[Solved] Need help Javascript validation input text and date [closed]

by 


function validate() {
  //Make a selector pointing to your input first
  var myInput = document.getElementById('yourInputId').value

  //Validate length:
  if (myInput.length >= 8) {
  //Check for age 
  if (eval(myInput) >= 16) {
  alert('your input is ok!');

  }
  else {
  alert('Minimum age is 16!');
  }
  }
  else {
  alert('input too short!');
  }
}

P.S.: For character exclusion you should jump into Regular Expressions

(Tons of example on the web, just Google it!)
