A similar question has been asked many other times, I'm aware, but my case is rather specific and has, to my knowledge, never been touched on before. At least from what I can find.
What I'm doing is building objects using a UID. Everything that the object is built with requires this UID and it requires it to be verified as unique before anything can be done with it.
I'm randomly generating the UID in javascript and I'm checking it against all other entries in a SQL database. I'm posting to the database using PHP and Ajax.
The core issue I'm having is that Javascript doesn't wait for the Ajax response and instead just keeps rolling. Ajax has to use a success handler. This is strictly not possible for me to use because I cannot do anything until I know for certain that the UID is verified.
Are there any workarounds or solutions to this? Promises won't work because, as I stated before, the UID is integral in building the object in and of itself, so using placeholders won't work.
Thanks in advance!
