HTML5中是否有minlength验证属性？

function minLengthValidator(minLength) {
  return function(input) {
    if (input.length < minLength) {
      return "The input must be at least " + minLength + " characters long.";
    } else {
      return true;
    }
  };
}

<input type="text" id="myInput" placeholder="Enter something..." required>
<div id="error"></div>

document.getElementById("myInput").addEventListener("input", function() {
  var input = document.getElementById("myInput").value;
  var isValid = minLengthValidator(10).call(this, input);
  if (!isValid) {
    document.getElementById("error").innerHTML = "Error: " + isValid;
  } else {
    document.getElementById("error").innerHTML = "";
  }
});
