По какой-то причине мой ajax.responseTest, исходящий из моего PHP, не будет правильно оцениваться в условном коде javascript, который у меня ниже. Ajax.responseTest возвращается как «signup_success» (я проверил его с полем предупреждения, и он определенно вернется правильно), но условный код в моем JS-коде не будет правильно оцениваться.
Вот javascript:
else { _("signupbtn").style.display = "none"; status.innerHTML = 'please wait ...'; var ajax = ajaxObj("POST", "signup.php"); ajax.onreadystatechange = function() { if(ajaxReturn(ajax) == true) { if(ajax.responseText != "signup_success"){ status.innerHTML = ajax.responseText; _("signupbtn").style.display = "block"; } else { _("sign").innerHTML = ajax.responseText; window.scrollTo(0,0); _("signupform").innerHTML = "OK "+u+", check your email inbox and junk mail box at <strong>"+e+"</strong> in a moment to complete the sign up process by activating your account. You will not be able to do anything on the site until you successfully activate your account."; } } } ajax.send("u="+u+"&e="+e+"&p="+p1+"&g="+g); } Если я изменил логический оператор в "ajax.responseText! =" Signup_success "" на "==", будет выполняться блок else, поэтому перед условной логикой не будет какой-либо другой проблемы, и я протестировал ее и PHP (ниже ) ОПРЕДЕЛЕННО возвращает «signup_success». Как вы думаете, что может быть в этом утверждении «если»?
Вот PHP для справки:

Как я уже сказал, «signup_success» в конце скрипта PHP определенно срабатывает, но JS выше не будет правильно его оценивать.
Заранее спасибо!
Предполагая, что ссылочный PHP-код размещен правильно, у вас есть ведущий пробел в вашем скрипте:
<?php ^^^^
И выход будет:
signup_success
Попробуйте удалить ненужные пробелы из вашего скрипта или обрезать responseText:
if(ajax.responseText.replace(/^\s+|\s+$/g, "") == "signup_success") ...
