Javascript Regex everything before a space and including the space-CodePudding

I need to remove all text before a space and the space itself from a list of strings. For example, John Doe needs to be just Doe. How could I do that?

CodePudding user response：

Does it have to be regex? As an option; if you need everything after the space, you can just use split and then pop to get the last item.

var str = 'John Doe';
var final = str.split(' ').pop();
console.log(final);

Here is a solution using a list of string, as you mentioned:

var strList = ['John Doe', 'Jane Smith', 'Stack Overflow'];

for (var i = 0; i < strList.length; i  )
{
  var final = strList[i].split(' ').pop();
  console.log(final);
}

This pattern would work, but it would only work for first space

[^\s]*\s

Usage : str.replace(/[^\s]*\s/,"")

If you want to support something like "John Doe" Then this pattern would work [^\s]*\s

console.log("John Doe".replace(/[^\s]*\s/,"")) //only one first space
console.log("John        Doe".replace(/[^\s]*\s /,"")) //many spaces
