Issue Details

I want to use LabVIEW Remote Front Panels so that I can create a VI in LabVIEW and interact with it through a web browser.  However, the technologies required to use LabVIEW Remote Front Panel, Netscape Plugin Application Programming Interface (NPAPI), requires me to use Internet Explorer as the plugin support has been dropped from other browsers.  I want to be able to use other browsers besides Internet Explorer to interact with my VI in the web.  What are my options?

Solution

LabVIEW NXG WebVIs let you create a web-based UI within the LabVIEW NXG editor.  WebVIs are built on the standard web browser technologies such as HTML5, Javascript, and CSS.  So, WebVIs are able to be deployed and then accessed from any web browser that supports HTML5, Javascript, and CSS.  No additional plug-ins such as NPAPI are necessary to interface with WebVIs.

You could also create the web front end from scratch (what is done for you in LabVIEW WebVIs) if you are comfortable working with HTML, Javascript, and CSS.  It may be worth looking at the Getting Started Series | Simple JavaScript and HTML with LabVIEW Web Services to get a feel for what is required to tie things together if you decide to go this route. 

Additional Information

WebVIs are included in the LabVIEW NXG Web Module, which also supplies the Skyline API that allows for easier data communications between your WebVI and other parts of your application.
