无法使用jQuery Ajax POST方法发布到PHP

Question

I am trying to send data to a PHP file using jQuery Ajax POST method but the PHP file doesn't seem to get the data from Ajax.

if (y == 5) {
  window.location = "../flashcard/indexFlashcard.php";
  $.post("indexSatzeargenzung.php", data:{p: punkt});
}

This is the way I'm trying to post the data and the PHP code that normally should get the data is:

$punkt = $_POST["p"]; echo $punkt;

It displays this notice:

Notice: Undefined index: p in xxx\\xxx\\indexSatzeargenzung.php on line 2

I'm really stuck here.

Answer 1

Use the jQuery Library. jQuery post() Method

Answer 2

$.post( "indexSatzeargenzung.php", {p: punkt})
    .done(function( data ) {
        window.location = "../flashcard/indexFlashcard.php";
    });

Answer 3

You can use .ajax instead of .post method:

if (y == 5) {
    $.ajax({
        type: "POST",
        url:"indexSatzeargenzung.php", 
        data: "p=" + punkt,
        complete: function() {
            window.location = "../flashcard/indexFlashcard.php";
        }
    });
}
