Console.log 不输出 json

Question

 var _json = [{"codigo": "1", "nome": "Robert Santos", "turma": "EM2A"}, {"codigo": "2", "nome": "Eduardo Alves Silveira", "turma": "EM3A"}, {"codigo": "3", "nome": "Amara Gouveia", "turma": "EMT2B"}, {"codigo": "4", "nome": "Tainá Belchior da Silva", "turma": "EF5B"}]; function console() { console.log(JSON.stringify(_json, null, 4)); } console();

Hi, i'm using this code, but when I try execute console() , i'm getting this error: TypeError: console.log is not a function

What should I do to fix this problem?

Answer 1

You're getting TypeError: console.log is not a function because you're overwriting the console object in the global scope with your own function called console which doesn't have a log function. You can solve this issue by renaming your function to something else, snippet example:

 var _json = [{"codigo": "1","nome": "Robert Santos","turma": "EM2A"}, {"codigo": "2","nome": "Eduardo Alves Silveira","turma": "EM3A"},{"codigo": "3","nome": "Amara Gouveia","turma": "EMT2B"},{"codigo": "4","nome": "Tainá Belchior da Silva","turma": "EF5B"}]; function log() { console.log(JSON.stringify(_json, null, 4)); } log();

Answer 2

The global window object already has a function named console , which you are trying to override with your own console function. Just rename your console function to something else.

Answer 3

You cannot name your function console

Reason - Console is an existing object in JavaScript that provides access to the browser's debugging console. Read MDN web docs to know more about it

Corrected Code

 var _json = [{"codigo": "1","nome": "Robert Santos","turma": "EM2A"}, {"codigo": "2","nome": "Eduardo Alves Silveira","turma": "EM3A"},{"codigo": "3","nome": "Amara Gouveia","turma": "EMT2B"},{"codigo": "4","nome": "Tainá Belchior da Silva","turma": "EF5B"}]; function logger() { console.log(JSON.stringify(_json, null, 4)); } logger();
