Using Only HTML Form Controls

The following HTML tags have special behavior that when applied within a <form> tag can calculate user data:

<form oninput="out.value = (Math.round(10000*(feet.value / 3.281))/10000)">

  <input id="feet" type="number"> 

  <output id="out" for="feet"></output>


The [for="ID OF INPUT"] attribute of <output> allows it to sync with the value of the <input> (determined by its #ID). The <form> ties in all values in a callback function of an on-event handler registered to an oninput event.


#feet {
  text-align: center;
  width: 8ch
<form id='conv' oninput="out.value = (Math.round(10000*(feet.value / 3.281))/10000)">

  <label for='feet'>Feet: </label>
  <input id='feet' type='number' min='0.000'>

  <label for='meter'>Meter: </label>
  <output id='out' for='feet'></output>


How To Create a Length Converter With HTML and JavaScript, We can develop one JavaScript application to convert any input to feet or in meter. 1 foot = 0.3048 meters 1 meter = 3.2808399 feet. Here is the demo. Input:. A page can't be manipulated safely until the document is "ready." jQuery detects this state of readiness for you. Code included inside $( document ).ready() will only run once the page Document Object Model (DOM) is ready for JavaScript code to execute.

Just wrap it up in a function that waits for the document to be available.

// self executing function here
(function() {
   // your page initialization code here
   // the DOM will be available here

   let number = document.getElementsByClassName('number')[0].innerHTML;
   // do your math here         

Last it would be better to use an ID instead of a classname so you could adress it better.

<p id="number" class="number">12</p>

Solution with an id:

// self executing function here
  (function() {
     // your page initialization code here
     // the DOM will be available here

     let number = document.getElementById('number').innerHTML;
   // do your math here
