Javascript app-cache to service worker conversion

Hello developers, We have a browser web app called PDQ - [login to view URL] that needs a small update. If you have done this app-cache to service worker type project before please respond. 1) Convert an existing and working [login to view URL] app from app-cache to server workers. We will need a trigger to force a product update like app-cache does. We run this app on IOS Safari / Android Chrome / Windows Chrome and it will still need to run on these platforms after implementing the Service Worker. 2) Fix a broken jquery switch event. It is only broken on Chrome in Windows (works fine on IOS and Android and Windows 10 with touch screen). Something to do with the mouse event (see below).

This new third choice will be disabled unless a very current date / time stamp is detected. It will run the exact same code as the second choice "Patient Profile Table". I will provide more details on this time stamp later. [login to view URL] 4) Add one new button to launch DropBox in a new browser tab with a lookup parameter to filter documents. Item #1 is the main concern. Please only respond if you are familiar with converting app-cache to Service Workers. Example projects and guides: [login to view URL] [login to view URL] I will provide a remote log in to a windows 10 PC with all the JavaScript, HTML and other files with the current working app and for you to show the success of your work on the project. The PDQ app works with our own web page server that will be installed on the Windows 10 PC as well. The scope of the project is 1-4 above. I'm a Windows developer and I'm responsible for the web page server part that I wrote in Delphi. Craig Oberfield Quick Notes [login to view URL]
