I'm trying to use the Salesforce documented method for determining if we're in the Salesforce1 UI when viewing a page in my app but for some reason, this code is not working the browser version of Salesforce (one/one.app)

if( (typeof sforce != 'undefined') && (sforce != null) ) {
    // Salesforce1 navigation

sforce is not defined in /one/one.app ... Any ideas?

  • I assume your running that code in a VF page embedded in S1 right?

  • Also your check is a little off, it should be && sforce.one != null) )

Just guessing by the docs :

Are you trying to run the app in your browser : may be this could be the reason why it is not working


The if statement checks to see if the sforce object is available and usable. This is only true if the page is running inside Salesforce1.

If the sforce object isn’t available, trying to use it to navigate anywhere results in a JavaScript error, and no navigation

  • Salesforce1 is both a browser app (one/one.app) and a native mobile app, so I would expect the Javascript API to be available in both places.

  • that's correct (/one/one.app), the browser container for Salesforce1

The reason why I wasn't able to find sforce in my console was because the Visualforce page is inside of an iframe. I needed to change the context of the console to operate from the frame rather than the top frame in Chrome
