语法:
console.trace(label)

label
例子:
console.trace(); //运行结果: Trace: at Object.<anonymous> (/home/byvoid/consoletrace.js : 1: 71) at Module._compile (module.js:441:26) at Object..js (module.js:459:10) at Module.load (module.js:348:31) at Function._load (module.js:308:12) at Array.0 (module.js:479:10) at EventEmitter._tickCallback (node.js:192:40)
源码:
Console.prototype.trace = function() { // TODO probably can to do this better with V8's debug object once that is // exposed. var err = new Error; err.name = 'Trace'; err.message = util.format.apply(this, arguments); Error.captureStackTrace(err, arguments.callee); this.error(err.stack); };
