The EvalError
constructor creates a new error regarding
the global eval()
function. This exception is not
thrown by JavaScript anymore, however the EvalError
object remains for
compatibility.
Syntax
new EvalError([message[, fileName[, lineNumber]]])
Parameters
message
Optional- Human-readable description of the 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
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"
}
