I'm not sure if you want all white spaces removed or to have words separated by 1 space. Below are 2 examples. And yes, I don't like RegEx, but was doing something similar the other day.

An example with no white space.

JavaScript

var name = "this is the test       case";
name = name.replace(/\s/g, '');
document.getElementById("test1").innerHTML = name;

An example with 1 space between words.

JavaScript

var name = "this is the test       case";
name = name.replace(/\s+/g, ' ').trim();
document.getElementById("test2").innerHTML = name;

Test in HTML.

HTML

<div id="test1"></div>
<div id="test2"></div>

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx: Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx: Regexper[^]
