What I want to do is redirect to another page once the user confirms that action.

The code I have so far is the following:

window.onload = function(){
        var pagar = document.getElementById(claspagar); 
        claspagar.onclick = function(){(if confirm (location.href = ("checkout.html"))};
             else("Continua comprando")
             }
        }

I am a newbie and I am learning on my own, I would like to know if it is implemented in the correct way, in the Dreamweaver it marks me a syntax error.

Since you want to get an address to another web page the confirm is poorly implemented, what you want to do could be done like this:

window.onload = function(){
  var r = confirm("Seguir comprando?");
  if (r == true) {
    alert("Confirm aceptado"); //alert para comprobar la opción elegida
    //aqui haces la redirección, podrias usa location.href

    /************REDIRECCION**********/
    //window.location.href = "http://ejemplo.com";
    
  } else {
    alert("Confirm cancelado");
  }
}

We will look at the code line by line to see what is right and what is (or may be) wrong:

window.onload = function(){

This line has no fault with the naked eye.

    var pagar = document.getElementById(claspagar);

This line may contain a failure. claspagar is a variable, if it is not defined, you will receive an error here. If it is defined, then pay will have the element with ID defined in variable claspagar .

The following parts I will separate into different lines to analyze them little by little:

    claspagar.onclick = function(){

This is an error, or it was the previous step. So claspagar is a string with the ID of an element, then it can not be assigned an event onclick , if it is an element it can be assigned a click handler, but then the previous step would fail. What I imagine is that instead of claspage.onclick what you want to do is pagar.onclick .

      (if confirm (location.href = ("checkout.html"))

The syntax of this is incorrect. Checking the if should go in parentheses, in addition, there are three opening parentheses and only two closing parentheses.

};

This closing would correspond to the claspagar.onclick function, which will make the next part incorrect:

         else("Continua comprando")
         }

This code is orphaned. I should go with if , but since it was closed incorrectly, it does not make sense. Also, ("Continue buying") is just a string and does not make sense on its own, I guess you want it to go with a console.log or a alert . The closing key does not correspond to any opening key (one is missing in else ).

This would be the closing of the window.onload function and it's fine.

Solving the errors above, the code would look like this (assuming that claspagar is a variable with the name of the ID, if it is the name itself, you should quote it):

window.onload = function(){
    var pagar = document.getElementById(claspagar); 
    pagar.onclick = function(){
        if (confirm("Estás seguro?")) {
            location.href = "checkout.html";
        } else {
            alert("Continua comprando");
        }
    }
}
