I have read that some people download VirtualBox for mac, and use 'localhost' Another way is to copy paste my js code into JSLint and slowly debug any issues that come up in there. What other approaches to people who are developing web applications use for IE?
Are there any other tools? I have the opposite problem as I develop in Windows and need to test Safari on Mac. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. Learn more.
To determine which browser is being used on your computer, see Browsers used by Office Add-ins. In recent versions of Office, one way to identify the webview control that Office is using is through the personality menu on any add-in where it's available. The personality menu is not supported in Outlook.
Open the menu and select Security Info. The runtime isn't included on the dialog in older versions of Office. To install a version of Office that uses the Internet Explorer webview or to force your current version to use Internet Explorer, see Switch to the Internet Explorer 11 webview. Windows 10 and 11 include a web development tool called "F12" because it was originally launched by pressing F12 in Internet Explorer.
F12 is now an independent application used to debug your add-in when it is running in the Internet Explorer webview control, Trident. The application is not available in earlier versions of Windows. If your add-in has an add-in command that executes a function, the function runs in a hidden browser process that the F12 tools cannot detect or attach to, so the technique described in this article cannot be used to debug code in the function.
The following steps are the instructions for debugging your add-in. If you just want to test the F12 tools themselves, see Example add-in to test the F12 tools. Sideload and run the add-in. IEChooser opens with a window named Choose target to debug. Your add-in will appear in the window named by the filename of the add-in's home page.
In the following screenshot, it is Home. Only processes that are running in Internet Explorer, or Trident, appear. The tool cannot attach to processes that are running in other browsers or webviews, including Microsoft Edge. Additionally, Postman has a feature called Collections.
Collections allow you to save sets of requests and responses for your application or for an API. You save valuable time when collaborating with others or repeating the same testing tasks. When using Postman collections, you update the collection if necessary and then use it. This is much faster than repeatedly writing out every test. ESLint is a linter for JavaScript. Linters will analyze code as it is written and identify a variety of basic syntax problems.
The use of ESLint will allow you to catch errors, particularly easy to resolve but annoying ones such as missing brackets or typos, before executing the code. ESLint is available as a Node package. It has also been set up as a plugin for many code editors such as Sublime Text 3 and VS Code, which will then mark the offending errors right in your editor window. It allows you to test and debug scripts right along with other people. You can run the JavaScript, see a debug console and the output of the scripts, add libraries and dependencies, and so much more.
Pro accounts can also take their code private, as well as other benefits. One of the primary reasons you might consider using a tool like JS Bin is simplicity. In JS Bin, you can test the functionality of a small subset of your JavaScript in an isolated environment, without having to set an entire environment for it. You can see your changes in real time. You can copy some code to JS Bin and have a working or not working!
Then you are ready to debug it or share it. It can be incredibly difficult to spot syntax errors or keys which have incorrect values when looking at unformatted JSON. If you have a condensed or minified JSON object, missing line returns, indentations, and spaces, it may be a challenge to read.
You need to be able to quickly scan that object and check for errors in formatting or content. To do that, you will expand the object and format it, wasting valuable time. Postman automatically formats the object and allows you to easily validate both its JSON syntax as well as the actual content.
You simply paste your JSON in, and it outputs the correctly formatted version. The tool will even automatically validate syntax to RFC standards, depending on which you select, if any. The Message part of the Stacktrace is a short overview of what is wrong. In this case, the toUpperCase method is being called on an undefined value.
The Stacktrace tells you where the error occurred and the sequence of function calls that led there. As you can see in the screenshot above, the error happened in the capitalizeString function on line 20 of the index. Knowing which line triggered the error means you can jump straight to the place where the error occurred and start digging into what has caused the problem. The first step is to launch the app in Internet Explorer and open up the Developer Tools. Change to the Console tab by clicking its name.
The Console tab allows you to execute arbitrary JavaScript code at any time or to view any outputs from console. Try entering alert 'Hello! The Console tab is a valuable debugging tool as you can use it as a scratchpad for trying out code and evaluating variables as you diagnose your problem.
To debug the code, you first need to navigate through your source code in the Developer Tools. You do this in the Debugger tab. You can access a tree view of all the source files loaded into the page by clicking the button at the top left of the tab. You can navigate the files here as you would in an IDE, as the contents are displayed in the central pane. If you have a lot of files, you can search them by typing the name of the file into the textbox at the top of the file browser. In the app, you know the problem lies in the index.
Now you can view your code, we want to be able to step through it a line at a time to see where things go wrong.
