STACK OVERFLOW JAVA WEBSCRAPER CODE
There’s no need to copy-paste the code into the post.We decided to implement our own version instead of embedding a third-party site for the reasons mentioned earlier: The normal rules for a link still apply: make sure you copy the relevant code into your question or answer so that it can be accessed if the external site is unavailable. You can still use sites like JSFiddle if you prefer them. JSFiddle and similar sites still have a bunch of features that we have not implemented yet. We don’t have any specific plans at this time to implement other languages, but it’s something we might consider in the future. Server-side languages are much more complicated and require significant infrastructure changes in order to properly implement. These languages also run client-side in the user’s browser, making them self-contained and easy to support. Our initial release supports HTML, CSS, and JavaScript because questions on these topics use external code hosting sites the most frequently. If you see code that is intended to be harmful (such as an attempt at phishing), you should flag it for moderator attention. If you see bad code that you think should be disabled, downvote the post. Because users can still write code that creates annoying behaviors like infinite loops or pop-ups, we disable snippets on any post that is heavily downvoted (scoring less than -3 on Stack Overflow, -8 on Meta). Like all other aspects of our site, Stack Snippets are ultimately governed by the community. We render the Snippets on an external domain ( ) in order to ensure that the same-origin policy is not in effect and to keep the snippets from accessing your logged-in session or cookies.
We use HTML5 sandboxed iframes in order to prevent many forms of malicious attack.We isolate snippets from our sites to block access to your private Stack Exchange data: With that said, the snippets are running client code in your browser, and you should always exercise caution when running code contributed by another user. You are not in any more danger than you are when browsing any site with JavaScript enabled. Yes, as much as the web in general is safe. You can even edit the code right from the Markdown editor and the snippet will still be runnable. The runnable snippets behavior is triggered by a few new HTML comments that are not rendered by Markdown. This makes them instantly backwards-compatible with our normal revision history and diffs, and also any API clients including our own mobile apps. Under the HoodĪ great feature of Stack Snippets is that they are inserted as regular Markdown code blocks: When answering a post containing a snippet, you can easily include a modified version of the original in your answer – just click the “Copy snippet to answer” button. Once you’ve got your code working, press “Insert into Post” at the bottom and you’re done! You can test your snippet, or load it back into the Snippets editor from right in the Preview screen: The editor appears and allows you to enter HTML, CSS, and JavaScript (or any combination of them): In the Markdown editor window, there’s a new button that you can click to launch the Stack Snippets editor. Stack Snippets work for both questions and answers. The code will not run until you press the “Run code snippet ” button: As of today, we’re launching “Stack Snippets,” a fully integrated feature available on Stack Overflow and any other code-related Stack Exchange sites. So we’ve created our own way to embed runnable JavaScript, CSS, and HTML code blocks right in the body of a post. This is an unnecessary burden for both askers and answerers. The community voiced similar concerns around external sites, which eventually led us to block posts that contain links to JSFiddle and similar sites without a corresponding code block. Also, because the code isn’t a part of our post Markdown, changes to it don’t show up in the revision history.

If the code isn’t embedded in the page, visitors are forced to go elsewhere to get the full content of the question or answer.
We’ve always loved JSFiddle and sites like it because they let both askers and answerers reference runnable, working code that demonstrates their problem or solution. On Stack Overflow and our other code-related sites, creating a minimal, complete, and verifiable example is the best way to get an answer to your question.
