Determine the maximum and minimum numbers by inputting a number and utilizing jQuery

<script type="text/javascript">
  function findLargestNumber() {
    var number1, number2;
    number1 = Number(document.getElementById("N").value);
    number2 = Number(document.getElementById("M").value);
    if (number1 > number2) {
      window.alert(number1 + " is the larger number");
    } else if (number2 > number1) {
      window.alert(number2 + " is the larger number");
    }
</script>

Answer №1

If my understanding is correct, you are looking to finalize the code above in order for the largest() function to be invoked to determine the largest number between the inputs with id="N" and id="M".

One strategy could involve adding a <button> element and utilizing jQuery to attach a click() handler to it that would execute largest() as shown below:

function largest() {
  var num1, num2;

  /* Updating to utilize jQuery style selectors */
  num1 = Number($("#N").val());
  num2 = Number($("#M").val());

  if (num1 > num2) {
    window.alert(num1 + " from N is the largest, and " + num2 + " from M is the smallest");
  } else if (num2 > num1) {
    window.alert(num2 + " from M is the largest, and " + num1 + " from N is the smallest");
  }
}

/* Getting the find-largest button and attaching a click event listener
that invokes the largest() function */
$("#find-largest").click(function() {

  /* Calling the largest() function */
  largest();

  /* Preventing the default behavior of the button */
  return false;
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.0/jquery.min.js">
</script>
<div>
  <label>Number N:</label>
  <input id="N" type="number" />
</div>
<div>
  <label>Number M:</label>
  <input id="M" type="number" />
</div>

<!-- Add a button that triggers the largest() function when clicked -->
<div>
  <button id="find-largest">Find largest</button>
</div>
