Javascript, jquery: validationg South African ID number and using response

1

I need urgent help with showing a submit button after a jquery validator script ran.

I have a basic form where people insert their South African ID. The script runs and then shows the result in a div. If the ID No is valid, the proceed button must be enabled. If it is not valid, the proceed button must remain disabled.

My form is on codepen:

Many thanks!!!

Ok dont know if i got the time to help get to the answer
But couple of things …
I added this to help me debug and see could i find out how to do what you want

  var _input = $('input');
  _input.keyup(function(){
    debugger;
    validateSubmitButton(checkIDValid())
  })

added it just before the closing bracket of you document ready Function.
so first problem is

function checkIDValid(){
  var answer = document.getElemenstById("id_results").value[0];

getElementsById … should be getElementById … remove the s
secondly .value[0] is wrong

Ok got it working but you might need to tweek it
Just go through the code below and make the changes i made or just copy and paste into pen … just keep a copy of your original in case of error … but working for me

$().ready(function() {
  
$('#idno').rsa_id_validator({
displayValid: [true,"IDNo Valid","IDNo InValid"],
displayDate: [true,""],
displayAge: [true,"AGE:"],
displayGender: [true,"Male","Female"],
displayCitizenship: [true,"Citizenship: South African","Citizenship: Foreign Citizenship"],
});
  var _input = $('input');
  _input.keyup(function(){
    debugger;
    validateSubmitButton(checkIDValid())
  })
});

//no idea what to do here
function checkIDValid(){
  var answer = document.getElementById("id_results");
  if (answer.childNodes[0].data === "IDNo Valid") {
    return true;
  }
}

function validateSubmitButton (checkIDValid) {
  if(checkIDValid == true) {
    $('#valid-button').removeAttr('disabled');
  } else {
    //alert("ID No not correct!")
  }
}
