Set Last Six Digit Regex Patterns for HTML5 Text field

The validation I need for regex is to check only if the input has last six digit on the input.
Sample Accepted Input name are as follows:

• Juan Dela Cruz 123456
• Juan Dela Cruz | 123456

<form action="/action_page.php">
  <label for="employee">Employee Name:</label>
  <input type="text" id="employee" name="employee" pattern="([0-9]{6})$" title="Last Six Number"><br><br>
  <input type="submit">
</form>

>Solution :

Try using this pattern instead:

.*([0-9]{6})$

That way, the entire value (including anything before the digits) matches. .* in RegEx matches anything.

  <input
    type="text"
    id="employee"
    name="employee"
    pattern=".*([0-9]{6})$"
    title="Last Six Number"
  >
