Ajax does not recognize the echo of PHP [closed]

Navigation
1

I have a simple ajax: 

$.ajax({
    url:"php/exemplo.php",
    type:"POST", 
    data:new FormData(this),
    contentType:false,
    cache:false,
    processData:false,
    success: function(resposta){
      if(resposta == '<nome>'){
        alert('deu certo');
      }
}});

In PHP I give echo "<nome>"; and this <nome> arrives in ajax right (I checked with an alert) ... but if it does not understand that it is <nome> , it does not fall into if ...

What could be the error?

The error was what they were talking about, some empty PHP space was coming. I was able to adjust using Jquery trim: jQuery.trim ()

Looking like this: 

if($.trim(resposta) == '<nome>'){

Probably the Ajax return is coming with some space or line break along with <nome> , so if understands that answer is not exactly <nome> .

One way to work around this is by changing the comparison way with indexOf : 

if(resposta.indexOf('<nome>') != -1){
  alert('deu certo');
}

You can use the native .trim() of JavaScript and make if(resposta.trim() == '<nome>'){ .

So clean up blanks and line breaks before the comparison.

Make sure that the <nome> obtained in AJAX does not have any more space before or after s and you are using UTF-8 without BOM.
