我使用了 Java Scipt 毫秒计时器，我想在用户提交窗口时将计时器值传递给 php。谁能帮忙解决如何将 JS 计时器值发送到 PHP 的问题？
我的 JS 定时器代码如下:-
当用户提交表单时，我需要将 Seconds.Millisecond 值传递给 PHP。

最佳答案
我已经为您构建了一个具有最佳性能和最简单处理的 JS fiddle:
将一个隐藏的输入放入表单中，设置一个间隔函数来更新输入并在提交时停止计时器。该值包括微秒，但我会留给您找到一种方法来消除它；-)
var startTime;
var endTime;
var timer;
$(document).ready(function() {
startTime = performance.now();
timer = window.setInterval(function() {
endTime = performance.now();
$('#timer').text(endTime - startTime);
});
});
$('#myForm').on('submit', function() {
window.clearInterval(timer);
$('#millisecondValueInForm').val(endTime - startTime);
return false; //remove this later in real script because it prevents form from submitting
});
