Regular punctuation match punctuation option, but keep punctuation

Question

I have a line of a large paragraph that I am trying to split into sentences using the JavaScript method .split(). I need a regular expression that matches a period or question mark [?.]followed by a space. However, I need to save the period / question mark in the resulting array. How can I do this without positive searches in JS?

Edit: Input "This is sentence 1. This is sentence 2? This is sentence 3." Example: Output Example: ["This is sentence 1.", "This is sentence 2?", "This is sentence 3."]

Answer 2

split(). match()

var text = "This is an example paragragh. Oh and it has a question? Ok it followed by some other random stuff. Bye.";

var matches = text.match(/[\w\s'\";\(\)\,]+(\.|\?)(\s|$)/g);


alert(matches);

:

    Array[4]
        0:"This is an example paragragh. "
        1:"Oh and it has a question? "
        2:"Ok it followed by some other random stuff. "
        4:"Bye. "
