我正在尝试为我的物理课制作期末考试复习指南，但我希望能够在文本文件日志中查看我（和其他人）以前的分数。我拥有的是一个名为“scorelog.txt”的预制文本文件，我的javascript文件名为“phpjs.js”，HTML文件名为“physics-with-php.hmtl”，我的PHP文件名为“submitlog.php ”。我的问题是：当我最后一次按下我的 html 中的“下一步”按钮时，它会给出警告框，但它似乎没有将数据发送到 PHP或可能是 PHP 没有写入文本文件。我很确定不是后者，因为我已经一次又一次地检查了我的 PHP。
Javascript
$(window).load(function() {
$(document).ready(function() {
var totalQuestions = $('.questions').size();
var currentQuestion = 0;
$questions = $('.questions');
$submitBtn = $('.subBtn');
$questions.hide();
$submitBtn.hide();
$($questions.get(currentQuestion)).fadeIn();
$('#next').click(function() {
$($questions.get(currentQuestion)).fadeOut(function() {
currentQuestion = currentQuestion + 1;
if (currentQuestion == totalQuestions) {
var score = 0;
score = parseInt($("input:radio[name='1']:checked").val()) + parseInt($("input:radio[name='2']:checked").val()) + parseInt($("input:radio[name='3']:checked").val()) + parseInt($("input:radio[name='4']:checked").val()) + parseInt($("input:radio[name='5']:checked").val());
alert("Your score: " + score + " / 5");
var fullname = $('$.FullName').val();
$.ajax({
type: "POST",
url: "submitlog.php",
data: {"finalscore: score, name: fullname"},
success: function(data) {
alert("Your score of " + data + " has been logged");
}
});
} else {
$($questions.get(currentQuestion)).fadeIn();
}
});
});
});
});
