Hi everyone,
First of all: I’ve read a lot of other forum threads on this topic and tried out a lot, but I still cannot get any result, so I count on the Bubble-community-wisdom! Hope someone can help me out here …
The facts:
-
My goal is to compare an string to a list of strings from the database and obtain that string that is the most similar to my input-string.
-
I have a Script that I run successfully on different sites where you can try out JavaScripts - it gives me a usable result (e.g. on JSFiddle.net)
-
In Bubble, I to use the Toolbox Plugin with the Action “Run Javascript” - I then have a Javascript To Bubble element on the page, that should return the result in a form that’s usable on Bubble. Only problem: It does not return anything.
-
Here you can see my settings:
The function is as follows:
function myFunction() {
}

I really hope someone can help me out! Maybe someone can find a mistake I’m making?
(Maybe @mishav or @hola1 who were really helpful on a similar thread some years ago?)
I would also be open to try and display the result in an HTML element, but I don’t really get how that’s working. So any suggestions in that regard would also be appreciated!
Thanks!!
