good! I'm pretty new with javascript and I'm having a serious problem validating and redirecting the input. This is my html code:

<div class="grid-container">
    <a href="index.html" class="back"><span></span> < </a>
</div>

<div class="flex-container-registro">
    <div class="cuadroAzul">
        <p>REGISTRATE<br/>
        Ahora crea tu codigo de seguridad</p>
    </div>

    <form class="registro" id="rCod" onsubmit="return registroCs()" >
        <input type="text" class="security"  maxlength="1" id="rCod1" required>
        <input type="text" class="security"  maxlength="1" id="rCod2" required>
        <input type="text" class="security"  maxlength="1" id="rCod3" required>
        <input type="text" class="security"  maxlength="1" id="rCod4" required>
    <div class="infoRegistro">
        <p>Recordalo, lo vas a necesitar siempre que necesites Cargar Saldo</p>
    </div>

    <input class="botonRegistro" type="submit" value="Continuar" id="ContinuarRegistro" >
    </form>
</div>

this is my code js

function registroCs(){
		cs1= document.getElementById("rCod1").value;
		cs2= document.getElementById("rCod2").value;
		cs3= document.getElementById("rCod3").value;
		cs4= document.getElementById("rCod4").value;
		
		if ( cs1.length > 1 || cs2.length > 1 || cs3.length > 1 || cs4.length > 1  ) {
			error= true;
		} else if (cs1 != "" && cs2 != "" && cs3 != "" && cs4 != ""){
			error= false;
		}

		if (error == false) {
			alert("a otro lado");
			document.location.href = "registro2.html";
			return true;
		}

	}

if anyone has an idea why it does not generate the redirection to the next page and can share it would be very helpful

Here is an example. In the action you must place the page that will process your form and the input must have attribute name . Now, when you do the "redirection" in your code you use a static Html address "registro2.html", not a script, so it is not clear how you intend to process the data that the user enters in the form. At the moment I will use the url below in my action.

<form class="registro" id="rCod" action="http://jkorpela.fi/cgi-bin/echo.cgi" 
    onsubmit="return validar()" >
    <input type="text" class="security"  maxlength="1" id="rCod1" name="rCod1" required />
    <input type="text" class="security"  maxlength="1" id="rCod2" name="rCod2" required />
    <input type="text" class="security"  maxlength="1" id="rCod3" name="rCod3" required />
    <input type="text" class="security"  maxlength="1" id="rCod4"  name="rCod4" required />
    <div class="infoRegistro">
        <p>Recordalo, lo vas a necesitar siempre que necesites Cargar Saldo</p>
    </div>

    <input class="botonRegistro" type="submit" value="Continuar" id="ContinuarRegistro" />
</form>

In the Javascript you do the validation. From what I understood from your comments and code, the data is valid as long as something has been written.

function validar() {
    cs1 = document.getElementById("rCod1").value;
    cs2 = document.getElementById("rCod2").value;
    cs3 = document.getElementById("rCod3").value;
    cs4 = document.getElementById("rCod4").value;
    return cs1.trim() != "" && cs2.trim() != "" && cs3.trim() != "" && cs4.trim() != "";
}

Note: Since the form tag does not have method attribute, it is being sent by GET.
