Performs the operation but displays error at the end

Question

I’ve got the code below that’s really pissing me off.

It’s not possible people!

// JavaScript Document// JavaScript Document
$(document).ready(function(e) {

  $("a.excluiFalecimento").click(function() {

      if (confirm('Deseja Excluir esta Nota?') ) {

           $.post ("../_requeridos/excluiFalecimento.php", {

               idFalecimento   : $(this).attr('falecimentoid')

           }, function(retorno){
               alert(retorno)
               if (retorno == "OK") {

                    alert('Excluido com sucesso');
                    location.reload();

                } else {

                    alert("Erro na exclusão");

                }

             }
        );

        return false;

      }

  })


});

I have 4 files exactly the same except for the variable names only.

I got a alert who is printing OK

               alert(retorno)
               if (retorno == "OK") {

But it doesn’t enter the correct block.

And it obviously doesn’t do the Reload.

Where am I going wrong?

Detail, deletion is being done normally.

Answer 1

The return of Ajax comes with white spaces on the edges and not just the pure string.

To solve this, clear the return with the method .trim(), so it is assured to return only the string OK and the if will validate:

if (retorno.trim() == "OK") {
   ...
}

Or (less recommended) you can check if the return has the string OK:

if(~retorno.indexOf("OK")){
   ...
}
