BR javascript firefox-addon share|improve console is not defined node js this question asked Jan 4 at 16:42 Pan Ruochen 5981720 Please edit your question to be on-topic: Questions seeking debugging help ("why isn't this code working?") must include: •the desired behavior, •a specific problem or error and •the shortest code necessary to reproduce it in the question itself. Questions without a clear problem statement are not useful to other readers. See: How to create a Minimal, Complete, and Verifiable Example, What topics can I ask about here?, and How do I ask a good question?. –Makyen May 28 at 22:45 Please format error messages either in code format (which preserves line formatting; this is normally preferred), or as quotations. Either format makes the error clearly stand out from the other text in your question. As it is, it is not easy to tell at a glance what is error text and what is not. –Makyen May 28 at 23:13 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote Try importing it like this Cu.import('resource://gre/modules/devtools/Console.jsm'); share|improve this answer answered Jan 5 at 1:03 Noitidart 11.4k52162 It works........ –Pan Ruochen Jan 5 at 3:51 There's an about:config setting

What went wrong? There is a non-existent variable referenced somewhere. This variable needs to be declared, or you need make sure it is available in your current script or scope. Note: When loading a library (such as jQuery), make sure it is loaded before you access library variables, such as "$". Put the script tag that loads the library before your code that uses it. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Not_defined Examples Variable not declared foo.substring(1); // ReferenceError: foo is not defined The "foo" variable isn't defined anywhere. It needs to be some string, so that the String.prototype.substring() method will work. var foo = "bar"; foo.substring(1); // "ar" Wrong scope A variable need to be available in the current context of execution. Variables defined inside a function cannot be accessed from anywhere outside the function, because the variable is defined only in the scope of the function function numbers () { var num1 = 2, num2 = 3; return num1 + num2; } console.log(num1); // ReferenceError num1 is not defined. However, a function can access all variables and functions defined inside the scope in which it is defined. In other words, a function defined in the global scope can access all variables defined in the global scope. var num1 = 2, num2 = 3; function numbers () { return num1 + num2; } console.log(num1); // 2 See also Scope Declaring variables in the JavaScript Guide Function scope in the JavaScript Guide Document Tags and Contributors Tags: Error JavaScript ReferenceError Contributors to this page: fscholz Last updated by: fscholz, May 23, 2016, 2:49:42 AM See also JavaScript Tutorials: JavaScript Guide Introduction Grammar and types Control flow and error handling Loops and iteration

to log client-side errors and report them to your servers. It’s also one of the major mechanisms by which Sentry’s client JavaScript integration (raven-js) works. You listen to the onerror event by assigning a function to window.onerror: window.onerror = function (msg, url, lineNo, columnNo, error) { // ... handle error ... return false; } When an error is thrown, the following arguments are passed to the function: msg – The message associated with the error, e.g. “Uncaught ReferenceError: foo is not defined” url – The URL of the script or document associated with the error, e.g. “/dist/app.js” lineNo – The line number (if available) columnNo – The column number (if available) error – The Error object associated with this error (if available) The first four arguments tell you in which script, line, and column the error occurred. The final argument, Error object, is perhaps the most valuable. Let’s learn why. The Error object and error.stack At first glance the Error object isn’t very special. It contains 3 standardized properties: message, fileName, and lineNumber. Redundant values that already provided to you via window.onerror. The valuable part is a non-standard property: Error.prototype.stack. This stack property tells you at what source location each frame of the program was when the error occurred. The stack trace can be a critical part of debugging an error. And despite being non-standard, this property is available in every modern browser. Here’s an example of the Error object’s stack property in Chrome 46: "Error: foobar\n at new bar (
