Is there a minlength validation attribute in HTML?

html, validation

Solution

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)">

Problem

It seems the `minlength` attribute for an `<input>` field doesn't work. Is there any other attribute in HTML with the help of which I can set the minimal length of a value for fields?
