To match anything other than letter or number you could try this:

<pre><code>[^a-zA-Z0-9]

And to replace:

<pre><code>var str = 'dfj,dsf7lfsd .sdklfj';
str = str.replace(/[^A-Za-z0-9]/g, ' ');

This regular expression matches anything that isn't a letter, digit, or an underscore (<code>_</code>) character.

<pre><code>\W

For example in JavaScript:

<pre><code>"(,,@,£,() asdf 345345".replace(/\W/g, ' '); // Output: " asdf 345345"

You are looking for:

yourVar = yourVar.replace(/[^a-zA-Z0-9]/g, ' ');
</code></pre>

This replaces all non-alphanumeric characters with a space.

The "g" on the end replaces all occurrences.

Instead of specifying a-z (lowercase) and A-Z (uppercase) you can also use the in-case-sensitive option: <code>/[^a-z0-9]/gi</code>.

This is way way too late, but since there is no accepted answer I'd like to provide what I think is the simplest one: \D - matches all non digit characters.

<div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var x = "123 235-25%";
x.replace(/\D/g, '');</code></pre>
</div>
</div>


Results in x: "12323525"

Have you tried <code>str = str.replace(/\W|_/g,'');</code> it will return a string without any character and you can specify if any especial character after the pipe bar <code>|</code> to catch them as well.

<code>var str = "1324567890abc§$)% John Doe #$@'.replace(/\W|_/g, '');</code> it will return <code>str = 1324567890abcJohnDoe</code>

or look for digits and letters and replace them for empty string (""):

<code>var str = "1324567890abc§$)% John Doe #$@".replace(/\w|_/g, '');</code> it will return <code>str = '§$)% #$@';</code>

And to replace:

I'm trying to figure out the regular expression that will match any character that is not a letter or a number. So characters such as (,,@,£,() etc ...

Once found I want to replace it with a blank space.

Any advice.
