Hello, I'm a bit lay with scripts yet. I ask for help, if at all possible.

I have the following script :

 $.ajax({
                    type: "POST",
                    url: "/PreVenda/GuardarPreVenda",
                    dataType: 'json',
                    data: JSON.stringify(json),
                    async: false,//this makes the ajax-call blocking
                    contentType: 'application/json;charset=UTF-8',

                    success: function (response) {
                        alert(response);
                        window.location.reload().ajax();
                        valid = response.valid;
                    },
                    error: function (error) {
                        alert(error);

                    }
                });

            });

I use window.location.reload().ajax(); to save when it clears all the fields on the screen, but when an error occurs on the page, it simply clears the fields too, I just want it to clear the fields, when everything is ok and not when give errors.

If someone can help me, thank you.

You are using window.location.reload() just to clear the form fields and this is not absolutely recommended.

Let's say your form is <form id="form"> , then make a selector on the form identifier and execute:

success: function (response) {
    $("#form")[0].reset();
    valid = response.valid;
}

Or, if the form is cleaned, it is linked to the validity of the response:

success: function (response) {
    valid = response.valid;

    if (valid){
        $("#form")[0].reset();
   };
}

Or as pure javascript (suggestion in comment):

success: function (response) {
    valid = response.valid;

    if (valid){
        document.getElementById("form").reset();
   };
}

Remember to swap #form for the identifier of your form that best suits you.
