Checking permissions in Javascript

[Lior Hadaya, modificado 11 Anos atrás.]

Hi,

I'm using Liferay EE 6.1.20.
I know it's easy to check if the logged in user has edit permission on a page in Java code, like this:

boolean can_update = LayoutPermissionUtil.contains(themeDisplay.getPermissionChecker(), layout, ActionKeys.UPDATE);

My question is - can I do the same using Liferay's Javascript API?
I found this method: Liferay.Service.Portal.Permission.checkPermission(params, callback)
inside the Liferay Javascript object, but haven't been able to figure out how to use it.

Any help would be greatly appreciated!

Thanks,

Lior
