Ошибка permission denied to access object

just wondering if someone have found seeing the following error in the firebug console, or any idea of what could it mean??
Does this has to do with a browser thing when having the same page opened in two tabs or something??
Have you fixed a similar problem??
What would be a way of ensuring this error is not thrown, is annoying to me :(

Would it have to be with the fact that the site requires cookies, javascript or any considerations you could suggest??

Error: Permission denied to access object

Error: Permission denied to access object

Error:

Error: Permission denied to access object

Error: Permission denied to access object

Error:

Reproducibility:
(6 errors in the console listed when loading a page in two tabs with FF)
Haven’t tried other browsers.. This error appears to be unobtrusive, it does not stop any code from continuing, but I would love to get rid of it, or prevent it.. Thanks in advance for the help!! Much appreciated

Edit:

This is the error mentioned above

And now I get a new one, which might be the cause of the problem :(

Error in Protected Function !281

@Pointy:
— yeah, Tested on FF 18. You are absolutely correct on that statement by the way ;) Thanks for the sanity check :)

The JavaScript exception «Permission denied to access property» occurs when there was an attempt to access an object for which you have no permission.

Message

Error: Permission denied to access property "x"

Error type

Error.

What went wrong?

There was attempt to access an object for which you have no permission. This is likely an <iframe> element loaded from a different domain for which you violated the same-origin policy.

Examples

No permission to access document

<!DOCTYPE html>
<html>
  <head>
    <iframe id="myframe" src="http://www1.w3c-test.org/common/blank.html"></iframe>
    <script>
      onload = function() {
        console.log(frames[0].document);
        // Error: Permission denied to access property "document"
      }
    </script>
  </head>
  <body></body>

As a developer, you may sometimes encounter a «Select permission denied on object» error when trying to access a database. This error occurs when the user does not have the necessary permissions to perform a specific action on the database. This guide will provide you with a step-by-step solution to resolve this error and grant the necessary access to your database.

Step-by-Step Solution

Step 1: Identify the Object and User

The first step in resolving the «Select permission denied on object» error is to identify the object and user that are generating the error. This can be done by looking at the error message and determining the object and user that are mentioned.

Step 2: Grant Permissions

Once you have identified the object and user, you can grant the necessary permissions to resolve the error. This can be done by executing the following command:

GRANT SELECT ON object_name TO user_name;

Replace «object_name» with the name of the object generating the error and «user_name» with the name of the user that needs access.

Step 3: Verify Access

After granting the necessary permissions, you should verify that the user has access to the object. You can do this by executing the following command:

SELECT * FROM object_name;

If the user has been granted the necessary permissions, they should now be able to access the object without receiving the «Select permission denied on object» error.

FAQ

1. What is the «Select permission denied on object» error?

The «Select permission denied on object» error occurs when a user attempts to access a database object without the necessary permissions.

2. How do I identify the object and user generating the error?

You can identify the object and user by looking at the error message that is generated.

3. How do I grant permissions to resolve the error?

You can grant permissions by executing the following command:

GRANT SELECT ON object_name TO user_name;

4. How do I verify that the user has access to the object?

You can verify access by executing the following command:

SELECT * FROM object_name;

5. Can I grant other types of permissions besides «Select»?

Yes, you can grant other types of permissions such as «Insert», «Update», and «Delete».

As we continue through our JavaScript Error Handling series, we’ll take a closer look at one of the most basic JS errors, the Permission Denied error.

As we continue through our in-depth JavaScript Error Handling series, we’ll take a closer look at one of the most basic errors in JavaScript, the Permission Denied error.

Below we’ll examine what exactly causes a Permission Denied error in JavaScript, and how to both handle and avoid this error in your own projects, so let’s get started!

The Technical Rundown

  • All JavaScript error objects are descendants of the Error object, or an inherited object therein.
  • While the Permission Denied error we’re examining here is a base Error object, the Error object itself can be used and extended for custom error constructors.

When Should You Use It?

Since the Permission Denied error does not have an explicit inherited constructor associated with it below the baseline Error object itself, it can be difficult to accurately determine when this particular error has reared its ugly head purely within the standard try-catch syntax of JavaScript.

That said, we’ll begin examining the Permission Denied error with a simple example. This error most commonly appears when JavaScript attempts to access an object for which it has no permission, such as an <iframe> element that is attempting to load content from another domain.

For this simple example, our HTML contains a simple <iframe> with src property that violates the same-origin policy:

&lt;iframe id="myframe" src="https://en.wikipedia.org"&gt;&lt;/iframe&gt;

Our JavaScript contains a simple printError() function which assists with formatting the output of a passed in error, telling us the error type, the error message, and allowing us to specify if the error was explicitly provided.

Additionally, we have a simple try-catch clause after attempting to access and output the first (and only) frame in our document, the above <iframe>:

function printError(error, explicit) {

    console.log(`[${explicit ? 'EXPLICIT' : 'INEXPLICIT'}] ${error.name}: ${error.message}`);

}

try {

    console.log(frames[0].document);

} catch (e) {

    if (e instanceof Error) {

        printError(e, true);

    } else {

        printError(e, false);

    }

}

The expected output is an EXPLICIT Permission Denied error, and sure enough that’s what we see:

[EXPLICIT] Error: Permission denied to access property "document"

Since we are explicitly checking for our e error object to be an instanceof the Error object, it is expected that this is caught and sent to our printError() function as an EXPLICIT object reference. If we change this so that our catch clause doesn’t check for any explicit instanceof Error, the same error would be produced, but it would be INEXPLICIT by our own measurement:

function printError(error, explicit) {

    console.log(`[${explicit ? 'EXPLICIT' : 'INEXPLICIT'}] ${error.name}: ${error.message}`);

}

try {

    console.log(frames[0].document);

} catch (e) {

    printError(e, false);

}
[INEXPLICIT] Error: Permission denied to access property "document"

The real problem with trying to capture the Permission Denied error comes about when we recognize that simply catching an instanceof the base Error object isn’t enough, as this will catch all sorts of other errors that are unrelated.

For example, let’s change our code a little bit to execute a recursion loop and trigger an InternalError: Too much recursion:

function printError(error, explicit) {

    console.log(`[${explicit ? 'EXPLICIT' : 'INEXPLICIT'}] ${error.name}: ${error.message}`);

}

function repeat() {

  repeat();

}


try {

    repeat();

} catch (e) {

    if (e instanceof Error) {

        printError(e, true);

    } else {

        printError(e, false);

    }

}

Upon execution of our new code where we call the repeat() function, which recursively calls itself ad infinitum, we get the following output:

[EXPLICIT] InternalError: too much recursion

JavaScript has assumed that our explicit check for our error to be an instanceof Error is what we wanted, even though the actual error object that was caught was InternalError.

As you might imagine, the problem here is that InternalError (along with virtually all other error objects), is a descendant of the Error object, so capturing Error captures everything.

Therefore, in order to properly capture only the Permission Denied error, we need additional logic within our catchclause. Since using the name property for our error does us no good, the only other standard property to the Errorprototype that’s available is message, so we’ll need to parse that to verify we’re getting the Permission Denied error and not something else:

function printError(error, explicit) {

    console.log(`[${explicit ? 'EXPLICIT' : 'INEXPLICIT'}] ${error.name}: ${error.message}`);

}

try {

    console.log(frames[0].document);

} catch (e) {

    if (e.message.toLowerCase().indexOf('permission denied') == 0) {

        printError(e, true);

    } else {

        printError(e, false);

    }

}

While this is perhaps not the most efficient method, above we’re simply checking whether our Error object message property text contains the phrase permission denied at the beginning, and if so, we can consider that the EXPLICIT error we’re looking for.

The output is as expected:

<code>[EXPLICIT] Error: Permission denied to access property "document"</code>
