I need help to write a if statement using jquery. So if results.d.ProductName is empty do not show `$(prdHtml).html(html);
$.ajax({
type: "POST",
url: "Services.asmx/GetProduct",
data: '{ "fieldName": "' + id + '"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(results) {
var html = '<h3>' + results.d.ProductName + '<h3>'
+ '<a href=""' + results.d.Url + '</a>';
$(prdHtml).html(html);
