Я пытаюсь представить форму PHP, используя jquery $.ajax(); , Его подача успешно, но когда я пытаюсь предупредить сообщение- alert(SUCCESS); на успех. Это не. Какие-нибудь догадки?
КОД:
$.ajax({ url: 'basic_cms_manager_home_fb_form_submit.php', type: 'POST', data: formData, cache: false, dataType: 'json', success: function(data, textStatus, jqXHR) { if (typeof data.error === 'undefined') { // Success so call function to process the form alert("SUCCESS"); console.log('SUCCESS: ' + data.success); } else { // Handle errors here console.log('ERRORS: ' + data.error); } }, error: function(jqXHR, textStatus, errorThrown) { // Handle errors here console.log('ERRORS: ' + textStatus); }, complete: function() { // STOP LOADING SPINNER } });
ПРИМЕЧАНИЕ. Я уже пробовал: console.log (данные); n других трюков. Мой вопрос в том, почему Alert не работает, когда работает весь скрипт и почему он дает parseerror?
SUCCESS – это не переменная, а строка. Вам нужно поставить кавычки вокруг него, как alert("SUCCESS");
Кроме того, использование методов .success и .error устарело. .done этого используйте .done и .fail или вы можете просто сделать следующее
$.ajax({ url: 'basic_cms_manager_home_fb_form_submit.php', type: 'POST', data: formData, cache: false, dataType: 'json', success: function(data) { alert("SUCCESS"); console.log('SUCCESS: ' + data.success); }, error: function(jqXHR, textStatus, errorThrown) { // Handle errors here console.log('ERRORS: ' + textStatus); }, complete: function() { // STOP LOADING SPINNER } });
Еще одна вещь
Typeof null возвращает объект, поэтому, если data.errors имеет значение NULL, ваша проверка завершится неудачей. Рассмотрите возможность
if (!data.errors) { ... }
если вы хотите сохранить свой код.
data действительны JSON data.error с сервера, возможно, это не так, как вы думаете. Используйте console.log чтобы определить его истинное значение. Кроме того, измените его на нечто более значимое, как data.status => 'success' или 'fail'
Просто. Удалить – dataType: 'json'; & отправить все данные с помощью – formdata.
