Javascript Regex Split After Certain Word or Number

Question

The regex:

"12 DOse Flaschentomaten".split(/(\d+(?:\s(?:Dose|TL|EL)){0,})\s+(.*)/gi)

Gives me in the regex tool (https://www.regex101.com/) two groups:

12 DOse  
Flaschentomaten

Which is what I want.

But in the javascript console this array

["", "12 DOse", "Flaschentomaten", ""]

Side Questions: If I want to use an external array for the filter words do I have to define it as a string: var filterWords = "sp, ts, spoon"; Can I use the i tag for not case sensitive also only on groups?

What is the "main" question ? if you're asking why you get this result, it's because you are splitting your string I guess, regex101 only get the matches of your regex — Hacketo

what's the issue you've hit here? is the question how to get your array of results into a string? — atmd

The issue/main question is how to split phrases like 1 Dose Banana, 1 Banana or 1 TL Banana into two strings. The first should contain the 1 + an optional Word the second should contain the rest (in the example Banana). Unfortunately my regex seems to split the phrase into 4 pieces. — Andi Giga

I could use array.shift() and array.pop() afterwards but why does it add the empty strings in the first place/ and how to avoid that? — Andi Giga

I guess you want match, not split:

m = "12 DOse Flaschentomaten".match(/(\d+(?:\s(?:Dose|TL|EL))?)\s+(.*)/i)
document.write("<pre>" + JSON.stringify(m,0,3));

Add m.shift() to remove the first element (=the whole match).
