I have the following script on ajax:

  $("#contato").on("submit", function () {
    if($('#descricao').val() == "")   {     //verifica apena o texto
        alert("Descrição não está preenchida!");
        $('#descricao').siblings().each(function(){
          if ($(this).children('iframe').length){
             var iframe=$(this).children('iframe')[0];
             iframe.contentWindow.focus();
          }
       });
       return false;
    } 

    $.ajax({
     url: "_required/email.php",
     type: "POST",
     data: $("#contato").serialize(),
     success: function(retorno){

        if (retorno.trim() == "OK") {
          resposta = "E-mail enviado com sucesso!";
        } else {
          resposta = "Erro no envio do E-mail";
        }
       $(".resposta").css("display", "block");
       $(".resposta").html(resposta);             
     }
    });

    return false;

  });

return in Success:, brings back a query to a script php that returns two values, either OK or ERROR.

In that part

   $(".resposta").html(resposta);

If I change to

   $(".resposta").html(retorno);

Call me back 

OK

But keeping 

   $(".resposta").html(resposta);

Prints

"Erro no envio do E-mail";

Where am I going wrong?

    What gives console.log(retorno.length);?

  • it is, 6; but php only returns 2 which is OK. There is something else coming. Please have a look: http://www.hotplateprensas.com.br/contact.php. can add any email to this page

  • Forehead if (retorno.trim() == "OK"){... works?

  • 1

    It worked. Where are these hidden characters coming from? Is it from a file with GOOD signature?

I took a look at your website and the return of AJAX.

I saw this:

At first it seems correct, the OK is there... but the problem is that it has blank space and line break before of OK, making it a string with more characters than only OK.

Looking at a breakpoint in Javascript confirms:

You have to fix that in PHP. And that code is not in the question. Somewhere you’re doing echo empty or with whitespace.

To "hide" the problem in Javascript you can do 

success: function(retorno){    
    if (retorno.trim() == "OK") {

or

success: function(retorno){    
    retorno = retorno.split(/\W/).join('');
    if (retorno == "OK") {

    I’ll take it easy, thanks!

  • Please, I’ve added to the question all the files involved. I couldn’t find where these spaces are being generated and none of these files have BOM signature. And I also put all the Java Script

  • @Carlosrocha tests to remove the error tools that are at the beginning of the file, ini_set etc....

  • 1

    Look, it worked. But you can’t understand why these directives are inserting these characters!

In ajax there are some functions, one of them Success and the other error.

  $.ajax({
                url: url
                success: function (parametro) { ... }, 
error: function(){....}

use the error of the function that will help your life.
