Have you ever wanted to rotate through a series of Salesforce dashboards and have them auto refresh? There are multiple questions on the success community and other forums requesting exactly this. The easiest way to rotate through dashboards is to use a browser plugin that switches between pages. However, data in the dashboards can only be scheduled to refresh once per day. A more frequent refresh requires a user to click the refresh button on the dashboard page.
Enter the Tampermonkey browser plugin and a little Javascript. Tampermonkey is a plugin that allows you to execute Javascript code when a page loads in the browser. To solve the problem of getting a refreshed rotation of dashboards, I wrote a little Javascript code that will redirect to a series of dashboard URLs and automatically click the refresh button without user interaction.
