如何从jquery PHP返回json对象

Question

I want to return a JSON object from jQuery but i get the following error:

VM93:1 Uncaught SyntaxError: Unexpected token o in JSON at position 1.

The following is my code:

<?php
  $soapclient = new SoapClient();
  $params = array("id" => "31");
  $response = $soapclient->GetMovieById($params);
  echo json_encode($response);
?>

<script>
$(document).ready(function(){
    $("#mylittleweewee").click(function(){
        $.ajax({
            url: "soap.php",
            type: "POST",
            dataType: "json",

            success: function(response){
                console.log(response);
                var json = JSON.parse(response);
                console.log(json);
            }
        });
    });
})
</script>

As you are specifying dataType: "json", jQuery already performs the JSON decoding for you, so your response is already an object. You should remove this line:

var json = JSON.parse(response);

... and work with response as an object.
