Hello everybody, Im working on a project and I want that when clicked on the "national" checkbox the country div shows and the europe div hides and when clicked on the international happens the other way around. In my effort of achieving this, Ive wrote this code, though it doesnt work. Can anybody tell me what did I do wrong or how should I pursue this?

<div><div><form id= "form1">
<input type="checkbox" name="option3" value="national" id= 'national' onchange= "f()"> National</input>
<input type="checkbox" name="option4" value="internacional" id= 'inter' onchange= "f()"> International</input>
<input type="button" value="check" onclick="f()">
<script type= "text/javascript">

var nation= document.getElementById("national");
var international= document.getElementById("inter");

var country= document.getElementById("country");
var europe= document.getElementById("europe");

function f()
if (nation.checked= true) &&(international.checked= false)
{ country.style.display='block';
europe.style.display='none'; }
else if (nation.checked= true) &&(international.checked= false)
{ country.style.display='none';
europe.style.display='block'; }
else if (international.checked= true) &&(nation.checked= true)
{ country.style.display='none';
alert("Dont select both at the same time.")}

{ peru.style.display='none';
europe.style.display='none'; }}

<!--This div only appears if national its selected
<div id= 'country'>
<form id= 'regiones'method= 'POST'>
<select id= 'selection'>Uno

<!-- This div only appears if international its selected
<div id= "europe">
<form id= 'Europea'method= 'POST'>One
<select id= 'sel1'>
</div> </div>

if (nation.checked= true)

You're not checking if it equals true. You set it to true there.

To check if it equals you need 2 or 3(more strict) equal signs.

Or in case of true/false:

  • 0

Also tagged with one or more of these keywords: checkbox, div, hide, show, hide element, show element, hide div, show div, checkbox.checked
