Nested string functions


I’m trying to build - what I think is - a complex string function and I’m strugging.

From a string, I want to cut out a part of it in the middle.

What I would like to do is something like this:

originalString = “Apple, Banana, Pear, Peach”;
toRemove = “Banana”;
start = originalString.indexOf(toRemove);
left = originalString.slice(0, start);
right = originalString.slice(start + toRemove.length);
result = left.concat(right);

Let’s say, I want this to work on the click of a button, which updates the text on a box.

In Interactions I use: OnClick -> setText

And I’m stuck. There’s only one field there. Of course, all of this can be combined into one complex phrase:

[[originalString.slice(0, originalString.indexOf(toRemove)).contact(originalString.slice(originalString.indexOf(toRemove) + toRemove.length))]]

The problem is, that this is not working.

Please check the uploaded file and let me know what am I doing wrong?

You misspelled concat as contact so I’d try correcting that first and see if it works.

That said, it might be easier to just use replace:


You could also add .replace(',,',',') in case you end up with a double comma from removing something in the middle of the list.
