This is my first Answer in stackoverflow and my english is not good. so I can't talk good about this problem:)

I think you might need the following code to get the value of your or tags.

this is what you might need:

HTML

JavaScript

function checkvalue(input , Write) {
  var inputValue = document.getElementById(input).value;
  if(inputValue !="" && inputValue !=null) { 
    document.getElementById(Write).innerHTML = inputValue;
  } else { 
    document.getElementById(Write).innerHTML = "Value is empty";
  }
}

also, you can use other codes or other if in this function like this:

function checkvalue(input , Write) {
  var inputValue = document.getElementById(input).value;
  if(inputValue !="" && inputValue !=null) { 
    document.getElementById(Write).innerHTML = inputValue;
    document.getElementById(Write).style.color = "#000";
  } else {
    document.getElementById(Write).innerHTML = "Value is empty";
  }
}

and you can use this function in your page by events like this:

I hope my code will be useful for you
