EvalError - JavaScript 编辑

The EvalError object indicates an error regarding the global eval() function. This exception is not thrown by JavaScript anymore, however the EvalError object remains for compatibility.

Constructor

EvalError()

Creates a new EvalError object.

Instance properties

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.

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"
}
