var aa = function () {    log("xxxx");};aa();var model = {};model.test = function () {    log("model.test");};model.test();function log(msg) {    var info = stackInfo();    var method = info[‘method‘];    var file = info[‘file‘];    var line = info[‘line‘];    console.log("(" + method + ") <" + file + ":" + line + "> " + msg);}
// 這裡是主要方法function stackInfo() {    var path = require(‘path‘);    var stackReg = /at\s+(.*)\s+\((.*):(\d*):(\d*)\)/i;    var stackReg2 = /at\s+()(.*):(\d*):(\d*)/i;    var stacklist = (new Error()).stack.split(‘\n‘).slice(3);    var s = stacklist[0];    var sp = stackReg.exec(s) || stackReg2.exec(s);    var data = {};    if (sp && sp.length === 5) {        data.method = sp[1];        data.path = sp[2];        data.line = sp[3];        data.pos = sp[4];        data.file = path.basename(data.path);    }    return data;}

輸出格式內容：

(aa) <c.js:6> xxxx
(Object.model.test) <c.js:12> model.test
