我是一名将在线进行实验的学生。
参与者访问一个网站（这个版本的更复杂版本：http://auforskning.rf.gd/TEST2.php），它将跟踪a）他们按下哪些按钮，以及b）按下按钮的时间。这是为了跟踪每个参与者在阅读信息上花费的时间。
然而，有一个问题：参与者必须按“提交”＃39;或者＆＃39;下一步＆＃39;为了存储信息。如果他们读取框后面的信息（按预期）并关闭窗口，数据将会丢失。
有没有办法连续存储数据，以便数据只是关闭窗口时不会丢失？

编辑： javascript函数中有很多内容。其中很多是从表单导出和导入值。没有 真的很沮丧，我无法确定我的尝试 以下内容不会破坏您数据的完整性 请考虑雇用某人来纠正这个问题。这可能是一个相对简单的改变和谷歌的'freelance javascript 开发者'会帮你找人。
该代码将单词'submit','submit','submit'提交给名为timefunction的函数。除了暗示这段代码是潜意识消息传递的一种形式，使你的使用更加从属（/笑话），看起来该函数在别处定义。这意味着我们无法分辨它究竟做了什么。 mlweb.js是一个外部javascript文件，在本页开头链接，这让我相信它是定义该函数的地方（这意味着处理该函数的所有代码都来自那里）。
但是，使用submit方法调用该函数的onclick按钮有明显的链接。 onClick=timefunction('submit','submit','submit')可以根据不需要点击的其他条件进行复制。
例如，如果您希望提交数据，如果有人试图离开页面（如果他们先提交，可能会导致问题。）
粗略代码
window.onbeforeunload = timefunction('submit','submit','submit');
此代码会告诉浏览器在关闭之前将这三个单词发送给此函数。
由于该代码似乎只是发送文本值（可能提示timefunction特别执行某些操作），可能会有一个值可以更改以记录它是一个关闭事件而不是提交。但是我们不知道哪一个没有看到其他代码。如果是我的代码，我会一次更改一个。但是我会不建议你这样做，因为你不知道其余的是什么。
然后你在表单上执行了两个操作，一个是onSubmit="return checkForm(this)"，它似乎是一个表单验证器，以确保所有内容都正确填充。您可以添加此步骤以确保它具有，但现在您将尝试阻止它们关闭窗口，并且错误地告诉他们不提交它。
然后表单实际提交给save.php，我们也看不到。同样，我们可以发送表单详细信息（按原样），就像它已提交一样（没有验证）。我们会通过将document.forms["mlwebform"].submit();与前面的代码相加来实现。
我们可以挤压表单验证，但我不确定返回结果是什么。这有两个选择。
喜欢这样
//no validation!!!
window.onbeforeunload = function() {
timefunction('submit','submit','submit');
document.forms["mlwebform"].submit();
}
//with possible validation
window.onbeforeunload = function() {
if (checkForm(document.forms["mlwebform"])) { //if the validator returns true, continue
timefunction('submit','submit','submit');
document.forms["mlwebform"].submit();
} else { //if the validator does anything else, say so
MsgBox("Apologies, something went wrong");
}
}
此COULD可以使用，具体取决于其他文件中的功能。我会先尝试第二个，因为验证会很棒。否则使用第一个作为后退。
我会在loadMatrices();之后和</script>之前添加此内容。
<强>结论
看mlweb.js会有所帮助
我们可以尝试伪造提交会做同样的响应（这可能会导致错误，我们不知道如何处理）
如果你是勇敢的，并且通过在这个阶段通过实验倾倒错误和未经验证的数据来弄乱你的数据没有/很少的后果，那么测试上面的2个代码示例。
如果此阶段数据的完整性很重要，或者这是一个实时/生产网站，那就不要了！让某人正确评估代码
