How do I pop a simple alert box via AJAX?

Here's my code in the tag:

<script>

function saveQuantity(quantity) 

{

  $.ajax({



  alert(quantity);



  })

}

</script>

and here's my HTML:

<form name=frmQuantity>

 <select name=owned id=owned onChange=saveQuantity(this.value);>

  <option selected=selected value=0>0</option>

  <option value=1>1</option>

  <option value=2>2</option>

  <option value=3>3</option>

  <option value=4>4</option>

  <option value=5>5</option>

  <option value=6>6</option>

  <option value=7>7</option>

  <option value=8>8</option>

  <option value=9+>9+</option>

 </select>

</form>

Why isn't this working? What am I doing wrong?

For what you are writing you don't need ajax, but I guess you want to do an ajax call and on success alert.

If you only want to alert, this will do the trick:

<script>

function saveQuantity(quantity){

alert(quantity);

}

</script>

To do an ajax call and alert on success, do it like this:

<script>

function saveQuantity(quantity) 

{

  $.ajax({

  url:/path/to/executing_script.php,

  type:POST,

  data:{quantity : quantity}

  success:function(data){

  alert(data);

  }



  });

}

</script>

You need to echo the updated quantity on the executing_script.php to show it in your alert
