In JavaScript/regex, how do you remove double spaces inside a string?

Question

If I have a string with multiple spaces between words:

Be an      excellent     person

using JavaScript/regex, how do I remove extraneous internal spaces so that it becomes:

Be an excellent person

Answer 1

You can use the regex /\\s{2,}/g :

var s = "Be an      excellent     person"
s.replace(/\s{2,}/g, ' ');

Answer 2

This regex should solve the problem:

var t = 'Be an      excellent     person'; 
t.replace(/ {2,}/g, ' ');
// Output: "Be an excellent person"

Answer 3

Something like this should be able to do it.

 var text = 'Be an      excellent     person';
 alert(text.replace(/\s\s+/g, ' '));

Answer 4

you can remove double spaces with the following :

 var text = 'Be an      excellent     person';
 alert(text.replace(/\s\s+/g, ' '));

Snippet:

  var text = 'Be an excellent person'; //Split the string by spaces and convert into array text = text.split(" "); // Remove the empty elements from the array text = text.filter(function(item){return item;}); // Join the array with delimeter space text = text.join(" "); // Final result testing alert(text);
