JQuery function not found

Question

following code:

// also tried function getDeletedDates()
var getDeletedDates = function()
{
 var s = new Array();
 $(".deleted").each(function(i, e) {
 s.push($(e).attr("data-day"));
 });
};
 $(function()
 {
 $("#delete_send").click(function() {
 alert("drin");
 $.ajax({
 url: "delete.php",
 type: "POST",
 data: ({deleteDates : getDeletedDates()}),
 dataType: "json",
 success: function(msg){
 alert(msg);
 },
 beforeSend: function(){
 alert("Lösche folgende Urlaubstage: "+ getDeletedDates().join(", "));
 },
 error: function(x, s, e) {
 alert("Fehler: " + s);
 }
 }
 );
 });
 });

But i come into beforeSend() he always says "getDeletedDates() undefined" Why is this, i declared the function in global scope?

thanks in advance.

Answer 1

Your function doesn't return anything, so the result will be undefined. Change the method to return the array.

UPDATE:

When you do getDeletedDates() it is evaluated to undefined, because of the lack of return result. This is why getDeletedDates() is undefined is the error message.

• Weidling C: ohh thank you this helped, but I'm confused why it says "getDeletedDates() is undefined" but thank you very much!

Answer 2

You are calling your function, but the function is defined as a variable/pointer and doesn't return anything. The following modification should work (not tested):

function getDeletedDates()
{
 var s = new Array();
 $(".deleted").each(function(i, e) {
 s.push($(e).attr("data-day"));
 });
 return s;
};
