如何通过HTML按钮显示JavaScript功能

Question

I want to display the smallest entered number using HTML button. HTML form gets 3 numbers from user and using JavaScript it displays the smallest number on button click.

<form id="3nr">
  <p><input type="number" placeholder="Numri i pare..."></p>
  <p><input type="number" placeholder="Numri i dyte..."></p>
  <p><input type="number" placeholder="Numri i trete..."></p>
  <p>Numri me i vogel = <output name="min"></output></p>

</form>

        <script type="text/javascript">
    const form = document.querySelector('form')
const inputs = form.querySelectorAll('input[type="number"]')
const out = document.querySelector('output')

form.addEventListener('input', e => {
  out.value = Math.min(...Array.prototype.map.call(inputs, input => input.value))
}, false)
        </script>

Answer 1

Just add a button to your form and attach an event-listener for the click event to it.

 const action = document.getElementById('action'); const form = document.querySelector('form') const inputs = form.querySelectorAll('input[type="number"]'); const out = document.querySelector('output'); action.addEventListener('click', e => { e.preventDefault(); // do not submit the form on click of our button out.value = Math.min(...Array.prototype.map.call(inputs, input => input.value)) }, false) 

 <form id="3nr"> <p><input type="number" placeholder="Numri i pare..."></p> <p><input type="number" placeholder="Numri i dyte..."></p> <p><input type="number" placeholder="Numri i trete..."></p> <p><button id="action">Display</button></p> <p>Numri me i vogel = <output name="min"></output></p> </form>
