how we can correct pattern for digits only

Question

In this field we can enter only digits

my code is

<input name="issue_bal" id="issue_bal" 
 type="text" required="required" 
 pattern="[0-9]" tabindex="1" 
 class="limiter mid"/>

but this is not working.

Answer 1

Your pattern only describes 1 digit, not multiple. In order to validate 1 or more digits use the following pattern:

pattern="[0-9]+"
