Question

我使用了以下Javascript。如果时间结束，则必须通过提交表单将其重定向到下一页“ result.php”。但是很遗憾，显示的页面为空。在我的表格下面，该表格必须发送到下一页“ result.php”。我想知道如何发送此表单并重定向到下一页。如何使用此Javascript发送表单以使我的页面正常工作？

var hoursleft = 3;
var minutesleft = 0;
var secondsleft = 0;

var end1;
var progressBar = document.getElementById('progressBar');
if (localStorage.getItem("end1")) {
  end1 = new Date(localStorage.getItem("end1"));
} else {
  end1 = new Date();
  end1.setMinutes(end1.getMinutes() + minutesleft);
  end1.setSeconds(end1.getSeconds() + secondsleft);
  end1.setHours(end1.getHours() + hoursleft);
}
progressBar.max = end1 - new Date();

var counter = function() {
  var now = new Date();
  var diff = end1 - now;
  diff = new Date(diff);
  var sec = parseInt((diff / 1000) % 60)
  var mins = parseInt((diff / (1000 * 60)) % 60)
  var hours = parseInt((diff / (1000 * 60 * 60)) % 24);
  if (hours < 10) {
    hours = "0" + hours;
  }
  if (mins < 10) {
    mins = "0" + mins;
  }
  if (sec < 10) {
    sec = "0" + sec;
  }
  if (now >= end1) {
    clearTimeout(interval);
    localStorage.setItem("end", null);
    localStorage.removeItem("end1");
    localStorage.clear();

    if (confirm("TIME UP!"))
      window.location.href = "result.php";
    //alert("Time finished!");

  } else {
    progressBar.value = progressBar.max - (end1 - now);
    localStorage.setItem("end1", end1);
    document.getElementById('hours').innerHTML = "<b>" + hours + "</b>&nbsp;&nbsp;&nbsp;" + ":";
    document.getElementById('mins').innerHTML = "<b>" + mins + "</b>&nbsp;&nbsp;&nbsp;" + ":";
    document.getElementById('sec').innerHTML = "<b>" + sec + "</b>";
  }
}
var interval = setInterval(counter, 1000);
