Get Attachments using SPServices in SharePoint 2013

$().SPServices({

operation: "GetListItems",
async: false,
listName: "listname",
completefunc: function (xData, Status) {
$(xData.responseXML).SPFilterNode("z:row").each(function() {
$().SPServices({
operation:'GetAttachmentCollection',
listName: "listname",
ID: $(this).attr("ows_ID"),
completefunc: function (xData, Status) {
$(xData.responseXML).find("Attachments").each(function() {
alert($(this).text());
});
}

});
});
}
});


But theres a much more better way to do it,Thanks to Marc:
    var p = $().SPServices({
    operation: "GetListItems",
    listName: "listname",
    CAMLQueryOptions: "<QueryOptions>" +
            "<IncludeAttachmentUrls>TRUE</IncludeAttachmentUrls>" +
        "</QueryOptions>"
});
 
p.done(function() {
 
    $(p.responseXML).).SPFilterNode("z:row").each(function() {
     
        var attachments = [];
 
        var att = $(this).attr("ows_Attachments");
        if(att !== "0") {
            attachments = att.split(";#"); // Now you'll have an array of attachment URLs
        } else {
            // att will be "0", indicating that there are no attachments
        }
     
    });
 
});
