I have a client with a Salesforce Community website who wants to have a pop-up on the homepage, but they only want it to pop up one time per user. This is before they login, so I'm thinking what I'd need to do is drop a cookie on their computer so I know that they already saw the pop-up. Is this possible? Does anyone have any better ideas to make this happen? Thanks!

  • once per visit/session? once in a lifetime? – glls Apr 17 at 15:52

Yes, you can use either document.cookie or window.localStorage to remember this sort of information.

Edit: To explain further, you'd create a custom component, and place it within your community somewhere. This component would check to see if the notification has already been displayed (via cookie or a key in storage), and if not, display a modal and set the flag so future visits won't trigger the modal.

  • But how will you access/set these when the Community login page loads? One approach I could think of is to embed a VF page/lightning component on the Community Login page and upon initialization set/access the cookies. Is that what you are recommending? – Jayant Das Apr 17 at 16:26
  • @JayantDas Yes, you'd need a way to display the modal anyways, so a Lightning Component would be ideal here. It can just check if there's a cookie/key, if not, display the message and set the cookie/key. – sfdcfox Apr 17 at 16:48

    Yep I had thought the same, I think it will be good to add that information here in your answer to detail out a bit? – Jayant Das Apr 17 at 16:49
  • @JayantDas Fair enough. Edited. – sfdcfox Apr 17 at 16:55
  • Thanks :) +1 for detailing it out. – Jayant Das Apr 17 at 16:56
