Get element value in JavaScript

The visibility property allows to get an element value. I am sharing a simple code here that shows how easily you can get a element value & text using JavaScript.

Get element value by id

<div><input id="firstname" type="text" value="c-sharphub" /></div>

$(function() {
var firstname = document.getElementById("firstname").value;
  alert(firstname);
});

or
function GetFirstName(){
var firstname = document.getElementById("firstname").value;
  alert(firstname);
}

Get element value by class

<div><input id="firstname" type="text" value="c-sharphub" /></div>

$(function() {
var firstname = document.getElementsByClassName("firstname").value;
  alert(firstname);
});

or
function GetFirstName(){
var firstname = document.getElementsByClassName("firstname").value;
  alert(firstname);
}

Get element text by id

<div><span id="spanText">c-sharphub</span> </div>

$(function() {
  var spanText = document.getElementById("spanText").innerHTML;
  alert(spanText);
});

or
function GetspanText(){
  var spanText = document.getElementById("spanText").innerHTML;
  alert(spanText);
}

Get element text by class

<div><span id="spanText">c-sharphub</span> </div>

$(function() {
  var spanText = document.getElementsByClassName("spanText").innerHTML;
  alert(spanText);
});

or
function GetspanText(){
  var spanText = document.getElementsByClassName("spanText").innerHTML;
  alert(spanText);
}
