It seems the minlength attribute for an <input> field doesn't work.

Is there any other attribute in HTML5 with the help of which I can set the minimal length of a value for fields?


You can use the pattern attribute. The required attribute is also needed, otherwise an input field with an empty value will be excluded from constraint validation.

<input pattern=".{3,}"   required title="3 characters minimum">
<input pattern=".{5,10}" required title="5 to 10 characters">

If you want to create the option to use the pattern for "empty, or minimum length", you could do the following:

<input pattern=".{0}|.{5,10}" required title="Either 0 OR (5 to 10 chars)">
<input pattern=".{0}|.{8,}"   required title="Either 0 OR (8 chars minimum)">

HTML 5 input now supports minlength validation using pattern attribute.


There is a minlength property in HTML5 spec now, as well as the validity.tooShort interface.

Both are now enabled in recent versions of all modern browsers. For details, see https://caniuse.com/#search=minlength.

jQuery.validator.setDefaults({
    debug: true,
    success: "valid"
});;
</script>

  <script>
  $(document).ready(function(){
    $("#myform").validate({
  rules: {
    field: {
      required: true,
      minlength: 3
    }
  }
});
  });
