Validate if the person is of legal age

Navigation

Good afternoon, how do I check if a person is of legal age with the jQuery.validationEngine plugin?

I need the form to only validate if the person is over 18, if it is under 18, it is blocked.

Create a function that will determine your validation: 

function checkIdade(field, rules, i, options){
  if (field.val() < 18) {
     // this allows the use of i18 for the error msgs
     return options.allrules.validate2fields.alertText;
  }
}

Then call your input on class="validate[required,funcCall[checkIdade]]" 

<input class="validate[required,funcCall[checkIdade]]" 
       type="text" 
       id="idade" 
       name="idade" />

funcCall [methodName] 

function checkIdade(field, rules, i, options) {
  if (field.val() < 18) {
    return options.allrules.validate2fields.alertText;
  }
}
$(document).ready(function() {
  $("#form1").validationEngine();
});
