Remove Non-Numeric Characters from a String in JavaScript

In a non-DOM environment, where you cannot utilize libraries like jQuery, the task of stripping non-numeric characters from a string in JavaScript presents a unique challenge. Here's how you can tackle it:

Utilizing the .replace method, you can employ the D regular expression pattern to match all non-digits. By passing this pattern as the first argument to .replace and an empty string as the second, you can effectively remove all non-numeric characters from the string:

<code class="javascript">myString = myString.replace(/\D/g, '');</code>

For example, if myString holds the value 'abc123.8', this operation would output "1238", retaining only the numeric characters in the string.
