regex - HTML5 form validation pattern alphanumeric with spaces?

Question

I have the following input tag in my html5 form:

<p>
    <label>Company Name*</label>
    <input type="text" name="name" class="field" required pattern="[a-zA-Z0-9]+" />
</p>

This works just fine checking if the company name consists out of alphanumeric characters. But of course I want to allow spaces in the company name. I need to know what I should add to the pattern.

Answer 1

How about adding a space in the pattern attribute like pattern="[a-zA-Z0-9 ]+". If you want to support any kind of space try pattern="[a-zA-Z0-9s]+"
