SyntaxError object represents an error when trying to interpret syntactically invalid code. It is thrown when the JavaScript engine encounters tokens or token order that does not conform to the syntax of the language when parsing code.

实例特性

SyntaxError.prototype.message

SyntaxError.prototype.name

Error name. Inherited from Error .

SyntaxError.prototype.fileName

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

SyntaxError.prototype.lineNumber

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

SyntaxError.prototype.columnNumber

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

SyntaxError.prototype.stack

Stack trace. Inherited from Error .

范例

Catching a SyntaxError

try {
  eval('hoo bar');
} catch (e) {
  console.error(e instanceof SyntaxError);
  console.error(e.message);
  console.error(e.name);
  console.error(e.fileName);
  console.error(e.lineNumber);
  console.error(e.columnNumber);
  console.error(e.stack);
}
					

Creating a SyntaxError

try {
  throw new SyntaxError('Hello', 'someFile.js', 10);
} catch (e) {
  console.error(e instanceof SyntaxError); // true
  console.error(e.message);                // Hello
  console.error(e.name);                   // SyntaxError
  console.error(e.fileName);               // someFile.js
  console.error(e.lineNumber);             // 10
  console.error(e.columnNumber);           // 0
  console.error(e.stack);                  // @debugger eval code:3:9
}
