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();

您好，我正在使用此代码，但是当我尝试执行console()时，出现此错误：TypeError: console.log is not a function

我该怎么做才能解决此问题？

Answer 1

之所以得到obj.position，是因为您用自己的名为var obj = new THREE.Mesh( new THREE.PlaneGeometry(3, 2, 1, 1), new THREE.MeshLambertMaterial({color:0x00aa00,transparent:true,side:THREE.DoubleSide}) ); obj.geometry.translate(3,2,0); obj.position.copy(new THREE.Vector3(3.0, 2, 0.0)); var box = new THREE.Box3().setFromObject( obj ); box.getCenter( obj.position ); // this re-sets the obj position obj.geometry.center();的函数覆盖了TypeError: console.log is not a function对象，而该函数没有console函数。您可以通过将函数重命名为其他内容来解决此问题，如代码段示例：

console

Answer 2

全局window对象已经具有一个名为console的函数，您正在尝试使用自己的console函数覆盖该函数。只需将您的console函数重命名为其他名称即可。

Answer 3

您无法命名函数console

原因-Console是JavaScript中的现有对象，可用于访问浏览器的调试控制台。阅读MDN web docs了解更多信息

更正的代码

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();

Console.log不输出json
