JavaScript split String with white space

Question

I would like to split a String but I would like to keep white space like:

var str = "my car is red";  var stringArray [];  stringArray [0] = "my"; stringArray [1] = " "; stringArray [2] = "car"; stringArray [3] = " "; stringArray [4] = "is"; stringArray [5] = " "; stringArray [6] = "red"; 

How I can proceed to do that?

Thanks !

Answer 1

Using regex:

var str   = "my car is red"; var stringArray = str.split(/(\s+)/);  console.log(stringArray); // ["my", " ", "car", " ", "is", " ", "red"]  

\s matches any character that is a whitespace, adding the plus makes it greedy, matching a group starting with characters and ending with whitespace, and the next group starts when there is a character after the whitespace etc.

Answer 2

You could split the string on the whitespace and then re-add it, since you know its in between every one of the entries.

var string = "text to split";     string = string.split(" "); var stringArray = new Array(); for(var i =0; i < string.length; i++){     stringArray.push(string[i]);     if(i != string.length-1){         stringArray.push(" ");     } } 

Update: Removed trailing space.
