The policy is enforced in all relevant browsers , including all versions of Chrome, Firefox, Safari, Opera, and Internet Explorer. Whenever an error is emitted from Angular, the error will be recorded as simply Script Error with no mention of the original message, the angular.
Consider how Chrome exposes a JavaScript Error. When an error occurs, it evaluates the security origin of the file. If it violates the policy, the error is simply overwritten with empty values. Therefore, you may not be aware that errors are being obfuscated until you begin monitoring them. It can also be used to load JavaScript assets exempt from error obfuscation. Open the Run dialog box by pressing the Windows Key and then the R key.
Enter the inetcpl. Open the tab called Advanced. Scroll down until you find the Browsing section, and then look for these three settings:.
Press OK to save the changes. Turning off scripting errors will stop you from seeing them but doesn't necessarily mean that the scripts themselves will work properly just because their related errors are no longer seen. Certain security settings in IE will prevent ActiveX and Java from running properly, which can affect the usability of the web page that's running the script. The quickest way to get these features working again if they aren't already is to reset the security settings in Internet Explorer.
Temporary files are cached on your computer by Internet Explorer so that you can revisit websites quicker, but a cache that's too large or one that's storing corrupted data can result in script errors.
You should periodically delete these cache files. A pop-up blocker is extremely useful most of the time, but might actually be causing script errors if the script isn't given enough time to run because the browser is preventing pop-ups. All web browsers let you control the pop-up blocker settings. If you disable the blocker, then pop-ups will be allowed to run again. Outdated software might be what's causing the specific script error that you're seeing.
This might be because the website or program showing the error, has a minimum requirement that your computer doesn't meet, or because a script error was corrected through an update that you never received. You should always keep Windows up to date. You should update your third-party programs if they're getting script errors. A free software updater tool is one easy way to do this. It's possible that your antivirus program or firewall application is blocking scripts or ActiveX controls from running normally.
Temporarily disable both to see if you still get the script error. You should never leave your computer open to attacks, but in this case, the security software might be to blame, so temporarily disabling them just for a few minutes won't do any harm.
The procedure is different for every program but you should be able to right-click the software running on the Windows taskbar, next to the clock, to turn off the AV shields or disable the firewall.
If not, try opening the program — there's most definitely an option there to disable the application. Particular to this problem, CDNs use the massive resources of public clouds to keep both costs and response times low. When your web application code is defined and loaded to a script hosted on a different domain to the one in the address bar, errors that hit the window.
This is most obvious when Raygun4JS reports these errors, and the error groups lack any indication as to what happened. The specification and implementation for controlling the same-origin policy is documented nicely here.
See different browser behaviors in detail at the end of the article. There are two critical pieces of metadata to include to allow a cross-domain script to pass the CORS validation in a modern browser.
You need to use the first one on the script tag you add to the HTML on the origin domain and the second one on the HTTP response sent by the third-party domain. As the above documentation lists, you need to use the crossorigin attribute on the appropriate script tag. By example:. However, when they recognize that the script is requested from a third-party domain, your browser will refuse to load it.
Thus, there is no exchange of user credentials via cookies or HTTP authentication when the request is sent back and forth. The second critical bit of data is the presence of an HTTP header on the response from the third-party domain containing the JavaScript. In particular, the Access-Control-Allow-Origin header:. The wildcard in this example allows cross-site requests to any site.
This is appropriate for a CDN where the script may be requested by any third-party domain. If this is a private host for a known set of domains, you can provide that list in place of the wildcard, for instance:. Contact the administrator of the web server if you suspect that a problem affects a server-side script.
These methods listed in this article may help you troubleshoot the script errors that are caused by files or settings on your computer.
For quick visual instructions about how to troubleshoot script errors in Internet Explorer, watch this video:. Microsoft encourages you update your system with the latest windows update available. If the only sign of this problem is the error message, and the websites are working, you can probably ignore the error. Also, if the problem occurs on one or two webpages, the problem may be caused by those pages. If you decide to ignore the errors, you can disable script debugging.
To narrow down the source of the problem, use another user account, another browser, or another computer to view the webpages that triggered the script error. If the script error doesn't occur when you view the webpage through another user account, in another browser, or on another computer, the problem may be caused by files or settings on your computer.
In this situation, follow the methods in this article to resolve this problem:. After you complete each method, try to open a webpage on which you previously received a scripting error. If you don't receive the error, the problem is resolved.
Active scripting, ActiveX, and Java are all involved in shaping the way that information is displayed on a webpage. If these features are blocked on your computer, it may disrupt the display of the webpage. You can reset your Internet Explorer security settings to make sure these features aren't blocked. To do it, follow these steps:.
On the Tools menu, select Internet Options.
