Best way to remove white spaces from a varied formatted string and convert it to array

I have a search like function that takes in a string. I convert this string to array. The string has comma to distinct between two words.

Ideal format:
search-term-entered = xyz, abc, eee, fff

Now if the user follows my format, I can use split and get my array but what if:

search-term-entered = abc, xyz, , ,,, eee
or search-term-entered = , ,, abc, xyz,eee,fff
or something along these lines

If the user uses some other formatting, how do I get rid of extra white spaces? The only thing is can think of is looping through the array and checking whether for white spaces and removing it. Is there an easier method or way?

This is what my getArray looks like
getArray = search-term-entered.split(", ");

One other way might be

var s = "abc, xyz, , ,,, eee",
    a = s.replace(/(\s*,\s*)+/g,",").split(",");
console.log(a);

", ,, abc, xyz,eee,fff".replace(/[, ]+/g, " ").trim().split(" ")

Something like this.

var str = ', ,, abc, xyz,eee,fff';

function GetFilteredArr(_str) {
  var arr = [];
  var temp = _str.split(',');
  temp.filter(function(v) {
    var _v = v.trim();
    if (_v == "")
      return false;
    arr.push(_v);
  });
  return arr;
}

var filterdArr = GetFilteredArr(str);

console.log(filterdArr);

Simple solution using String.match function:

var str = ', ,, abc, xyz,eee,fff',
    converted = str.match(/\b\w+?\b/g);

console.log(converted);  // ["abc", "xyz", "eee", "fff"]

As noted by @RC, you can find examples of how to filter out null / empty strings on this site already. But to also trim the white space you could use the following.

var s = ', ,, abc, xyz,eee,fff'; 
getArray = s.split(",").map(s => s.trim()).filter(s => s);
