I have 1 lightning community page. In there is a theme layout component. It's just a basic layout wherein the upper 1/4 contains a logo banner and some anchor tags for navigation. Then the lower 3/4 of the layout contains the body. The body contains 1 component for my single page application. To summarize what I currently have:
Lightning community page | -- Theme Layout | -- Upper portion of theme layout | | -- c:banner | | -- c:navbar | -- Lower portion of theme layout | -- c:spa
My problem now is, the
c:navbar component works if it will be used for redirecting to other lightning community pages. But how will I make it send a message to the
c:spa component so that
c:spa can react accordingly?
One of the workarounds I made is to
navigateToURL to the same page and just add parameters to the url every time a link in
c:navbar is clicked, then i'll just let
c:spa process the contents of the URL to know if there is something for it to do. However, doing this refreshes the page and loses the look and feel of a SPA. It also clutters the URL with unnecessary parameters.
Is there any way to send a message from one component to another if they are on separate slots inside a theme layout?
