Hi, I’m a little layy with scripts still. I ask for help, if possible.

I got 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);

                    }
                });

            });

Use the window.location.reload().ajax(); for when saving, it clears all fields on the screen, but when an error occurs on the page, it simply clears the fields too, I just want to clear the fields when everything goes right and not when it goes wrong.

If anyone can help me, I’d appreciate it.

What are you calling that $.ajax? You won’t have a <form> or <a> what is being called? What is this ...reload().ajax()?

This Reload(). ajax() is really weird.

I call the ajax every time I click the save button, I don’t have a <form> or <a> to be called, that Reload(). ajax() makes all my form clean, but it cleans up until the error, wanted some way to just clean up if everything’s all right.

It seems to me that after the success, he wants to re-load the page. But then it doesn’t make sense to re-load using Ajax.

I tried to use after the success call Function function limpiar() {
 $("id_cliente").val("");
 $("nome_cliente").val("");
 $("id_vendedor").val("");
 $("nome_vendedor").val("");
 $("Tot_bruto").val("");
 $("Tot_desc_prc").val("");
 } Limpar(), but not clean.

@Alyssonbormann You can give an example of which error can appear that also clears the fields?

Error if the user does not enter a name, or id, even basic validation, that is being treated within my code and not by script

Missed putting # ->> $("#id_cliente").val(""); on each of the selectors.

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 run:

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

Or, if the form is cleared is tied to the validity of the answer:

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

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

Or as pure javascript (comment hint):

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

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

Remember to change #form by the identifier of your form that suits you best.
