How to get first 2 words?

Question

Let data.title be ABC XYZ PQRS - www.aaa.tld. Output needs to be like this ABC+XYZ

i've tried this:

var t = data.title.split(' ').join('+');
t = t.replace(/(([^\s]+\s\s*){1})(.*)/,"Unknown");
 $("#log").text(t);

Answer 1

Here is one way to do it, no regex though, it only grabs the first two words and must have a space between those words.

First we split into and array, then we slice that array from the 0 index to 2(exclusive) or 1, and finally we join them with a '+':

var x = 'ABC XYZ PQRS';

var y = x.split(' ').slice(0,2).join('+');

// y = "ABC+XYZ"

Try using .match() with RegExp /([\w+]+)/g; concatenate first match, + character, second match

var matches = "ABC XYZ PQRS - www.aaa.tld".match(/([\w+]+)/g);
console.log(matches[0] + "+" + matches[1])
