I need to remove the HTML tags from a variable, or do not interpret the HTML of this variable. The problem is that the variable has its value coming from an input, so:

var msg = $('input').val();

As there is no way to get the .text () from the input, I do not know how to remove or at least not interpret the HTML tags there! Any help?

When we put a string in html format inside a jquery $ () selector, jquery turns that string into an object that can be manipulated by jquery itself, and then you can extract the text.

var msg = $('input').val(); // output -> <div>Ola</div>
var textoExtraido = $(msg).text() == "" ? msg : $(msg).text(); // output -> Ola

Since you're using jQuery, you can treat the field like this:

var msg = $('input').val();

//retira as tags
$('<p/>').html(msg).text();

//faz encode das tags
$('<p/>').text(msg).html();

Here's an example:

function f() {

var msg = $('input').val();

var opcao1 = $('<p/>').html(msg).text();

var opcao2 = $('<p/>').text(msg).html();

$('input[name="opcao1"]').val(opcao1);

$('input[name="opcao2"]').val(opcao2);

};

$('input').keyup(function() { f(); });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><inputplaceholder="Digite o texto" type="text" /><br />
<p>Opção 1 (removendo tags)</p>
<input name="opcao1" type="text" />
<p>Opção 2 (encode tags)</p>
<input name="opcao2" type="text" />

Focus on the next input when reaching the maximum number of characters "The process can not access the file because it is being used by another process"

If you want to keep the tags unread, you can replace < and > with your HTML entity < and > respectively. The result the browser will interpret as a common text:

var msg = $('input').val();
msg = msg.replace(/</g, '&lt;').replace(/>/g, '&gt;');
$("body").append(msg);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><inputvalue="<b>abc</b>">

Removing tags with .replace and regular expression

var msg = $('input').val();
msg = msg.replace(/<.+?>/g, '');
console.log(msg)

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><inputvalue="<i class='classe'>abc1</i> <b>def2</b>">

The expression <.+?> captures everything that is <nome da tag, atributos, fechamento etc.> and .replace removes the string.
