ajax call function is not defined error

Question

I'm using jquery's ajax function and am getting error:

'getQty is not defined'

Where is my mistake?

jQuery:

function getQty()
{
  var dataString = "itemId=" +$(".itemId").val();
  $.ajax({
    type: "GET",
    url: "getQty.php",
    data: dataString,
    success:function(data)
    {
      $(".qty").val(data);
    }
  });
}

HTML:

 <a href="screen.php?itemId={$itemArray[sec].itemId}" class="btn itemId" name="itemId" onClick="getorder();">{$itemArray[sec].itemNm}</a>

Answer 1

最佳做法是

$('#myLink').click(function(){  getQty(); return false; });

Answer 2

You're calling the wrong function in the HTML:

onClick="getorder();"

should be:

onClick="getQty();"
