Javascript variable undefined in IE until console displayed - javascript

I have a small piece of code for a template project I'm working on. There are three separate buttons, that point to three separate locations. In order to make it easier for content providers, I have these buttons calling minimal routines to load the next page.
The code is as follows:
/* navigation functions here for clarity and ease of editing if needed */
prevURL = 'ch0-2.html';
nextURL = 'ch2-1.html';
manURL = 'ch1-2.html';
function prevPage() {
window.location = prevURL;
}
function nextPage() {
window.location = nextURL;
}
function goManager() {
window.location = manURL;
}
This works perfectly in Firefox and Chrome, but seems to fail in Internet Explorer.
I open up the developer tools in IE (F12) and am presented with the message:
SCRIPT5009: 'manURL' is undefined
The location information (line 43, character 13) points to the "window.location = manURL" part of the code.
However, once the developer tools are open, if I hit F5 to reload the page, the button works without error until I close IE and reopen it, where it once again fails to respond and gives the same "undefined" error.
I'm baffled. Anyone have any ideas?
UPDATE
I know the variable declaration is poor, and that I can use window.location.href instead. What is relevant here is that the other two pieces of code, which are identical in all of these significant ways, work perfectly either way.
epascarello has put me on the right track. by removing all console.log commands, everything starts working. I'm just wondering why this happens, and would like to be able to give epascarello credit for helping me.

IE does not have console commands when the developer window is not open. So if you have them in there the code will not run. It will error out.
You can either comment out the lines or add in some code that adds what is missing.
if (typeof console === "undefined") {
console = {
log : function(){},
info : function(){},
error : function(){}
//add any others you are using
}
}

Try setting
window.location.href
instead of just window.location.

Always define variables before using them ,being explicit (expressing the intention) is a good practice,
so define your variables like this,
var prevURL = 'http://google.com';
var nextURL = 'http://msn.com';
var manURL = 'http://stackoverflow.com';
You can try using
window.location.href

Why Chrome don't allow change variables in debug

I run in Chome devtools next code
(function() {
var a = 5;
debugger; // when I stop here I evaluate `a = 9`
console.log(a);
})(); // and got 5
but if I use
(function() {
var a = { a: 5 };
debugger; // when I stop here I evaluate `a.a = 9`
console.log(a.a);
})(); // and got 9
Why?
PS
also why it doesn't work in FF / Safari (it even didn't stop in debugger line )
This is behavior is simply a bug, and will be fixed in an upcoming release.
If you want a "why" deeper than that, you'll need to know a lot about Chrome's debugger and JavaScript implementation. According to the diff of one file in the fix, the debugger formerly used a context_builder.native_context but now it uses a context_builder.evaluation_context. Apparently the native_context created by the old debugger code had trouble resolving (or not treating as read-only) local-scope variables. If you really wanted more, you could contact the author of the fix.
As for why the debugger does not appear in Firefox: it will appear if you are running code from a <script> and have your dev tools open. When running code from the console, it appears that you must have the debugger tab open specifically. Obviously, this is not possible if you have the console open to type in your code, but you can wrap it in setTimeout and quickly switch to the Debugger tab:
setTimeout(function() { debugger; }, 5000)
It is a matter of how the variables are used. Objects are used by reference. So changing a.a will effectively change the value at the proper memory address. Though, changing a itself in any of your test version won't do anything because a new memory address is created for the variable evaluated in the console.
For FireFox not breaking at debugger line, it states in this page (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/debugger) : "If no debugging functionality is available, this statement has no effect.". So, you have to ensure FireBug is installed I presume.

How to edit console using javascript [duplicate]

So apparently because of the recent scams, the developer tools is exploited by people to post spam and even used to "hack" accounts. Facebook has blocked the developer tools, and I can't even use the console.
How did they do that?? One Stack Overflow post claimed that it is not possible, but Facebook has proven them wrong.
Just go to Facebook and open up the developer tools, type one character into the console, and this warning pops up. No matter what you put in, it will not get executed.
How is this possible?
They even blocked auto-complete in the console:
I'm a security engineer at Facebook and this is my fault. We're testing this for some users to see if it can slow down some attacks where users are tricked into pasting (malicious) JavaScript code into the browser console.
Just to be clear: trying to block hackers client-side is a bad idea in general;
this is to protect against a specific social engineering attack.
If you ended up in the test group and are annoyed by this, sorry.
I tried to make the old opt-out page (now help page) as simple as possible while still being scary enough to stop at least some of the victims.
The actual code is pretty similar to #joeldixon66's link; ours is a little more complicated for no good reason.
Chrome wraps all console code in
with ((console && console._commandLineAPI) || {}) {
<code goes here>
}
... so the site redefines console._commandLineAPI to throw:
Object.defineProperty(console, '_commandLineAPI',
{ get : function() { throw 'Nooo!' } })
This is not quite enough (try it!), but that's the
main trick.
Epilogue: The Chrome team decided that defeating the console from user-side JS was a bug and fixed the issue, rendering this technique invalid. Afterwards, additional protection was added to protect users from self-xss.
I located the Facebook's console buster script using Chrome developer tools. Here is the script with minor changes for readability. I have removed the bits that I could not understand:
Object.defineProperty(window, "console", {
value: console,
writable: false,
configurable: false
});
var i = 0;
function showWarningAndThrow() {
if (!i) {
setTimeout(function () {
console.log("%cWarning message", "font: 2em sans-serif; color: yellow; background-color: red;");
}, 1);
i = 1;
}
throw "Console is disabled";
}
var l, n = {
set: function (o) {
l = o;
},
get: function () {
showWarningAndThrow();
return l;
}
};
Object.defineProperty(console, "_commandLineAPI", n);
Object.defineProperty(console, "__commandLineAPI", n);
With this, the console auto-complete fails silently while statements typed in console will fail to execute (the exception will be logged).
References:
Object.defineProperty
Object.getOwnPropertyDescriptor
Chrome's console.log function (for tips on formatting output)
I couldn't get it to trigger that on any page. A more robust version of this would do it:
window.console.log = function(){
console.error('The developer console is temp...');
window.console.log = function() {
return false;
}
}
console.log('test');
To style the output: Colors in JavaScript console
Edit Thinking #joeldixon66 has the right idea: Disable JavaScript execution from console « ::: KSpace :::
Besides redefining console._commandLineAPI,
there are some other ways to break into InjectedScriptHost on WebKit browsers, to prevent or alter the evaluation of expressions entered into the developer's console.
Edit:
Chrome has fixed this in a past release. - which must have been before February 2015, as I created the gist at that time
So here's another possibility. This time we hook in, a level above, directly into InjectedScript rather than InjectedScriptHost as opposed to the prior version.
Which is kind of nice, as you can directly monkey patch InjectedScript._evaluateAndWrap instead of having to rely on InjectedScriptHost.evaluate as that gives you more fine-grained control over what should happen.
Another pretty interesting thing is, that we can intercept the internal result when an expression is evaluated and return that to the user instead of the normal behavior.
Here is the code, that does exactly that, return the internal result when a user evaluates something in the console.
var is;
Object.defineProperty(Object.prototype,"_lastResult",{
get:function(){
return this._lR;
},
set:function(v){
if (typeof this._commandLineAPIImpl=="object") is=this;
this._lR=v;
}
});
setTimeout(function(){
var ev=is._evaluateAndWrap;
is._evaluateAndWrap=function(){
var res=ev.apply(is,arguments);
console.log();
if (arguments[2]==="completion") {
//This is the path you end up when a user types in the console and autocompletion get's evaluated
//Chrome expects a wrapped result to be returned from evaluateAndWrap.
//You can use `ev` to generate an object yourself.
//In case of the autocompletion chrome exptects an wrapped object with the properties that can be autocompleted. e.g.;
//{iGetAutoCompleted: true}
//You would then go and return that object wrapped, like
//return ev.call (is, '', '({test:true})', 'completion', true, false, true);
//Would make `test` pop up for every autocompletion.
//Note that syntax as well as every Object.prototype property get's added to that list later,
//so you won't be able to exclude things like `while` from the autocompletion list,
//unless you wou'd find a way to rewrite the getCompletions function.
//
return res; //Return the autocompletion result. If you want to break that, return nothing or an empty object
} else {
//This is the path where you end up when a user actually presses enter to evaluate an expression.
//In order to return anything as normal evaluation output, you have to return a wrapped object.
//In this case, we want to return the generated remote object.
//Since this is already a wrapped object it would be converted if we directly return it. Hence,
//`return result` would actually replicate the very normal behaviour as the result is converted.
//to output what's actually in the remote object, we have to stringify it and `evaluateAndWrap` that object again.`
//This is quite interesting;
return ev.call (is, null, '(' + JSON.stringify (res) + ')', "console", true, false, true)
}
};
},0);
It's a bit verbose, but I thought I put some comments into it
So normally, if a user, for example, evaluates [1,2,3,4] you'd expect the following output:
After monkeypatching InjectedScript._evaluateAndWrap evaluating the very same expression, gives the following output:
As you see the little-left arrow, indicating output, is still there, but this time we get an object. Where the result of the expression, the array [1,2,3,4] is represented as an object with all its properties described.
I recommend trying to evaluate this and that expression, including those that generate errors. It's quite interesting.
Additionally, take a look at the is - InjectedScriptHost - object. It provides some methods to play with and get a bit of insight into the internals of the inspector.
Of course, you could intercept all that information and still return the original result to the user.
Just replace the return statement in the else path by a console.log (res) following a return res. Then you'd end up with the following.
End of Edit
This is the prior version which was fixed by Google. Hence not a possible way anymore.
One of it is hooking into Function.prototype.call
Chrome evaluates the entered expression by calling its eval function with InjectedScriptHost as thisArg
var result = evalFunction.call(object, expression);
Given this, you can listen for the thisArg of call being evaluate and get a reference to the first argument (InjectedScriptHost)
if (window.URL) {
var ish, _call = Function.prototype.call;
Function.prototype.call = function () { //Could be wrapped in a setter for _commandLineAPI, to redefine only when the user started typing.
if (arguments.length > 0 && this.name === "evaluate" && arguments [0].constructor.name === "InjectedScriptHost") { //If thisArg is the evaluate function and the arg0 is the ISH
ish = arguments[0];
ish.evaluate = function (e) { //Redefine the evaluation behaviour
throw new Error ('Rejected evaluation of: \n\'' + e.split ('\n').slice(1,-1).join ("\n") + '\'');
};
Function.prototype.call = _call; //Reset the Function.prototype.call
return _call.apply(this, arguments);
}
};
}
You could e.g. throw an error, that the evaluation was rejected.
Here is an example where the entered expression gets passed to a CoffeeScript compiler before passing it to the evaluate function.
Netflix also implements this feature
(function() {
try {
var $_console$$ = console;
Object.defineProperty(window, "console", {
get: function() {
if ($_console$$._commandLineAPI)
throw "Sorry, for security reasons, the script console is deactivated on netflix.com";
return $_console$$
},
set: function($val$$) {
$_console$$ = $val$$
}
})
} catch ($ignore$$) {
}
})();
They just override console._commandLineAPI to throw security error.
This is actually possible since Facebook was able to do it.
Well, not the actual web developer tools but the execution of Javascript in console.
See this: How does Facebook disable the browser's integrated Developer Tools?
This really wont do much though since there are other ways to bypass this type of client-side security.
When you say it is client-side, it happens outside the control of the server, so there is not much you can do about it. If you are asking why Facebook still does this, this is not really for security but to protect normal users that do not know javascript from running code (that they don't know how to read) into the console. This is common for sites that promise auto-liker service or other Facebook functionality bots after you do what they ask you to do, where in most cases, they give you a snip of javascript to run in console.
If you don't have as much users as Facebook, then I don't think there's any need to do what Facebook is doing.
Even if you disable Javascript in console, running javascript via address bar is still possible.
and if the browser disables javascript at address bar, (When you paste code to the address bar in Google Chrome, it deletes the phrase 'javascript:') pasting javascript into one of the links via inspect element is still possible.
Inspect the anchor:
Paste code in href:
Bottom line is server-side validation and security should be first, then do client-side after.
Chrome changed a lot since the times facebook could disable console...
As per March 2017 this doesn't work anymore.
Best you can do is disable some of the console functions, example:
if(!window.console) window.console = {};
var methods = ["log", "debug", "warn", "info", "dir", "dirxml", "trace", "profile"];
for(var i=0;i<methods.length;i++){
console[methods[i]] = function(){};
}
My simple way, but it can help for further variations on this subject.
List all methods and alter them to useless.
Object.getOwnPropertyNames(console).filter(function(property) {
return typeof console[property] == 'function';
}).forEach(function (verb) {
console[verb] =function(){return 'Sorry, for security reasons...';};
});
However, a better approach is to disable the developer tool from being opened in any meaningful way
(function() {
'use strict';
Object.getOwnPropertyNames(console).filter(function(property) {
return typeof console[property] == 'function';
}).forEach(function (verb) {
console[verb] =function(){return 'Sorry, for security reasons...';};
});
window.addEventListener('devtools-opened', ()=>{
// do some extra code if needed or ...
// maybe even delete the page, I still like to add redirect just in case
window.location.href+="#";
window.document.head.innerHTML="";
window.document.body.innerHTML="devtools, page is now cleared";
});
window.addEventListener('devtools-closed', ()=>{
// do some extra code if needed
});
let verifyConsole = () => {
var before = new Date().getTime();
debugger;
var after = new Date().getTime();
if (after - before > 100) { // user had to resume the script manually via opened dev tools
window.dispatchEvent(new Event('devtools-opened'));
}else{
window.dispatchEvent(new Event('devtools-closed'));
}
setTimeout(verifyConsole, 100);
}
verifyConsole();
})();
Internally devtools injects an IIFE named getCompletions into the page, called when a key is pressed inside the Devtools console.
Looking at the source of that function, it uses a few global functions which can be overwritten.
By using the Error constructor it's possible to get the call stack, which will include getCompletions when called by Devtools.
Example:
const disableDevtools = callback => {
const original = Object.getPrototypeOf;
Object.getPrototypeOf = (...args) => {
if (Error().stack.includes("getCompletions")) callback();
return original(...args);
};
};
disableDevtools(() => {
console.error("devtools has been disabled");
while (1);
});
an simple solution!
setInterval(()=>console.clear(),1500);
I have a simple way here:
window.console = function () {}
I would go along the way of:
Object.defineProperty(window, 'console', {
get: function() {
},
set: function() {
}
});
In Firefox it dosen't do that, since Firefox is a developer browser, I think since the command WEBGL_debug_renderer_info is deprecated in Firefox and will be removed. Please use RENDERER and the error Referrer Policy: Less restricted policies, including ‘no-referrer-when-downgrade’, ‘origin-when-cross-origin’ and ‘unsafe-url’, will be ignored soon for the cross-site request: https://static.xx.fbcdn.net/rsrc.php/v3/yS/r/XDDAHSZfaR6.js?_nc_x=Ij3Wp8lg5Kz.
This is not a security measure for weak code to be left unattended. Always get a permanent solution to weak code and secure your websites properly before implementing this strategy
The best tool by far according to my knowledge would be to add multiple javascript files that simply changes the integrity of the page back to normal by refreshing or replacing content. Disabling this developer tool would not be the greatest idea since bypassing is always in question since the code is part of the browser and not a server rendering, thus it could be cracked.
Should you have js file one checking for <element> changes on important elements and js file two and js file three checking that this file exists per period you will have full integrity restore on the page within the period.
Lets take an example of the 4 files and show you what I mean.
index.html
<!DOCTYPE html>
<html>
<head id="mainhead">
<script src="ks.js" id="ksjs"></script>
<script src="mainfile.js" id="mainjs"></script>
<link rel="stylesheet" href="style.css" id="style">
<meta id="meta1" name="description" content="Proper mitigation against script kiddies via Javascript" >
</head>
<body>
<h1 id="heading" name="dontdel" value="2">Delete this from console and it will refresh. If you change the name attribute in this it will also refresh. This is mitigating an attack on attribute change via console to exploit vulnerabilities. You can even try and change the value attribute from 2 to anything you like. If This script says it is 2 it should be 2 or it will refresh. </h1>
<h3>Deleting this wont refresh the page due to it having no integrity check on it</h3>
<p>You can also add this type of error checking on meta tags and add one script out of the head tag to check for changes in the head tag. You can add many js files to ensure an attacker cannot delete all in the second it takes to refresh. Be creative and make this your own as your website needs it.
</p>
<p>This is not the end of it since we can still enter any tag to load anything from everywhere (Dependent on headers etc) but we want to prevent the important ones like an override in meta tags that load headers. The console is designed to edit html but that could add potential html that is dangerous. You should not be able to enter any meta tags into this document unless it is as specified by the ks.js file as permissable. <br>This is not only possible with meta tags but you can do this for important tags like input and script. This is not a replacement for headers!!! Add your headers aswell and protect them with this method.</p>

var lastMeta = document.getElementsByTagName("meta")[1];

location.reload();

Now this is just to show it works on all files and tags aswell
#heading {
background-color:red;
}
If you put all these files together and build the example you will see the function of this measure. This will prevent some unforseen injections should you implement it correctly on all important elements in your index file especially when working with PHP.
Why I chose reload instead of change back to normal value per attribute is the fact that some attackers could have another part of the website already configured and ready and it lessens code amount. The reload will remove all the attacker's hard work and he will probably go play somewhere easier.
Another note: This could become a lot of code so keep it clean and make sure to add definitions to where they belong to make edits easy in future. Also set the seconds to your preferred amount as 1 second intervals on large pages could have drastic effects on older computers your visitors might be using

Why does this simple login script work in Tampermonkey but not Greasemonkey?

I have this tiny little script that I run inside Chrome using Tampermonkey and works great.
However, when I use it in Firefox with Greasemonkey, it shows up on the active list, meaning its matching the page but it doesn't actually execute the code. I know it has to be a simple something I am overlooking but its not hitting me.
var myVar=setInterval(function(){myTimer();},100);
function myStopFunction()
{
clearInterval(myVar);
}
function myTimer()
{
var p1 = "Login";
var p2 = "mode=login";
var x = document.body.innerHTML;
if (x.match(p1) && x.match(p2)){
document.documentURI = "/ucp.php?mode=login";
}
myStopFunction();
}
Script Logic/Function
I am using a timer to prevent the script from triggering over and over in a permanent loop.
It simply detects if I am logged into a phpBB forum or not, if not send me to the login page so I can log in.
I am using document URI so that the location of the original is preserved so upon login, it takes me right back to it.
Often phpBB when you log in, it will take you back to the index page so this preserves my original intent of going to the actual link.
This script works perfectly and as expected on Chrome using TM but on Firefox using GM it doesn't trigger, am I missing something here?
From the Firefox spec:
(document.documentURI)
Returns the document location as string. It is read-only per DOM4 specification.
And, indeed, the latest spec still specifies that this attribute must be read only.
If Chrome lets you write this property, then that is non-standard behavior and maybe a bug.
Use location.assign(), or location.replace(), or just programmatically click the login button -- which often preserves the target page.

use of globalstorage is deprecated. please use localstorage instead

I got this message when doing some javascript programming, and after some google searches, I have no idea what it means, or how i cause this error. I'm including the code below, can someone explain it to me or point me to a resource on how to fix it or what is happening at all? The weird thing is that I have other code just like this part in my program, and it never gives me errors about them, so i'm really confused. Also, I only get this error to display with firebug running, else wise it just doesn't work and no error message is displayed. I also tried it in Chrome, and had the same issues, no error message but the code doesn't work.
foundTextFn = function(){
console.log('fire');
if (foundTextArrayPosition != foundTextArray.length){
writeText(foundTextArray[foundTextArrayPosition],"happy");
foundTextArrayPosition += 1;
}
foundTextFnTimer=setTimeout("foundTextFn()",4000);
}
Here is another of my methods, it is basically the same thing, but it works fine. And if it matters, all of these variables are global variables declared at the start of my file as var foundTextArrayPosition = 0; for example.
awayFn = function(){
if (awayArrayPosition != awayArray.length){
if (changeAwayState){
changeAwayState = false;
writeText(awayArray[awayArrayPosition],"normal");
awayArrayPosition ++;
temp = pickRandomSpot();
randomX = temp[0];
randomY = temp[1];
}
else{
changeAwayState = true;
}
awayTimer=setTimeout("awayFn()",10000);
}
else{
abandoned = true;
whyGoneArrayPosition = 0;
whyGoneFn();
}
}
This is a deprecation error in Firefox 9. globalstorage was a way to store data in Firefox, but HTML5 introduced localstorage, which is now the preferred way (using window.localStorage).
https://developer.mozilla.org/en/DOM/Storage has more information.
I got the same error message and found a solution and perhaps the underlying cause of conflict, I was using the jQuery validate function in the jzaefferer.github.com/jquery-validation/jquery.validate.js library along with jQuery 1.7.1
The problem:
I used $(document).ready with two different contexts. One with the noConflict wrapper and one without. By keeping both the same, the error message went away. Hooray!
The wrapper:
jQuery.noConflict();
jQuery(function($) {
$(function() {
$(document).ready(function() { ...}
});
});
See also this post on my blog.
Probably not related to the issue above but I will put it here for the search engines.
I got the same error message while doing some simple jQuery:
Use of globalStorage is deprecated. Please use localStorage instead.
[Break On This Error]
$(document).ready(function() {
It was however due to forgetting to actually include the link href to the jQuery.js file...!

window.open not working in IE

Apparently, this call to window.open is not valid under Internet Explorer. The Javascript code on my site is not running, I would assume it is due to that error.
The line it tells me the error is on, is the call to window.open, apparently an argument is not valid there.
$('.objeto').click(
function() {
var center = 'height=380,width=900,top='+((screen.width - 900)/2)+',left='+((screen.height - 380)/2);
var address = $(this).attr('id');
window.open (address,'Ver articulo', config=center);
}
);
The site runs fine under both Google Chrome, and Firefox.
In IE, you can't have spaces in your second variable (the new window's name).
Try:
window.open (address,'Ver_articulo', config=center);
Also worth re-iterating that IE9 (and possibly below) doesn't like hyphens ('-') in the window name (2nd parameter).
I know one of the comments mentioned this, but it's a bit buried - and it's one tip that just solved an issue for me.
I'm not sure what config is, you just need:
window.open (address,'VerArticulo', center);
Keep in mind though, it looks like your id attribute is invalid to get the effect here, you probably want to use something different, e.g. data-href="urlHere" on the element, if it's not an anchor already.
even thou it's kind a late with answer for OP, but for someone else stumbling across this post it might help:
Had exactly same problem as OP after trying to use "window.open" method. It turns out that Chrome is ok with original href tag with URL in it where IE seems to get confused with that. After removing href from link worked spot on.
CODE SAMPLE:
$(document).ready(function ()
{
$('a[rel^="external"]').each(function ()
{
var externalLink = $(this);
var externalLinkValue = externalLink.attr("href");
externalLink.unbind('click');
externalLink.removeAttr("href");
externalLink.click(function (event)
{
event.preventDefault();
followExtrenalLink = window.open(externalLinkValue,'_blank');
});
externalLink.hover(function ()
{
externalLink.css('cursor', 'pointer');
});
});
