我正在尝试为我的物理课程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（以及其他人）之前的分数。我所拥有的是一个名为“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，但似乎它没有向PHP发送数据或它可能是PHP不是写入文本文件。我很确定它不是后者，因为我已经一次又一次检查了我的PHP。
的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();
}
});
});
});
});

答案 0 :(得分：5)
您的data参数看起来很糟糕：
data: {"finalscore: score, name: fullname"},
应该是：
data: { "finalscore": score, "name": fullname },
data必须是一个关键值对。
您的PHP脚本可能也不是非常健壮，如果输入它不期望的应抛出错误。它有点高级但你希望你的脚本表现得那样。验证您的输入并提前崩溃将为您节省大量时间从长远来看:)然后您不必说像“我认为这很好”之类的东西，因为您将知道
答案 1 :(得分：0)
您的数据参数应如下所示
data: {finalscore: score, name: fullname},
