Get jQuery Error if PHP Breaks
- by Norbert
I have a PHP script that breaks if a variable is not populated and it isn't added to the database, but jQuery handles this as a success and I get this error:
TypeError: Result of expression 'data' [null] is not an object.
Here's the jQuery script:
$.ajax({
type: "POST",
url: "/clase/do-add",
data: $("#adauga").serialize(),
dataType: "json",
error: function (xhr, textStatus, errorThrown) {
alert('Try again.');
},
success: function(data) {
var dlHTML = '<dl id="' + data.id + '"> [too long] </dl>';
$('form#adauga').after(dlHTML);
$('#main dl:first').hide().fadeIn();
adaugaClasaSubmit.removeAttr('disabled');
adaugaClasa.removeAttr('readonly');
adaugaClasa.val("").focus();
}
});
