How to print a message in error handling with try, catch

Question

I have a simple example:

var str = '{ "test"  : 1, }'  try {     JSON.parse(str); } catch (e) {     console.log(e) } 

result:

[SyntaxError: Unexpected token }]

How to print all error info ?

Expected result:

undefined:1 { "test"  : 1, }          ^ SyntaxError: Unexpected token } 

Answer 1

This will help:

var x = { asd: "asd", };  try {     JSON.parse(x); } catch (e) {     console.log("Error", e.stack);     console.log("Error", e.name);     console.log("Error", e.message); } 

error.stack is not exactly what you want, but it will help you.

This will show you the various ways in which you can get the info available:

var str = '{"test": 1, }';  try {     JSON.parse(str); } catch(e) {      console.log("error object:");     console.log(e);     console.log();      console.log("error object toString():");     console.log("\t" + e.toString());      console.log();     console.log("error object attributes: ");     console.log('\tname: ' + e.name + ' message: ' + e.message + ' at: ' + e.at + ' text: ' + e.text);      console.log();     console.log("error object stack: ");     console.log(e.stack); } 

The output is:

error object: [SyntaxError: Unexpected token }]  error object toString():     SyntaxError: Unexpected token }  error object attributes:      name: SyntaxError message: Unexpected token } at: undefined text: undefined  error object stack:  SyntaxError: Unexpected token }     at Object.parse (native)     at Object.<anonymous> (/home/james/devel/tests/node/test.js:4:10)     at Module._compile (module.js:449:26)     at Object.Module._extensions..js (module.js:467:10)     at Module.load (module.js:356:32)     at Function.Module._load (module.js:312:12)     at Module.runMain (module.js:492:10)     at process.startup.processNextTick.process._tickCallback (node.js:244:9) 

You can take your pick :-)
