![]() On Node.js, notebook.js runs all HTML and Markdown outputs through DOMPurify. To support other Markdown or ANSI-coloring engines, set nb.markdown and/or nb.ansi to functions that accept raw text and return rendered text. The browser-based version does not, however, ship with those libraries, so you must -include or require them before initializing notebook.js. On Node.js, notebook.js uses marked for Markdown rendering, and ansi_up for ANSI-coloring. readFileSync ( "path/to/notebook.ipynb" ) ) var notebook = nb. Final Thoughtsįor instance: document.Var fs = require ( "fs" ) var nb = require ( "notebookjs" ) var ipynb = JSON. You can also add an event listener to wait for the page to load completely. #Inject html and js in inotebook codeNow the code waits 10 seconds before it executes, and voilà it works perfectly. SetCssStyle(element, "display", "none !important") But for time-saving measures, we are going to try adding a timeout function to our original snippet to see if that helps. We could dig in the network log to see if that’s the case. One of the reasons could be that the iframe loads after X seconds of the page loading. The Injection Code Didn't Work, What Now?Īfter testing it, the iframe didn’t disappear as it did when we tested it in the console. Screenshot showing The Washington Post’s website with an article mentioning Andrew Yang, also Chrome’s developer tools. The page will immediately reload to try and test your added code. To add it, left-click on the extension icon on your address bar and add the custom snippet, then click save. Now it's time to add it to the extension, custom JavaScript for websites, and test if the code will work on future visits. Test your code in the Chrome developers’ console to make sure that it works. SetCssStyle(element, "display","none !important") Īs you can see, in the code above we are highlighting the element wallIframe and hiding it by adding inline CSS. Var element = document.getElementById("wallIframe") Idx = result.index + result.indexOf(result) Įl.style.cssText = el.(0, idx) +Įl.(idx + result.length) Įl.style.cssText += " " + style + ": " + value + " " #Inject html and js in inotebook update* If you want to update / add single style in DOM Element style attribute you can use this function: Now, we’ll be using a small JavaScript snippet to add custom CSS and check if we can hide the pop-up. In this example, the iframe element with ID wallIframe contains the pop-up with some fading background in the back. Open your Chrome developer tools by pressing F12, then identify the element with the pop-up. Locating DOM Elements and Creating the Injection Code For this tutorial, I am using The Washington Post’s website: Screenshot showing The Washington Post’s website with an article mentioning Andrew Yang, also Chrome’s developer tools. This small extension allows you to run JavaScript on any website automatically, and it saves the code for future visits in your web browser.įirst, visit the website with annoying pop-ups that you use often. Install the extension custom JavaScript for websites. The following only applies if you use Google Chrome. Installing the Extension to Inject the Code We'll go through to the process step by step in this small guide. Many times, we use those websites daily for all kinds of things, and seeing those pop-ups over and over gets old!ĭevelopers can get around these by going to the console and finding selectors to manipulate the website's document object model (DOM) by adding or modifying CSS or JavaScript.īut now, thanks to Google Chrome and its extension store, anyone can inject code into any website automatically. As developers and users of the internet, we often come across websites that display many pop-ups, from subscription requests to paywalls, advertisements to notifications, and so on. ![]()
