Windows Operations Dashboard comes with a chromium debugger. Follow the tutorial to learn how to debug your extensions.
The debugger tool will display a list of URL(s) for all the extensions used in the operation view.
Note: You can also click on the triangle icon located at the top of your extension's HTML page to open the debug window. Alternatively, click on the widget that you want to debug, and use the Ctrl + Shift + I shortcut keys to open the debug window.
Using the tools inside of the debugger, you can perform a number of debugging activities, such as inspecting UI elements, checking network traffic, loading the extension's source code, and placing break points for further investigation.
Note: If you have questions about the chromium debugger, please contact Esri Support.
You can debug your extension in browser Operations Dashboard just like you would debug any other web application.
Note: IE9 is not supported for debugging using localhost due to its lack of CORS support. Read Set up a web server for more information.
The operation view will load in your default browser where you can use your browser's debug tool to start debugging your extension.
