I have a problem with AJAX, I have a field in HTML:

<input type="hidden" id="numreporte" name="numeroreporte" value="30" >

And I have the following function:

function valnumreport(){

 $.ajax({
        type: 'POST',
        url: 'ruta.php',
        data:'numeroreporte='+ document.getElementById('numreporte').value,
        success:function(response){

   alert (numeroreporte);


  }
  });
}

And I call the function with a onchange :

onchange ='valnumreport()'

What I want is to send the value of hidden to another page with an event onchange but it does not send it, I'm just working with AJAX so I do not have much knowledge.

Well to be able to answer you I will assume the following:

That you have a selector with n options to deploy.

That you have a hidden input field from which you expect to take the value to send to your page 'ruta.php' once you change the selection of the select

The attached link simulates the sending of the hidden field value to an external server, as a response from this external server you receive the same value that you sent, that is, the .value of the hidden field.

Example of sending hidden value to external server

I think this solves part of your question; If not, let me know.

<input type='text' class='form-control' id='numreporte' name="numeroreporte"  maxlength='300'   required='required' autofocus>


function valnumreport(){

$.ajax({
    type: 'POST',
    url: 'ruta.php',
    data{
    'numeroreporte': $('#numreporte').val(),
    }
   success:function(response){
   alert (numeroreporte);
  }
  });
}
