I have an input field:

<input name="onkirmizi[]" type="text" class="form-control" tabindex="1" >

And I want to give this input field validation which only allows 2 characters allowed. So in this point, I have two questions.

  1. Do I need to put it inside of the form?
  2. Do I need to add js file (if so how can I do that)?

Attribute maxlength

Accepts a positive integer

When this number is reached during dialing, no further input is possible.

<!DOCTYPE HTML>
<html>
 <head>
  <meta charset="utf-8">
  <title>Tag INPUT, attr maxlength</title>
 </head>
 <body>

  <form  action="handler.php">
   <p><input type="text" maxlength="2"></p>
   <p><input type="submit" name="submit" value="Submit"></p>
  </form> 

 </body>
</html>
