jQuery Ajax HTML替换

Question

My question is simple I receive string and a number but only number show up How I can display both?

     $.ajax({
            type: "POST",
            url: "data.php",
            data: "act="+nr,
            success: function (result) {

                var arr = JSON.parse(result);

                if ($.isArray(arr) == true) {
                    $.each(arr, function (i, n) {
                        $('#s_main #s_info').html("<p>+" + n + "</p>")
                    });

                }

            }
        })
    }); //ends here

---

my php:

$act = $_POST['act'];

$output =array();
$act2 = "TXT!!!";
array_push($output,$act);

echo json_encode($output);

By the way when i use append instead of html the result is correct but it will stack on and not delete the previous data

What you are getting in return is a JSON Object.

if ($.isArray(arr) == true)

This line shouldn't return true becuase an object is not an array. If the JSON.parse() did not work it will return a value that will equate to false. So you can simply test the returned object to see if it was successful.

var jsonObj = JSON.parse(result);

if (jsonObj) {
  $.each(jsonObj, function (index, value) {
    $('#s_main #s_info').html("<p>+" + value + "</p>")
  });
}
