How can I get the value of an input with JavaScript?

Navigation
-2

This is my input and I need to obtain the value by JavaScript of preference that is pure and not with frameworks or if there is no other way or mode. 

<input 
  type="text" class="whsOnd zHQkBf" 
  jsname="YPqjbf" autocomplete="off" 
  tabindex="0" aria-label="Nombre" 
  value="FJ" dir="ltr" data-initial-value="FJ" 
  autofocus="" id="searchInput">

Try this: 

var value = document.getElementById('searchInput').value;

Or with JQuery : 

var bla = $('#searchInput').val();

Greetings.

I made a small code with your input I hope it works for you: 

var boton = document.getElementById("boton");

boton.addEventListener("click", () => {

  var input = document.getElementById("searchInput");
  var valor = input.value;

  alert("El valor del campo es:"+ valor);
  
});
<input type="text" class="whsOnd zHQkBf" jsname="YPqjbf" autocomplete="off" tabindex="0" aria-label="Nombre" value="FJ" dir="ltr" data-initial-value="FJ" autofocus="" id="searchInput">

<button id="boton">Obtner valor</button>
