.lineNumber

Line number in file that raised this error. Inherited from Error.

EvalError.prototype.columnNumber

Column number in line that raised this error. Inherited from Error.

EvalError.prototype.stack

Stack trace. Inherited from Error.

Methods

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

Examples

EvalError is not used in the current ECMAScript specification and will thus not be thrown by the runtime. However, the object itself remains for backwards compatibility with earlier versions of the specification.

Creating an EvalError

try {
  throw new EvalError('Hello', 'someFile.js', 10);
} catch (e) {
  console.log(e instanceof EvalError); // true
  console.log(e.message);              // "Hello"
  console.log(e.name);                 // "EvalError"
  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"
}
